Oil and gas industry in the United Kingdom
The oil and gas industry in the United Kingdom produced 1.42 million BOE per day in 2014, of which 59% was oil/liquids. In 2013 the UK consumed 1.508 million barrels per day of oil and 2.735 trillion cubic feet of gas, so is now an importer of hydrocarbons having been a significant exporter in the 1980s and 1990s.
98% of production comes from offshore fields and the services industry in Aberdeen has been a leader in developing technology for hydrocarbon extraction offshore. Historically most gas came from Morecambe Bay and the Southern North Sea off East Anglia, but both areas are now in decline. Oil comes mainly from the North Sea Central Graben close to the median line with Norway in two main clusters – around the Forties oilfield east of Aberdeen and the Brent oilfield east of Shetland. There have been recent discoveries in challenging conditions west of Shetland. there were of pipelines linking 113 oil installations and 189 gas installations. The only major onshore field is Wytch Farm in Dorset but there are a handful oil wells scattered across England. There is significant shale potential in the Weald and in the Bowland Shale under Lancashire & Yorkshire, but only a few wells have been drilled to date.
The UK's strengths in financial services have led it to play a leading role in energy trading through markets such as ICE Futures. The price of Brent Crude from the British North Sea remains the major benchmark for the international oil trade, and the National Balancing Point market is the benchmark for most of the gas traded across Europe. The difficult offshore conditions make the UK a high-cost producer; in 2014 the average development cost was $20.40/boe and the operating cost was $27.80/boe for a total of $48.20/boe. In 2014 the industry spent £1.1bn on exploration, £14.8bn on capital investment and £9.6bn on operating costs. Fields developed since 1993 are taxed through an additional corporation tax on profits, in 2014 the industry generated £2.8bn in direct taxes.
Early history
After the Scottish shale oil industry reached its peak in the 19th century, the British government became increasingly concerned to find secure sources of fuel oil for the Royal Navy. This led to a nationwide search for onshore oil during the First World War and a modest discovery of oil at Hardstoft in Derbyshire.The country’s oil resources were nationalised by the Petroleum Act 1934, and a fresh attempt was made to find oil on the UK mainland. The outbreak of World War II accelerated this search and led to a number of wells being drilled, primarily around Eakring in the East Midlands near Sherwood Forest. During World War II over 300,000 tons of oil or 2,250,000 barrels was produced by 170 pumps; and production continued until the mid-1960s.
In the 1950s, the focus turned to southern England where oil was discovered in the Triassic Sherwood Sands formation at, followed by the development of the Wytch Farm oilfield. The link between onshore and offshore oil in the North Sea was made after the discovery of the Groningen gas field in The Netherlands in 1959.
Exploration and appraisal
Drilling
Since 1965, 3,970 exploration and appraisal wells have been drilled offshore on the United Kingdom Continental Shelf. In 2014, 104 new wells and 54 sidetracks were drilled.Over four decades since the 1960s, the industry has spent £58 billion by 2008 on exploration drilling. In 2008, £1.4 billion was spent finding new oil and gas reserves.
Discoveries
In 2008, of oil and gas equivalent were discovered. The average size of the oil and gas fields discovered between 2000 and 2008 was 26 million BOE, compared with an average of 248 million BOE in the ten years from 1966.Production
In 2008, the UK was the 14th largest oil and gas producer in the world. In Europe the UK is second only to Norway in oil and gas production.Oil and gas production from the UK sector of the North Sea peaked in 1999, but the UK remains a substantial producer today. Over the last four decades, 39 billion BOE have been extracted on the UK Continental Shelf. In 2008, the combined production of oil and gas was 1 billion BOE. This represented a fall of 5% compared with 2007, a slight improvement on the decline rate in 2002-2007 which averaged 7.5% per annum.
Role in supplying energy to the UK
As of 2008, just over three-quarters of the UK's primary energy demand was met by oil and gas. In 2008, oil produced on the UKCS satisfied almost all domestic consumption while gas produced in the UK met about three quarters of demand. In 2020, it is estimated that 70% of primary energy consumed in the UK will still come from oil and gas, even upon achievement of the government's target to source 20% of energy from renewable sources. This will be a combination of oil and gas produced domestically and imports. The UKCS has the potential to satisfy 40% of the UK's oil and gas demand in 2020, if investment is sustained.Associated expenditure
Over the last four decades, a total of £210 billion has been invested in developing new resources. In 2008, this figure was £4.8 billion, a 20% decrease since 2006. An additional £147 billion has been spent on producing the oil and gas and in 2008, operating costs were £6.8 billion, an increase on 2007.Tax contribution
Oil and gas production from the UKCS has contributed £271 billion in tax revenues over the last forty years. In 2008, tax rates on UKCS production ranged from 50-75%, depending on the field. The industry paid £12.9 billion in corporate taxes in 2008-9, the largest since the mid-1980s, because of high oil and gas prices. This represented 28% of total corporation tax paid in the UK. It is expected that tax revenues from production will fall to £6.9 billion in 2009-10 based on an oil price of $47 per barrel, providing 20% of total corporation taxes. In addition to production taxes, the supply chain contributes another £5-6 billion per year in corporation and payroll taxes.Employment
In 2008, some 450,000 jobs throughout the United Kingdom were supported by the servicing of activity on the UKCS and in the export of oil and gas related goods and services around the world. The exploration for and extraction of oil and gas from the UKCS accounted for around 350,000 of these; this comprised 34,000 directly employed by oil and gas companies and their major contractors, plus 230,000 within the wider supply chain. Another 89,000 jobs were supported by the economic activity induced by employees' spending. In addition, a thriving exports business is estimated to support a further 100,000 jobs. In January 2013 an Industry Job Site www.oilandgaspeople.com predicted that over 50,000 new jobs would be created within the industry that year as new technology makes marginal fields more viable.Whilst the oil and gas industry provides work across the whole of the UK, Scotland benefits the most, with around 195,000 jobs, or 44% of the total. 21% of the workforce is from South East England, 15% from the North of England, and 12% from the East of England. Each £billion spent on the UKCS supports approximately 20,000 jobs.
Companies database
Set up in 1996, First Point Assessment Limited is the key tool used by oil and gas companies to identify and select current and potential suppliers when awarding contracts or purchase orders. The organisation operates as a neutral, industry-steered organisation, improving efficiency in the oil and gas supply chain. FPAL currently matches the needs of over 70 purchasing organisations with the capabilities of over 2,400 suppliers.Tax contribution
Jobs in the UK oil and gas industry are highly skilled and well rewarded. 2008 salaries averaged circa £50,000 a year across a broad sample of supply chain companies, with the Exchequer benefiting by £19,500 per head in payroll taxes.Skills and training
Set up in 2007, OPITO supports the efforts and resources that employers throughout the UK are currently investing in workforce development to ensure that the UKCS remains at the forefront of offshore expertise and technology. The organisation allows the industry to consolidate and improve its work in generating and developing the talent needed to sustain the long-term future of the UKCS and export learning internationally. OPITO works with schools, colleges and universities on a shared agenda of encouraging greater uptake of mathematics, science and engineering subjects. The organisation also supports the development of safety, technical and leadership skills within the industry in response to identified need. Training standards and quality assurance on training delivery both here and around the world are also being advanced through OPITO.Technology and innovation
The operating environment in the waters around the UK is harsh and demanding. To overcome the challenges of recovering oil and gas from increasingly difficult reservoirs and deeper waters, the North Sea has developed a position at the forefront of offshore engineering, particularly in subsea technology. Many new oil and gas fields in the UK are small, technically complex and economically marginal. Often recovery from these fields is achieved by subsea developments tied back to existing installations and infrastructure, over varying distances measured in tens of kilometres. Innovative technology is also a critical component in the recovery of reserves from high pressure, high temperature, heavy crude oil and deep water fields.Exports
UK exports of oil-related goods and services have been estimated at more than 0 billion a year in value. This amount is a reflection of how well established the UK's supply chain is internationally. The competence of its people and the quality of its technology, particularly subset, are very much in demand in oil and gas provinces around the world.Industry collaboration
The Industry's Technology Facilitator identifies needs and facilitates the development of new technology to meet those needs through joint industry projects with up to 100% funding available for promising solutions. Since its creation ten years ago, ITF has helped oil and gas producers, service companies and technology developers to work collaboratively, developing 137 technology projects.Health and safety
Safety vision
Set up 1997, Step Change in Safety is the UK based cross-industry partnership with the remit to make the UK the safest oil and gas exploration and production province in the world. Its initial aim was to reduce the injury rate by 50%, which was achieved in 2003. Step Change in Safety's work is now focused in three areas: recognising hazards and reducing risk, personal ownership for safety and asset integrity. Communication between Step Change in Safety and the industry is through elected safety representatives, offshore installation managers and supervisors, safety professionals and company focal points. These individuals are consulted on what needs to be done and are charged with ensuring that the Step Change programme is implemented.Regulator
The Health & Safety Executive is the UK offshore oil and gas industry regulator and is organised into a number of directorates. The Hazardous Installations Directorate is the operational arm responsible for major hazards. A dedicated Offshore Division within HID is responsible for the enforcement of regulations in the offshore oil and gas industry.Statistics
HSE publishes fatal, major and over-three-day injuries as well as dangerous occurrences under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations.RIDDOR does not apply to events that are reportable under the Air Navigation Regulations 1986; the Civil Aviation Regulations 1989; and the Merchant Shipping Act 1988, and orders and regulations made thereunder – therefore, industry-related aviation and marine accidents which are covered by any of the above regulations are not included in the RIDDOR-derived statistics. In 2007/8 and 2008/9, there were no fatalities, compared with two in 2006/7 and 2005/6. During 2008/9, 30 major injuries were reported compared with 44 in 2007/8. This resulted in a combined fatal and major injury rate of 106 per 100,000 workers, down from 156 and 146 in 2007/8 and 2006/7 respectively. The number of over-three-day injuries has fallen this year by 5% to 140, representing an over-three-day injury rate of 496 per 100,000 workers.
Asset integrity
Asset integrity is the ability of an oil and gas asset to perform its required function effectively and efficiently whilst protecting health, safety and the environment. Asset integrity management is the means of ensuring that the people, systems, processes and resources that deliver integrity are in place, in use and will perform when required over the whole lifecycle of the asset. In 2004, the HSE highlighted the infrastructure on which work was required to maintain integrity and £4 billion was subsequently spent in the area of asset maintenance. In 2009, the HSE confirmed that the key issues identified earlier had been resolved. Specific initiatives now encourage industry-wide engagement and continued investment in asset integrity. On a global level, asset integrity continues to be ranked amongst the oil and gas industry's biggest challenges and main focus areas, In spite of this, recent research by Oil and Gas Fundamentals has indicated that understanding of the subject inside the industry is still not where it needs to be.Aviation safety
Aberdeen is the busiest heliport in the UK with 47,000 flights in 2008 transporting workers to and from offshore installations on the UKCS. Between 1977 and the end of 2006, just over 56 million passengers were transported by helicopter from all UK heliports to and from offshore installations on the UKCS. More than 6.5 million sectors were flown, taking nearly 3 million flying hours. During this time, seven fatal helicopter accidents claimed the lives of 94 offshore workers and flight crew. Government data for the period 1995 to 2004 show that with the exception of rail, the yearly passenger casualty rate for offshore helicopter travel is much better than most forms of land-based passenger transport and of a similar order to travelling by car. Offshore helicopter passengers are equipped for their journey with survival suits and other aids and undergo survival training.Other mariners' safety
The Fisheries Legacy Trust Company's main function is to help keep fishermen safe in UK waters. It does this by building a trust fund which can be used to maintain comprehensive, up-to-date information on all seabed hazards related to oil and gas activities for as long as they remain, and to make this data available for use by fishing vessel plotters found on board in wheelhouses all around the UK coastline.Environment
The industry's vision which guides the environmental management process is to understand and manage environmental risks to achieve demonstrable no harm levels by 2020.Atmospheric emissions
UK oil and gas installations participate in the European Union Emission Trading Scheme which aims to reduce emissions of carbon dioxide and combat the threat of climate change. Carbon dioxide is released into the atmosphere in three ways during production operations: combustion of fuel for power generation, flaring and direct process emissions. Over the years, carbon dioxide emissions in tonnes have steadily decreased with a 10% reduction in 2007 compared with 2000. In 2007, 17 million tonnes of carbon dioxide were emitted.Flaring
Open gas flares for well tests are not permitted in the UK. Release of unburned gas is also not permitted by the Environment Agency/SEPA. The low temperature of combustion in open flaring, and incomplete mixing of oxygen means that carbon in methane may not be burned, leading to a sooty smoke, and potential VOC/BTEX contamination. Radon gas exists in very low concentrations in shale gas and in North Sea gas, but the levels predicted fall below any level of concern.In exploration wells, where flow rates are expected to be 10 tonnes of gas per day, testing is licensed by the Environment Agency to 30 days, extendable to 90 days. Enclosed burners are available that will ensure low levels of light pollution, little noise, and 99+% combustion and destruction of VOCs/BTEX, at around 800 C.
Well testing is used to estimate the productivity of the well. In testing a production well, the test can be made by flowing into the production pipeline. This means that no gases would be lost, and flaring would not be necessary. This is known as a 'green completion'.
Marine discharges
Discharges into the sea can occur either through accidental release or in the course of normal operations. In 2007, 59 tonnes of oil in total was accidentally released into the marine environment, which, in open sea, will have a negligible environmental impact.Waste
Types of waste generated offshore vary and include drill cuttings and powder, recovered oil, crude contaminated material, chemicals, drums, containers, sludges, tank washings, scrap metal and segregated recyclables. The majority of wastes produced offshore are transferred onshore where the main routes of disposal are landfill, incineration, recycling and reuse. Drill cuttings are also re-injected into wells offshore.Future of the UKCS
Production
of oil and gas have been produced on the UKCS and up to are left. Therefore, the UK could still be producing significant amounts of oil and gas for decades to come. It is estimated that in 2020, UK production could still meet 40% of the nation's demand for oil and gas.Decommissioning
The principal legislation for decommissioning offshore infrastructure when production ceases is OSPAR Decision 98/3 on Disposal of Disused Offshore Installations. Under OSPAR legislation, only installations that fulfil certain criteria are eligible for derogation. All other installations must be totally removed from the seabed. During the next two decades, the industry will begin to decommission many of the installations that have been producing oil and gas for the past forty years. There are approximately 470 installations to be decommissioned, including very large ones with concrete sub-structures, small, large and very large steel platforms, and subsea and floating equipment, the vast majority of which will have to be totally removed to the shore for dismantling and disposal. Some 10,000 kilometres of pipelines, 15 onshore terminals and around 5,000 wells are also part of the infrastructure planned to be gradually phased out, although some, or parts, of the onshore terminals will remain because they are import points for gas pipelines from Norway and the Netherlands. Decommissioning is a complex process, representing a considerable challenge on many fronts and encompassing technical, economic, environmental, health and safety issues. Expenditure is therefore projected to be £19 billion by 2030, rising to £23 billion by 2040, for existing facilities. New facilities could add another £2-3 billion to the decommissioning cost, raising the total to circa £25 billion.Technology
ExportsThe export of oilfield goods and services developed by the UK over forty years are in demand around the world. In 2008, approximately £5 billion was earned through such exports. As energy demand around the world grows, so too will the need for technology and expertise required to satisfy it.
Transfer to other industries
Marine technology, skills and expertise pioneered in oil and gas are important in the design, installation and maintenance of offshore wind turbines and hence have found roles in the continuing evolution of renewable energy. The industry has led the way in the development of drilling, remotely operated vehicles and geophysical technology. All three areas of expertise are used by scientists and engineers elsewhere, whether examining Antarctic ice core samples, raising sunken ship wrecks or studying the plate tectonics of the ocean floor.
Carbon Capture and Storage
To prevent carbon dioxide building up in the atmosphere it has been theorised that it can be captured and stored, such as the working CCS at the Sleipner field offshore Norway, among other examples. CCS is undertaken by combining three distinct processes: capturing the carbon dioxide at a power station or other major industrial plant, transporting it by pipeline or by tanker, and then storing it in geological formations. Some of the best natural repositories are depleted oil and gas fields, such as those in the North Sea. The oil and gas industry's knowledge of undersea geology, reservoir management and pipeline transport will play an important role in making this technology work effectively.
