Research into the quantification and reduction of geological uncertainty has directly resulted in changes to UK government policy relating to the subsurface as a geological resource. Through Prof Shipton's membership of the Royal Society/Royal Academy of Engineering (Joint Academies) expert working group on risks associated with shale gas extraction in the UK, her research has informed the Department of Energy and Climate Change on ways to calculate and mitigate the risk of seismicity and associated undesirable fluid flow. The Joint Academies report resulted in the lifting of the UK Government embargo on fracking in Dec 2012, allowing exploration for shale gas in the UK to resume, with associated economic and societal benefits of an enhanced UK gas resource. Prof Lunn's membership of the UK Government Committee for Radioactive Waste Management (CoRWM) (2008-present) has resulted in her research informing the substantial changes made to the siting policy for UK radioactive waste disposal from February 2013.
Bristol researchers have been working with the oil and gas industry to develop new methods for monitoring and modelling deformation in oil and gas reservoirs. Industry and NERC funded research has led to the development of (i) novel techniques that better utilise microseismicity monitoring of petroleum reservoirs, and (ii) new software which couples geomechanical deformation and fluid flow with geophysical observations. The research has led directly to development and improvement of commercial software to enhance exploration efforts and minimise costs. Bristol software is now used by several multinational companies worldwide and its development has led to a successful start-up company.
Impact: Economic benefits have been derived from the MTEM Limited spin-out company, which has been owned since 2007 by Petroleum Geo-Services (PGS). These include a commercial marine application of the MTEM (Multi-Transient ElectroMagnetic) method offshore Tunisia in 2008, successfully discovering hydrocarbons before drilling and the 2012 launch by PGS of a fully-towed commercially-viable marine MTEM system.
Significance and reach: Approximately 180 man-years of employment, with a value of more than $15M, have been provided in Edinburgh over the period January 2008 — December 2012.
Underpinned by: Research into electromagnetic survey methods, undertaken at the University of Edinburgh (1999 onwards), which led directly to the creation of MTEM Limited.
ERPE research led to the following impacts in the REF2014 period:
Failure to predict and control geological overpressures during drilling can lead to operational delays costing millions of pounds, or to blow-outs causing serious environmental damage and costs running into billions. Using methodologies, knowledge and data analysis techniques developed at Durham, a spin-out, GeoPressure Technology (GPT; now Ikon Geopressure) (20 employees, revenues 2008-13: £10.8 million) has become a niche supplier to the global oil industry of expertise, training and software ("PressureView") that predicts and assess the causes of overpressure. GPT consultancy has had particular impacts for companies drilling in the North Sea, offshore Canada, Norway and West Africa where overpressure represents a significant technical challenge.
Researchers in petroleum geology at the University of Aberdeen have since the mid 1990's been investigating the characteristics and geological context of sand injectites. The geological contexts within which injected sands are discovered have permitted a step change in the production potential in some oil fields (up to c. 1 billion barrels oil), and to define new exploration targets (up to 250 million barrels oil) to make a significant increase to the overall proven reserves of hydrocarbons in any given province (e.g. the North Sea). The findings of this research have been utilised by a number of multinational oil & gas companies to optimise their exploration and field development strategies to maximise the commercial production of hydrocarbons. This case study describes the economic impacts resulting from two projects in particular in the North Sea, the Volund field (Marathon Oil) and the Mariner Field (Statoil) resulting in the enhancement of strategy, operations and management practices; improvements in performance and adoption of new processes; and creation of new employment as a direct result of research facilitating the development of new assets that would otherwise have remained fallow.
Research performed at the University of Leeds allows the petroleum industry to reduce radically the amount of time that taken to estimate the key properties of tight sandstones containing natural gas. These properties largely determine whether gas fields are economically viable. Tests used in the past have taken between six months and two years to complete; with the Leeds research, results can now be obtained in less than one day — a radical improvement. Industry has used the results to justify drilling new prospects and to improve understanding of the controls on gas and water production in existing fields, which has shaped appraisal and production strategies.
Since Prof Blunt's appointment as a Professor of Petroleum Engineering at Imperial College in 1999, his Consortium on Pore-Scale Modelling has developed numerical tools to analyse the pore spaces of reservoir rocks, predict multiphase flow properties and determine field-scale impacts on oil recovery. This technology is now exploited by at least two start-up service companies with annual revenue of around $20 million, and is widely employed by major oil companies, leading to better reservoir management and improved oil and gas recovery. Statements submitted from just one company (Kuwait Oil Company, KOC) suggest a benefit of $100 million from efficiency savings and improved recovery in a just single field.
Research by the University of Aberdeen's research group on Stratigraphic Evolution of large Igneous Provinces (StratLIP) has guided the successful development of new oil-producing fields in the North East Atlantic that were previously not in production, aided by an improved understanding of the geological context within which the reserves were discovered. The research has informed every phase of exploration and development by several of the UK's leading energy companies, in one project saving the partners £600m and proving the financial viability of a major oilfield development deemed important to the UK's oil supply. The findings have contributed to an increase in the UK's energy security and the strength of the UK's oil and gas industry, especially in the context of the local economy of Aberdeen, the energy capital of Europe.
Kimberlite research at Bristol has been a collaborative enterprise with De Beers over the past 10 years. The research investigating the geology of kimberlites, and understanding the processes that form them and their associated diamond deposits, has clarified their importance to the diamond mining industry, ensuring high quality geological information informs their commercial activities. The success of this initiative has led to procedures and strategies being changed within De Beers, and led to the mitigation of potential future losses in the form of a decreased risk of failure of a resource model. Typically, such resource models can be valued at between tens and hundreds of millions of pounds.
