Memorandum submitted by the Department of Energy and Climate Change (UKOG 16)

 

1.         The Department welcomes this opportunity to provide evidence to the Committee’s initial inquiry, into UK offshore oil and gas.   

 

2.         The UK’s endowment of oil and gas resources is a major asset to the country.   The Government’s overall objective for the management of these resources is to maximise their economic recovery over time, and to maximise the consequent benefits to the UK economy and to UK employment.    The underlying geology and the evolution of future oil and gas prices, together with the development of the necessary technology, will be  the dominant drivers of investment and, hence, ultimate recovery levels.    However, Government does have a crucial role to play in ensuring that the regulatory and fiscal regimes help deliver the best possible future for the UK Continental Shelf (UKCS).

 

3.         This memorandum first offers some background information on the broad ambit of the Committee’s inquiry – the extent of the UK's oil and gas reserves and the contribution these can make to the UK's future energy needs – and then some comments on the seven questions specifically identified in the Committee’s call for evidence.

 

 

The extent of the UK's oil and gas reserves and the contribution these can make to the UK's future energy needs

 

4.         The Department publishes estimates of the UK’s oil and gas reserves each year[1].   They are compiled from the oil and gas companies’ estimates of their individual fields’ reserves.    In accordance with standard industry and geological practice, the discovered volumes of oil and gas remaining to be produced are categorised into “proven”, “probable” and “possible” reserves depending on the likelihood of the oil and gas being technically and commercially producible.  “Proven” corresponds to at least 90% probability of production, “proven plus probable” combined corresponds to a 50% probability of production while “possible” has a 10% probability of being produced in full.    As time passes and technology improves, reserves tend to be reclassified, moving from possible and probable into proven.   Typically “proven plus probable” is taken as the central estimate of reserves.

 

5.         The central estimate of oil reserves remaining at the end of 2007 was 780 million tonnes, and the central estimate of gas reserves remaining at the end of 2007 was 647 billion cubic metres (bcm).   

 

6.         Chart 1 in the Annex to this memorandum shows the pattern of UK oil reserves, and cumulative production, over time; Chart 2 presents the same information for gas reserves.    It is clear that, provided exploration work continues, additions to the reserves base will continue to be made, and will continue to support significant oil and gas production for many years to come.

 

Additional and undiscovered resources

7.         The Department also publishes estimates of “Potential Additional Resources” (discovered volumes not currently considered producible for technical or commercial reasons) and “Undiscovered Resources” (potentially recoverable resources in mapped leads that have not yet been tested by drilling).   Potential Additional Resources (PARS) are also reviewed every year, and where appropriate can also be re-classified as reserves if new technical information becomes available or the economics of production improved.    Estimates of Undiscovered Resources are also updated each year, taking into account any new geological information from exploration and appraisal drilling, seismic survey etc.

Total remaining hydrocarbon potential

9.         An indication of the total remaining recoverable resources on the UKCS can be obtained by adding the central estimates for discovered reserves and PARS to a range representing the possible range for undiscovered resources that might become producible in due course.   Figures for resources not yet discovered are naturally subject to a higher degree of uncertainty than those for discovered resources.   But with the increasing maturity of the UKCS, there is understandable interest in the question of how much further production is likely.   To facilitate more meaningful answers to such questions, the Department’s estimates for undiscovered resources now include two mid-range estimates of undiscovered resources - the lower of 5.2 billion barrels of oil equivalent (boe) corresponding to a reasonable estimate of what might be found based on current knowledge, the higher of 8.7 billion boe corresponding to a reasonable estimate of what might be found with better understanding of the basins or better technology.

 

10.       Taking account of this range of possibilities for undiscovered reserves, our current best estimate of remaining recoverable hydrocarbon resources from the UKCS is of a figure of around 20 billion boe.   But it is of course entirely possible that the development of better understanding and technological change will in the event enable higher figures to be reached.

 

UKCS Oil and Gas Production Projections

11.       The chart below shows actual and currently projected UKCS oil and gas production, and actual and currently projected UK demand for oil and gas[2].    As shown, the UK is expected to become increasingly reliant on imported oil and gas.    Nevertheless, UKCS oil and gas production can be expected to amount to a large proportion of our oil and gas needs, and overall energy needs, for many years to come.    This prospect is of great significance for UK energy security, and well as for its economic benefits.

 

 

12.       While central projections of oil and gas production are shown in the chart, there is in reality a wide range of possible outcomes because the rate of production is dependent on a number of different factors including the level of investment and the success of further exploration.   Operators continue to find it difficult to predict production accurately as older fields mature and their reliability reduces.   A significant share of future oil and gas production is expected to come from new fields, compounding the difficulty of making accurate forecasts given the risks of project slippage and uncertain start-up profiles.   The central projections are therefore our best estimates rather than a definitive prediction of future production of oil and gas from the North Sea.   There is similar uncertainty surrounding projections of future UK oil and, especially, gas demand.

 

Oil Production and Reserves

13.       After a dramatic build-up following the start of offshore oil production from the North Sea in 1975, and against a background of rapidly falling dollar oil prices, UK oil production peaked in the mid 1980s ahead of the Piper Alpha disaster in 1988 which resulted in a sudden and dramatic decline in production, due partly to the loss of the Piper field itself, and partly to the effects of extensive work programmes to implement new safety measures.   With recovery of production from existing fields and increasing numbers of new fields coming on stream (following a period of significantly higher development expenditure in the early and mid 1990s), oil production reached a second (and higher) peak in 1999.    Until 1997, exploration activity had maintained the level of discovered oil reserves remaining.   The subsequent lower level of exploration activity has not added sufficient to "ultimate recovery" (i.e. the total of cumulative production to date and estimated remaining discovered reserves) to prevent an overall decrease in remaining reserves.   Unless future exploration activity[3] results in a significant increase in ultimate recovery, the level of discovered reserves remaining (currently representing less than a third of ultimate recovery) will set a natural limit on the level of oil production which, over time, can be expected to continue to decline as remaining reserves are depleted.

 

14.       In the absence of significant new fields starting production or major incremental projects in existing fields, UK oil production tends to decline at 10-15% or more per annum.   However, if (large) enough new fields start production (as happened in 2002, with Elgin/Franklin and Shearwater coming into full production), or there are enough significant incremental projects in existing fields, the decline can be arrested or even temporarily reversed.

 

Gas Production and Reserves

15.       Prior to the late 1990s the rate of natural gas production from the North Sea was, effectively, constrained by the level of domestic demand for gas (with gas from most fields being sold under long-term field depletion buyer's nomination contracts), though throughout the 1980s some demand was met by direct imports from the Norwegian Frigg Field.   The "dash for gas" in the 1990s saw a large increase in demand for gas for power generation and, from 1998 with the opening of the Bacton–Zeebrugge Interconnector, significant exports were possible, allowing UK production to increase faster than UK demand.   An increasing proportion was "associated gas" i.e., produced in association with oil (for example from the oil fields in the central and northern North Sea) rather than from the "dry" gas fields in the Southern Basin of the North Sea.   Gas production peaked in 2000 and has been declining sharply since 2003 as new fields starting production have been too few and too small to compensate for the decline in production from existing fields.   As with oil reserves, estimated ultimate recovery of gas increased through to 1997 as additions from exploration more or less kept pace with the increasing rate of production.   Technical and commercial reassessments have, subsequently, reduced ultimate recovery at the proven plus probable plus possible level.   Remaining gas reserves represent less than a third of the total discovered to date.

 

16.       The rate of decline of UK gas production has until recently been less dramatic than the rate of decline of UK oil production.   Compared with oil production, which exhibits some seasonality (as maintenance tends to be scheduled for the summer months), gas production fluctuates much more over the course of the year, reflecting the strong seasonality of gas demand.

 

 

How can the UK’s remaining offshore oil and gas reserves be exploited most effectively?   What barriers are there to exploiting such reserves?   What steps need to be taken to unlock resources west of Shetland?

 

17.       As discussed in the previous section, the UKCS still has substantial oil and gas resources.   At the beginning of 2008 our central expectation was that 12 billion boe of discovered hydrocarbons had yet to be produced, with additions from fields yet to be discovered estimated to be between 5 to 9 billion boe, giving a best estimate of remaining recoverable resources of around 20 billion boe.

 

18.       Over the course of 2008 the UK’s combined oil and gas production was some 1 billion boe (2.6 million barrels per day); this represents around 60% of the UK’s total energy consumption and 80% of its oil and gas demand.   After more than 40 years of continuous activity, production has however peaked and, without continuing capital investment, would naturally decline at around 10-15% per year in line with other mature basins.   Over the past several years, annual capital investment of some £5 billion per in new and existing fields (see Chart 3 in Annex) has reduced this decline to 5-7.5%.

 

19.       To exploit the remaining resources, both discovered and undiscovered, and to continue to slow the decline,  it is essential both to attract substantial further investment - against fierce competition from oil and gas regions throughout the world - and to maintain a population of oil companies, particularly those with operational skills to identify and then exploit the opportunities in the basin.

 

20.       Clearly, geology and the levels of future oil and gas prices will be key determinants of future investment; and little can be done to influence these.   In a mature basin such as the UKCS, other factors can be equally important to attract investment: the costs of activity must be low; regulation and commercial practices must be appropriate and follow the grain of activity; skills of individuals, of the companies that make up the supply chain, and of licensees, must match the opportunities; technology must be developed to reduce the costs and risks of finding and developing new fields and fully exploiting those already in production; and infrastructure, both facilities and pipelines, must be maintained and accessible.   The policies pursued over the past few years have been designed to achieve these objectives.

 

21.       Licensing policy is aimed at providing regular opportunities for the whole spectrum of companies to access acreage suited to their skills.   The Department has been actively seeking and encouraging new licensees, particularly operators, to come into the basin, and have adapted the types of licences available to meet the needs of the industry.   The Promote and Frontier types of licence have been added to the Traditional licence, all with a structure to encourage activity.   (The Promote licence is a short-life, low-cost licence to encourage exploration and prospect promotion activity; the Frontier licence offers larger areas and longer exclusivity to encourage exploration of challenging territory in the Atlantic approaches.)    Similarly the “Fallow” initiative has been introduced to drive new exploration and development activity on older licences in parallel with the “Stewardship” process which puts pressure on the bottom quartile of fields in production to improve performance.   With the support of the whole range of licensees, these approaches have demonstrably increased the opportunities and levels of activity in exploration, appraisal and development in the basin.    

 

22        We are also working with the industry to reduce commercial and administrative inefficiencies and costs.   Through PILOT (an industry, Government, trade union forum which is chaired by the Secretary of State) industry has produced Codes of Practice for commercial activity between licensees and within the supply chain.   DECC has recently agreed to play a more active role in helping to monitor and enforce these Codes.   To reduce the costs to industry of our administration of the licensing regime we have e-enabled much of the transactional process and have further improvements underway.   We have also worked with industry to enable them to reduce the burden of their necessary obligations to hold geological data.

 

23.       The maturity of the UKCS means that the majority of new finds and developments will be small, and unlikely to be able to support the cost of substantial, dedicated, production and export infrastructure.   It follows that access to existing infrastructure (both pipelines and facilities) on fair and reasonable commercial terms is critical to the full exploitation of the basin.   Through PILOT, industry has developed an Infrastructure Code of Practice aimed at ensuring transparent and timely negotiations for that access.   The Department has agreed to assist in the enforcement of that Code, in particular to help provide an expected timeline for negotiation.   Beyond that function however, the Secretary of State has powers on application to set tariffs and terms for access to infrastructure, and has published Guidance on disputes over third party access, to aid industry in understanding our approach to resolving such disputes.    The nature of access to infrastructure is changing as the basin matures, and the Department, in discussion with industry, is currently revising the Guidance to accommodate these changes. 

 

24.       We see technology development as primarily a task for industry but, where it is appropriate and there is a particular need, we support individual technology development or more fundamental research, particularly where this will encourage the pooling of industry resources.   Projects in the oil and gas field have been supported by the Technology Strategy Board, and DECC has contributed to development and university research projects supported by the industry’s club financing (the Industry Technology Facilitator).   The Department also funds geological and geophysical analysis of parts of the UKCS with the aim of attracting bids for specific areas in licensing rounds. 

 

 

West of Shetland

25.       The area to the west of the Shetland Islands and the Hebrides is the largest remaining area of significant prospectivity on the UKCS, holding some 10 to 20% of UK’s remaining oil and gas.   The area represents a potential 3 - 4 billion barrels of oil equivalent - around 17% of the UK's remaining oil and gas reserves and includes some 10 to 15% of remaining UK gas reserves.   It is remote, being nearly 400 km from the nearest gas terminal, and most of the gas discoveries are too small to support the necessary gas infrastructure on their own  The existing gas pipelines (WOSPS, EOP and FLAGS) do not have capacity in the short and medium term to support major development

 

26.       Exploration and development has been hindered by the lack of gas transportation capacity and no one company or single field has been sufficient to drive the building of this infrastructure.  As a result of the Energy Review in 2006, a Government/industry Taskforce was established to get the right infrastructure in place to the west of Shetland so that, with minimal impact on the environment, development and exploration in the area could be speeded up.    The Taskforce includes representatives from leading oil and gas companies with gas projects that have the potential to start within 5 years:

 

Total                              - operator of the Laggan and Tormore fields

Chevron                         - operator of Rosebank and Lochnagar

BP                                  - operator of the Clair field

ExxonMobil                   - operator of Tobermory

DONG Energy              - participant in Laggan, Rosebank and Tobermory.

 

27.       The Taskforce started work in November 2006, to examine the potential for a multi-field development with gas export to the mainland Scotland.   A range of alternative options including power generation and the production of Liquified or Compressed Natural Gas close to the point of production, were also considered and rejected on at an early stage on cost grounds.   The Taskforce identified four types of gas gathering hub, three of which were located offshore with a direct pipeline connection to St Fergus and the fourth, onshore at the existing Sullom Voe terminal in the Shetland Islands.   All were assessed to be technically feasible.

 

28.       In September 2007a well was drilled by Total into the Tormore prospect close to the Laggan field which identified additional gas.   At the same time Chevron commenced an extended appraisal programme of their Rosebank/Lochnagar discovery in the growing confidence that they had a viable development further to the west.

 

29.       These developments offered better prospects for development, and the Laggan/Tormore and Rosebank/Lochnagar partners co-sponsored an independently managed  process in the autumn of 2008 to test the appetite for third party investment in a basic engineering study and ultimately, in the collective project.   This revealed a potential requirement for about 18 million cu. m/year of gas transportation capacity (equivalent to about 5% of UK annual demand), involving 10 licensees in 3 separate licence groups.

 

30.       Total have now commissioned the basic engineering study for Laggan/Tormore and the work is proceeding primarily on the basis of an onshore gas gathering hub located at the existing Sullom Voe Terminal in the Shetland Islands.

 

31.       For the gas export pipeline, there are two options (see Chart 4):

In either case, the pipeline is expected to have capacity for the 18 million cm/d of gas identified in the third party investment process.   We understand that the partners consider that there is a commercially viable development option for Laggan/Tormore, with development sanction in September 2009 and first production in late 2013.   The parties interested in developments west of Shetland are now moving towards a decision on development later this year which will be followed by a submission of a development plan to the Department for consideration.   The Department considers that this collaborative process has a real prospect of providing infrastructure to deliver gas to the market in 2013/14.    It will be a collective solution that reflects the requirements of players in the West of Shetland area prepared to commit to development. 

 

 

What can be done to minimise the environmental impact of exploiting oil and gas reserves?  How should this be encouraged or financed?

 

32.       A comprehensive framework of environmental protection measures has been developed to minimise the impact of oil and gas activities.   This is embodied in the relevant legislation, consistent with and in large part derived from the legislative framework of the European Community (EC).   In addition, the UK is a signatory to the Oslo and Paris Convention for the Protection of the Marine Environment of the North East Atlantic (the OSPAR Convention).   It is Government policy to implement and apply all of the OSPAR Commission’s decisions and recommendations.

 

33.       This robust offshore environmental protection regime, which covers oil and gas development throughout its life cycle, from the initial licence application to the final decommissioning of facilities, as detailed in the remainder of this submission.  All activities that could potentially impact on the environment are subject to rigorous assessment, and significant activities are controlled through the issue of permits, consents or authorisations.  There is also an inspection and enforcement regime in place to confirm compliance with the conditions included in the environmental approvals.

 

34.       The robust regime is reflected by the industry’s performance, and the UK has a good environmental record with no significant impact on the marine environment resulting from offshore oil and gas activity. 

 

Environmental aspects of  licensing

35.       To meet the requirements of EC Directive 2001/42, transposed into UK legislation by the Environmental Assessment of Plans and Programmes Regulations 2004, a Strategic Environmental Assessment (SEA) is carried out before oil and gas licensing is undertaken.  The SEA is subject to public consultation and evaluates both the individual and cumulative impacts of offshore oil and gas activity at a strategic level.  Licence areas can be withheld if mitigation of potentially adverse effects is not considered to be feasible, or if there is insufficient information available to determine the potential impact of the licensing activity.  For example, the 2008/9 Offshore Energy SEA recommends that an area to the west of the Hebrides and the deepest parts of the southwest approaches should continue to be withheld from oil and gas licensing due to significant gaps in our knowledge of these areas.

 

36.       Following the completion of a SEA, operators are invited to apply for licences in selected areas, usually as part of a licence round.  The licence application process includes an Environmental Competency Assessment.  Applicants must have, or commit to develop, an Environmental Management System (EMS) that satisfies the requirements of OSPAR Recommendation 2003/5; must have adequate oil spill liability provision; and must prepare a high-level Environmental Impact Assessment (EIA) to identify the environmental sensitivities in the area that is the subject of the application.

 

37.       An EMS is designed to achieve the prevention and elimination of pollution from offshore sources; the protection and conservation of the maritime area against other adverse effects of offshore activities; and continual improvement in environmental performance.  All of the 81 licensed operators on the UKCS have an independently verified EMS.

 

Project specific regulation  

38.       The granting of a licence does not automatically confer any rights or permissions for activities within the licensed area, and all proposed projects are subject to an environmental assessment.

 

39.       The Offshore Petroleum Production and Pipelines (Assessment of Environmental Effects) Regulations 1999 implement the EC EIA Directive, and require the operator to undertake an environmental assessment for a wide range of projects.  For all new developments, significant increases in production and large pipelines, the assessment must take the form of an Environmental Statement that is subject to Public Notice.

 

40.       The Offshore Petroleum Activities (Conservation of Habitats) Regulations 2001 implement the EC Habitats and Wild Birds Directives, and apply to all projects and activities.  Where a project or activity could affect the integrity of a protected habitat or species, an Appropriate Assessment (AA) is required to demonstrate that any effect would be insignificant.

 

Activity Specific Legislation

41.       In addition to the project level legislation being applied to activities such as the drilling and testing of wells, all minor pipelines and pipeline works and minor production increases; all activities that could adversely affect the environment are strictly regulated (further information can be found at Annex 2).   Assessments are required for:

·        seismic and other survey activity

·        the use and discharge of chemicals

·        the discharge of oil

·        atmospheric emissions

·        oil spill response

 

42.       Most of these activities are controlled by the issue of activity specific permits, consents or authorisations containing legally binding terms and conditions.  In addition, every offshore installation must be the subject of an approved Oil Pollution Emergency Plan.  The offshore sector is also included in the EU Emissions Trading Scheme.  

 

43.       Whilst the majority of the project and activity level legislation referred to above has been developed specifically to control offshore oil and gas operations, the industry is also subject to non-sectoral environmental legislation that is applied to all marine activities.  For example, all deposits in the sea that are not covered by oil and gas industry legislation will be controlled under the Food and Environment Protection Act (FEPA) 1985, Part II Deposits in the Sea.  The industry is also subject to regulations relating to merchant shipping.  The environmental controls are therefore similar to those imposed on other marine activities and to those imposed on terrestrial activities.

 

44.       In addition, DECC continues to work closely with industry to improve environmental performance, by encouraging initiatives such as the increased use of reinjection for produced water (a by-product of the production process that is contaminated with reservoir hydrocarbons); the preferential use of chemicals with little or no environmental impact; and energy audits to determine the most efficient way to meet power requirements and reduce atmospheric emissions.

 

Environmental aspects of decommissioning

45.       The EIA for a proposed development will include consideration of the long-term impacts, including those arising from decommissioning.  However, there is usually a lengthy period between project sanction and decommissioning, and UK Government policy could change during that period.  There is therefore an additional requirement for a detailed assessment at the time of decommissioning, which is submitted as part of the decommissioning programme.  

 

Enforcement

46.       DECC actively ensures that industry is complying with the conditions included in environmental approvals, following a four step process of audit and review, inspection, investigation and enforcement.    A risk-based inspection strategy is used to prioritise the installations that will be inspected.  Inspections provide evidence and assurance that operators have been, or are complying with the requirements, restrictions or prohibitions imposed upon them by the relevant statutory provisions and that pollution prevention procedures are being implemented. 

 

47.       Offshore environmental incidents involving oil and chemical spills to sea and notifications of non-compliance with permitted activities are reported to DECC.  All reported environmental incidents are reviewed and where applicable action is taken to ensure that response procedures are implemented to minimise the potential impact of any pollution.   Where any spill results in, or there is a threat of, significant pollution, the Secretary of State’s Representative (SoSRep) has the power to take control of the situation.   Although the SoSRep has never been required to take significant action in relation to offshore oil and gas activities, there is close liaison between DECC, the SoSRep, and the industry.   Legislation requires operators to carry out Oil Spill Response exercises to test and further strengthen pollution response. 

 

48.       DECC also collaborates with the Maritime and Coastguard Agency (MCA) to ensure that an effective pollution identification aerial surveillance capability is maintained for UK offshore oil and gas activities within the UK Pollution Control Zone.  At the international level the UK supports the activities of the Bonn Agreement (Maritime Pollution and Prevention).

 

49.       Where oil and chemical spills to sea occur, or breaches of regulatory requirements are identified, the circumstances will be investigated.  If it is considered necessary, enforcement action may be taken to ensure that: preventative or remedial measures are taken to prevent pollution, measures are put in place to achieve regulatory compliance and operators are held to account when failures to comply occur.   DECC has the power to revoke permits, enforce actions, prohibit activities and to prosecute offenders.   There have been 11 reports to the Procurator Fiscal and 9 prosecutions since 1998.

 

Finance

50.       The vast majority of the costs associated with the environmental regime, including the assessment of applications, the issue of environmental permits, consents and authorisations and the associated enforcement activity is met by the offshore oil and gas industry.  In addition to their project costs, including any waste treatment and disposal expenditure, an application or maintenance fee is levied for most permits.   In order to streamline the handling of the large numbers of permits required and to reduce the administrative costs where possible, there are a number of e-commerce developments underway to simplify application and reporting processes.  

 

Case Study – Moray Firth

51.       In 2006, a licence application was received for an area in the Moray Firth that overlapped with a Special Area of Conservation (SAC) for bottlenose dolphins. A draft Appropriate Assessment (AA) was prepared to inform the licensing decision, which concluded that the licensing could proceed, subject to appropriate mitigation measures being employed for specific activities.

 

52.       The AA was subject to public consultation and several detailed responses were received, a number of which expressed concerns about the interpretation of data that had been included in the draft AA.  Following a meeting with many of the relevant stakeholders in January 2009, DECC proposed a substantial research programme, to be funded by DECC and others, that will seek to provide firm data on the significance of the proposed licence area for bottlenose dolphins (and other marine mammals) during the summer months. 

 

53.       The stakeholders welcomed this proposal and it is hoped that the research programme will commence in May 2009.   No decision will be made on whether to issue a licence for this area until the findings have been collated and fed into the AA process.

 

Consulation

54.       Staff within DECC’s Offshore Environment Unit in Aberdeen have a wide-ranging specialist knowledge of environmental issues.  Nevertheless, the value of consulting with other government departments and bodies who may have an interest in the proposals is recognised, and DECC routinely seeks the views of the Centre for Environment, Fisheries and Aquaculture Science (an agency of Defra), the Fisheries Research Services (an agency of the Scottish Executive Marine Directorate), the Environment Agency, the Scottish Environment Protection Agency, the Joint Nature Conservation Committee,  Natural England, Scottish Natural Heritage, the Countryside Council for Wales and many others.  DECC also has a good relationship with industry, and regularly meets both Oil and Gas UK (the industry representative body) and operators to provide advice and discuss the legislative requirements, in addition to making presentations at workshops, seminars and conferences.    

 

Summary

55.       Whilst the continued development of the UKCS offshore oil and gas sector is considered to be crucial to the security of the UK’s energy supply, the Government is committed to ensuring that the impact of oil and gas activity on the environment continues to be minimised.   Legislation adopted over the last 10 years has resulted in the development of a comprehensive, robust and effective environmental regime, which is consistently applied, understood by industry and fully satisfies the UK’s international obligations.

 

 

How effective is the current fiscal and regulatory regime in which the industry operates?

 

56.       The regulatory regimes as regards licensing, and environmental protection, have been addressed in earlier sections of this memorandum, and decommissioning is discussed later.   This section focuses on the fiscal regime.   

 

57.       The North Sea fiscal regime is one of the main mechanisms for capturing for the nation the economic benefit from the UK's oil and gas resources.   In support of its overall objective of maximising the economic recovery of the UK's oil and gas reserves, the Government aims through the North Sea fiscal regime to encourage investment in and production from the UKCS while ensuring a fair return for the UK taxpayer from the UK's national resources.   The regime has been developed and adjusted over time in response to developments in the industry and the economic climate in which it operates, with the introduction, amendment to and abolition of a number of different fiscal measures.

 

58.       Responsibility for the North Sea fiscal regime is split between HM Treasury (HMT) and HM Revenue & Customs (HMRC).    HMT has overall policy lead and leads on policy formulation while HMRC supports HMT and leads on policy maintenance.    Both work closely with DECC in developing policy and DECC plays a central role in interaction between the fiscal departments and industry stakeholders.    The following comments have been agreed with HMT and HMRC.

 

59.       The fiscal regime which currently applies to oil and gas exploration and extraction from the UK and the UKCS consists of three elements:

         Ring Fence Corporation Tax

With some important modifications (e.g. relating to capital allowances and losses), this is calculated in the same way as the standard corporation tax applicable to all companies, with the addition of a "ring fence" and 100% first year allowances for virtually all capital expenditure.   The ring fence prevents taxable profits from oil and gas extraction in the UK and UKCS being reduced by losses from other activities or by excessive interest payments by treating ring fenced activities as a separate trade.   The current rate for non-ring fence profits is 28% and 30% for ring fence profits.   HMRC has recently simplified the general capital allowances regime but this does not impact on the 100% first year allowance rules within the ring fence.

         Supplementary Charge

This is an additional charge of 20% (10% prior to 1 January 2006) on a company's ring fence profits excluding finance costs.   The supplementary charge was introduced from 17 April 2002.

         Petroleum Revenue Tax (PRT)

This is a special tax on oil and gas production from the UK and UKCS.   It is a field based tax charged on profits arising from individual oil fields.   The current rate of PRT is 50%. PRT was abolished for all fields given development consent on or after on 16 March 1993.   PRT is deductible as an expense against corporation tax and the supplementary charge.

 

The marginal tax rate on new fields is thus 50%, while the marginal tax rate on the older fields paying PRT is 75%.

 

60.       A Ring Fence Expenditure Supplement (RFES) assists companies that do not yet have any taxable income for corporation tax or the supplementary charge against which to set their exploration, appraisal and development costs and capital allowances.   The RFES increases the value of unused expenditure carried forward from one period to the next by a compound 6 per cent a year for a maximum of six years.   It applies to all unrelieved expenditure from 1 January 2006.   This is intended to help support new entrants into the basin.

 

61.       The current North Sea fiscal regime gives Government a system that: incentivises investment; creates a fair return to the UK; is simple to operate; has accelerated payments (compared to other sectors); and sets relief against profits / tax paid.   It gives industry: competitive tax rates; immediate tax relief for almost all revenue and capital expenditure; full tax relief for decommissioning expenditure; and Government effectively sharing in risk and reward.   The regime is kept under review.   Since the start of 2006, the Government has been engaged in discussions with industry about "structural concerns" over aspects of the North Sea fiscal regime.   These discussions were driven by concerns, both within Government and industry, that elements of the existing fiscal regime were having a negative impact on investment decisions – and therefore running contrary to Government's wider objectives.   Following almost two years of discussions, Government published a consultation document in December 2007 setting out a range of proposed reforms to the regime to remove anomalies and change elements that Government felt were potentially restricting investment – most of these were taken forward in Budget 2008.   None of these proposals involved changes to tax rates.

 

62.       A further package of reforms to the North Sea fiscal regime was set out at Pre‑Budget Report 2008 which should help encourage investment in the UKCS.   Building on the changes to the North Sea fiscal regime made at Budget 2008, and productive discussions with industry over the past year - involving BERR/DECC as well as HMT and HMRC - HMT and HMRC published a consultation document on the North Sea fiscal regime alongside Pre‑Budget Report 2008.   Supporting investment[4] set out a further package of reforms which should help encourage investment in the UKCS.   In particular, the consultation document raises the concept of a "value allowance" that could be built into the fiscal regime to help bring forward challenging developments.   A number of other proposed changes which responded positively to representations by industry have been widely welcomed by industry.

 

63.       Discussions with industry over the past year have been wide-ranging and the proposals set out at PBR 2008 covered a disparate array of issues.   In addition to the idea of targeted incentives (where Government wished to discuss the potential of a value allowance), they addressed: the North Sea fiscal regime and chargeable gains taxation; a number of fiscal issues arising from "change of use" from oil and gas production to other energy-related activities such as carbon capture and gas storage; and several other features of the PRT regime, including issues concerning licence expiry and simplification of some features of the PRT regime.

 

64.       A consultation period which ended on 13 February 2009 was intended to give stakeholders the chance to comment on the Government's proposals for changes to the North Sea fiscal regime and to engage further on the question of potential fiscal incentives, in particular to discuss the concept of a value allowance incentive in more detail.   It is intended that, if confirmed in light of the present consultation, the package of changes will be finalised at Budget 2009 and legislated in Finance Bill 2009.   Where possible, draft legislation for the proposed measures has been published on the HMRC website to allow interested stakeholders a chance to comment.

 

 

What effect is the recession and the credit crunch having on the industry?    What is the impact on the financing of exploration and development?

 

65.       The impact of the current economic climate on oil and gas companies is significantly different from that on industry more generally.   The key development of the past twelve months for this sector has been the substantial fall in oil prices.   From a peak of almost $150 a barrel in July 2008, prices have fallen to the region of $40-50 more recently.   Though almost all current developments would have been financed and committed in an oil price environment well below the recent peaks – oil prices varied between $50 and $70 a barrel over 2005 and 2006, for example - the sudden fall in prices and the uncertainty about future prices dominate the business outlook for this sector.   Companies have reacted by substantially curtailing exploration expenditure, and by reviewing and in many cases deferring discretionary investment which is not likely to lead to early production.   

 

66.       The credit crunch, by contrast, has been a less salient concern for many players.    The major oil companies, with substantial revenues from production, have relatively little dependence on external finance.    The largest companies have indicated their intention to maintain capital investment levels at global level (ExxonMobil, Shell, Total, BP), although within that broad intention, it appears that some projects may be deferred while the participants seek lower material and supply costs to improve the project economics.   Some medium-sized companies with significant production are similarly placed.   Other medium sized companies, along with smaller companies, are more dependent on external finance.   Those without production, or facing heavy development expenditure, can face serious financial pressures.   A number of companies have been bought by stronger competitors, and one prominent exploration company has gone into administration.   It is worth note that historically the banks most involved in lending for North Sea developments are RBS and HBOS.   The current difficulties of these banks are a complicating factor in the outlook for UKCS investment.

 

67.       An aspect of the current financial freeze with a particular impact on the oil and gas sector is the unavailability of new equity.   This is of particular concern to smaller exploration companies, since banks have never, even in more favourable times, been willing to finance exploration activity.   If these companies cannot raise equity, they will be unable to secure bank loans or project finance for new developments, even if the developments are in themselves viable and project finance otherwise available.   Since most developments involve a group of participants, the inability of even a junior partner to raise finance may hold up or even stall development.

 

68.       Companies in the supply chain, as opposed to those engaged in exploration and production, are broadly speaking exposed to a similar combination of circumstances to those faced by industry at large – a substantial reduction in demand for their products and services, and a very difficult financing climate.   There are many reports of difficulties in obtaining short-term credit or working capital.    Significant numbers of redundancies have been announced.

 

69.       The combined impact on investment must inescapably be a significant fall.   As noted earlier, the maturity of the UKCS as an oil province implies that production will fall by some 10-15% a year if there is no new investment in production.   The benefit of the sustained investment by the industry over recent years – running at an annual rate of about £5 bn - has appeared in a markedly slower rate of decline of around 5-7% a year.   A recent survey of activity intentions by Oil and Gas UK however estimated that capital expenditure in development and drilling may fall by between £1 bn. and £2 billion in 2009.   Industry’s view of the geological attractiveness of the basin has not changed markedly - the decline in investment is a reflection of a combination of lower oil prices making some investments economically unattractive or higher risk, an expectation that costs will fall in the near term, and a reduction in the availability of funding whether internal, equity or bank borrowing.   The impact will be felt particularly sharply in exploration spending, though development work will also be affected over time.    A falling-off of development investment can be expected to result in a progressive increase in the rate of decline, as existing fields decline more rapidly and new fields are delayed or cancelled.    For employment, the industry has estimated that each £1 billion drop in investment will result in the loss of 20,000 jobs.

 

 

How are the skills needs of the sector being met?   How transferable are these skills?

 

Employment numbers and age profile

70.       The number of people in employed directly within the industry is 350,000 with a further 100,000 employed in export activities by supply chain companies, bring the total to 450,000. Within the 350,000 figure 34,000 are employed directly with oil and gas companies and major contractors, 230,000 in the wider supply chain and the remaining 89,000 are jobs supported by the economic activity of the industry. This is an increase in employment of about 30% since 2004. The number of females employed by the industry has increased gradually over recent years with around 1,800 females travelling offshore, the majority of whom are employed in the catering sector. The age profile of females is younger with average age being 34.1 years.

 

71.       There are distinct clusters of high employment within the industry around the UK, with the Aberdeenshire area accounting for 39% of the total employment. The other regions with sizable employment levels are East of England 5%, North West England 6%, and London and the South East 21%.

 

72.       The supply chain mixture of businesses includes the following:

 

Engineering Construction                                16%

Structural metal products                                10%

Technical consultancy                                     9%

Legal services                                                  5%

Business and professional services                  5%

Public administration                                      4%

Renting of machinery                                      3%

 

73.       The average age for the whole workforce is currently 41 years, which is the expected average age of a workforce in the range 20 to 60 years.

 

Training

74.       The industry has its own skills academy – OPITO, based in Portlethen near Aberdeen.   The academy embodies the concept, which Government supports, of employers taking ownership of the skills and workforce development agenda in their sector.   It is therefore able to respond quickly to the specific needs, or emerging needs within, the sector.    OPITO exceeds DFES guidelines for industry led and funded skills academies.   Their goal is to actively coordinate and consolidate the activities, efforts and resources, needed to address employers’ demand for skilled people.   They also have the objective of addressing STEM (science, technology, engineering and mathematics) subjects within schools, as most jobs in the industry require a strong engineering and technical background.    

 

75.       OPITO is working with colleges and universities in particular through the Technician Training programme, which is an exemplar training provision.   It was launched in 2002 and trains around 100 technicians each year with the course lasting around 3 ½ years and there are currently 390 young people in training.   Each year’s intake is determined through a demand forecasting exercise to ensure employment for all those who finish their training.   This is followed by two years practical training and there is a 96% completion rate after 3 ½ yrs.

 

76.       Salient points on OPITO:

 

77.       There are a high level number of training providers within the industry, delivering OPITO standard training - a link on OPITO’s  website (http://www.opito.com) lists these providers and the variety of training they provide.   

 

78.       Falke Nutec who provides offshore survival training to the industry reports high levels of offshore training with 15,000 trainees going through the offshore survival course in the last year.

 

79.       Industry, in conjunction with Step Change in Safety, and OPITO has also developed an introductory training programme that introduces the key safety elements required by all employees offshore.   The course is being delivered by an OPITO approved training establishment.   Training will also be given to current employees within the industry with refresher training being given annually.

 

80.       The challenge for the industry and OPITO now is to sustain training and recruitment programmes through the current downturn, and ensure there is a strong skills base maintained to enable the industry to maintain its capability and be ready to take full advantage of the expected recovery in oil prices and economic activity.

 

 

What are the implications of an ageing existing infrastructure on the security of supplies from the North Sea?

 

81.       The main focus for security of supplies in the upstream industry is on gas, because it is less easily transported from other areas of the world and less easily stored compared to oil. As a result, gas shortages could be felt by consumers much more rapidly than shortages of fuels derived from oil. The following points are therefore directed at gas.

 

82.       There are 36 pipelines supplying gas into the UK; 32 from UKCS fields and 5 from other countries. These pipelines land at 16 reception terminals in 7 separate locations around the coastline. The pipelines typically vary from 16” to 44” to diameter, and can be in excess of 200 miles long. Once onshore, the gas is fed into the pipelines forming the National Transmission System (NTS), and then through local distribution systems to industrial and domestic consumers.

 

83.       For UKCS fields, there are a large number of platforms and facilities that produce gas. These vary from wellhead valves on the seabed, up to large production platforms accommodating 200 people and containing large amounts of equipment. A network of smaller pipelines is used offshore to connect more remote fields into main production or collection platforms (termed ‘hubs’), from which pipelines run to shore.

 

84.       Gas production first started in the UKCS in 1967 from BP’s West Sole field, where the platforms and pipelines are still in operation. The development of platforms and pipelines has continued steadily from the late 1960s to the present day, moving from early infrastructure in the Southern North Sea into deeper water areas further north and eventually to the west of the Shetland Islands. New developments are still taking place in all areas of the UKCS. The graph below shows the number of fields starting production over time:

85.       Many platforms and pipelines were originally designed for a life of 20 to 30 years. Hence a lot of these facilities are now at or beyond their design life. The design life was originally linked to the expected length of production, but this has been extended for many facilities due to better than expected reservoir performance or new nearby fields being connected to the platform. For example, three new fields have previously been connected into the West Sole facilities, and a further two new fields will soon be connected, leading to a further 10 years or more of production from the combined fields.

 

86.       Calculation of a design life has not always been carried out rigorously, typically being based on an assumed rate of corrosion in main equipment items and sometimes crude assessments of the accumulation of fatigue damage in main structures. The actual rate of deterioration depends on many factors, including material and manufacturing specifications, the reservoir fluid composition and condition, the operating environment and the maintenance philosophy. The successful operation of older facilities demonstrates that careful management of all the factors affecting deterioration is the key to extending the design life.

 

87.       It is generally accepted that the low oil and gas prices during the 1990s led to reduced effort being spent on maintenance. This has led to increased ‘downtime’ of offshore facilities, and was one of the main drivers for DECC to start the Stewardship initiative for producing fields in 2004. At around the same time, the Health and Safety Executive (HSE) started a Key Programme on Asset Integrity (KP3) on the basis of similar concerns.

 

88.       The HSE report on KP3 was publicly released in 2007 and described a number of difficulties with maintenance management systems and overall condition of infrastructure. However, it also concluded that some of the main components of platforms (main hydrocarbon boundary, jacket and primary structural integrity) were reasonably well controlled. Industry has responded positively to the challenges laid down in the KP3 report, and the indications are that maintenance activity has increased in recent years as a result of this programme and the DECC Stewardship initiative.

 

89.       The table below summarises the contributions of various pipelines to UK gas supply, grouped by terminal. The percentage contributions are averaged for the 2008/09 winter to date.

Summary

 

90.       It is possible for offshore infrastructure to be operated successfully beyond the notional design life, provided that this is properly resourced and managed by the operators.   DECC and other regulators are seeking to ensure that this takes place.   There is significant diversity and robustness in the arrangements for gas supply from the UKCS and abroad.   DECC is continuing to work with industry to better understand and improve where possible the resilience of gas supply arrangements.

 

 

Is the right policy framework in place to manage the decommissioning of that infrastructure as resources are depleted?

 

91.       The Government has a responsibility to ensure that all offshore installations and pipelines are decommissioned with regard to safety, environmental, social and economic impacts.  DECC manages a decommissioning regime that addresses these factors and conforms to international commitments and public expectations, whilst minimising the risk that the taxpayer might have to step in if companies default.  Legislation has been updated to take account of changes in industry practices and the growth of smaller players in the sector.  DECC balances the national interest in maximising oil and gas activity and  use of the offshore infrastructure against the responsibility for ensuring effective decommissioning.

 

Legislative background

92.       Oil and gas decommissioning is regulated by Part IV of the Petroleum Act 1998, as amended by the Energy Act 2008.  Notices setting a decommissioning obligation on all the companies responsible for an installation or pipeline are served at the start of field life.  If interests change hands, the new company is given an obligation notice and we release the selling party from their liability, if the risk is acceptable.  Towards the end of field life the companies are asked for a decommissioning programme which must be approved by the Secretary of State.  The parties are then responsible for carrying out the work specified in the programme.

 

93.       Obligations to carry out an approved programme are joint and several.  If one party defaults the other companies must pay the defaulting party’s share.  This is an important concept and helps mitigate the risk and protect the taxpayer in a potential default situation.

 

Decommissioning scope and programmes

94.       The industry has begun to decommission the 500 installations and 35,000 kilometres of pipelines on the UKCS but with UK oil and gas continuing to supply around 70% of our prime energy demand, decommissioning work will be spread over the next 40 or more years.  The cost of this work is currently estimated at £23 billion with individual installations costing from £5m to £300m.

 

95.       It is important that this ongoing decommissioning work is carried out in a sound manner consistent with our international obligations.  The OSPAR Convention came into force in 1998.   Ministers adopted a binding Decision, OSPAR Decision 98/3, to ban the disposal of offshore installations at sea.  The Decision recognised there would be difficulty in removing the ‘footings’ of large steel jackets weighing more than 10,000 tonnes and in removing concrete gravity base installations.  As a result derogations may be granted in these cases.  But there is a presumption that all installations will be removed entirely and exceptions will only be granted if an assessment and consultation process shows that there are significant reasons why leaving in place is preferable to re-use, recycling and final disposal on land.

 

96.       The OSPAR Decision is the principal international ruling regarding decommissioning and in the majority of cases installations will be brought on land for recycling and waste disposal.  However, DECC is keen to encourage the re-use of facilities e.g. for other oil and gas developments, gas storage, renewables or carbon sequestration and companies have to consider these options in their plans.  The Energy Act 2008 extends the oil and gas decommissioning regime to offshore gas storage and carbon sequestration projects.

 

97.       Decommissioning programmes need to consider the safety, environmental, social and economic impacts of a project.  All programmes must include an environmental impact assessment which addresses the impact on climate change by detailing potential emissions and consumption of natural resources and energy.

 

98.       Transparency and openness is an important aspect of the regime and DECC consults other departments and agencies and requires companies to consult the public; the outcome of the consultation must be reported in the programme before approval by the Secretary of State.

 

99.       DECC publishes comprehensive guidance notes explaining its policies, the programme approval process and the factors that companies should consider.  The notes were revised in January to take account of comments from industry and clarify how the new Energy Act provisions will be implemented.

 

Changing industry practices and update of legislation

100.     The Petroleum Act 1998, which consolidated earlier legislation, was drafted over 20 years ago when most fields were in the hands of the oil majors.  Since then the majors have sold many assets to independents and smaller companies, which have also developed new fields.  These companies have fewer financial resources than the majors and bring an increased risk that they might not be able to meet their decommissioning liabilities.  New business models and commercial arrangements have also meant it has not always been possible to share liabilities equitably between all the companies responsible for an installation or pipeline because of the wording of the legislation.

 

101.     The Energy Act 2008 addresses these issues by closing a number of gaps in legislation and giving the Secretary of State power to require financial guarantees whenever he believes that the risk to the taxpayer is unacceptable.  Prior to the Energy Act the Secretary of State could only require guarantees to be provided once a decommissioning programme had been approved and programmes are only developed towards the end of field life when there is a clear understanding of technical abilities and legislative requirements.  The Energy Act enables new projects to go ahead with the assurance that the taxpayer will be properly protected.

 

102.     There was full and open consultation with industry and other interested parties on the new legislation and where possible, industry concerns were accommodated.   In particular, the Act clearly specifies which licensees can be given a decommissioning obligation, addressing an issue created by the way that licence partners divide their interests under commercial agreements.  DECC continues to work closely with industry to ensure we understand their concerns and our requirements remain fit for purpose.

 

Risk assessment

103.     DECC uses a transparent risk assessment process to determine the risk of companies defaulting on their decommissioning obligations.  This assessment process supports decisions whether to require financial guarantees for new projects when licence interests change hands or when company circumstances change.

 

104.     The costs of decommissioning the installations for which a company is responsible are compared to the net worth on its balance sheet.  We look at all the company’s UKCS interests and the strength of any corporate group to which they belong.  Given the current financing climate, we also look at cash flow and debt repayment data.  If the costs of the project, or the company’s UKCS liabilities, are more than 50 per cent of the net worth, DECC will discuss the situation with the company to confirm its assessment. 

 

105.     If the assessment indicates a medium or high risk we will check if the company has a parent or other associate which has sufficient assets to cover the decommissioning costs.  Decommissioning obligations can be placed on the associated company to spread the risk.  If the risk cannot be mitigated, DECC will require a financial guarantee after first giving the company an opportunity to make representations, and consulting the Treasury on any implications for tax.

 

106.     Security can be cash or bank guarantee such as a letter of credit.  Guarantees need to be from a suitably rated financial institution and the current down grading of banks and reluctance to lend money restricts industry options.  DECC recognises this and invites alternative forms of security whilst ensuring our requirements remain proportionate.  Despite the increase in smaller companies operating in the UKCS, financial guarantees have only been necessary in a minority of developments and security costs are not a significant element in project budgets.

 

Summary

107.     DECC operates an efficient regime ensuring sound decommissioning is carried out in a manner consistent with the UK’s international obligations and public expectations.  A flexible approach enables decommissioning policy to take account of industry concerns and the open and transparent process ensures stakeholder access.  The risks of company defaults are monitored and assessed throughout field life and mitigation measures instigated if the risk to the taxpayer is unacceptable.

 

108.     DECC recognises the impact of liabilities on trading of licence interests and future developments and works with the industry to minimise any restriction on future oil and gas activity.  DECC recognises the opportunities for re-use of structures for other energy or climate benefits.  The Energy Act 2008 has updated the decommissioning regime to meet the requirements for future oil and gas activity. Clear guidance and a transparent risk assessment process help companies understand their position.  This is particularly important as Government and industry cope with the impact of the banking crisis and the current low oil price.

3   Higher oil prices and technological developments could also increase the extent to which existing discoveries are commercial; improved geological knowledge can also affect the estimates of the commerciality of existing discoveries. To date, recent increases in oil and gas prices have not resulted in a significant reclassification of the status of existing uncommercial discoveries to probably or possibly commercial; some reclassification has occurred but the extent has been masked by downgrading of reserves for technical reasons.
