UK oil and gas reserves
DECC aggregation of UK reserves and resources as at the end of 2012 is based on data collected from operators during February and March 2013.
In total, 748 fields and potential developments or past discoveries – both offshore and onshore – were reviewed.
Information about the data
- analysis in the oil and gas tables is focused on remaining reserves instead of estimated ultimate recovery.
- the UK reserves tables are presented in metric units but Appendix 1 shows field unit versions of these tables.
- the overall summary page presents tabular figures for discovered resources only, and offers an explanatory paragraph that takes account of the estimates for undiscovered resources to arrive at a best estimate of remaining recoverable UKCS hydrocarbon resources.
- the summary table is presented in billion barrels of oil equivalent (boe) to allow comparison of oil and gas data.
- Appendix 2 shows historic UK oil and gas reserves and production figures and is the data used to generate the oil and gas reserves v time charts

Terms
Term
Definition
Estimated ultimate recovery
Total recovery from a field, i.e. reserves plus past production
Reserves
Discovered, remaining reserves that are recoverable and commercial. Can be proven, probable or possible depending on confidence level
Potential additional resources
Discovered resouces that are not currently technically or commercially producible
Undiscovered resources
Undiscovered potentially recoverable resources in mapped leads
Reserves are categorised as ‘proven', ‘probable' or ‘possible', based on confidence levels, as follows:
Reserves
Description
Proven
Reserves that on the available evidence, are virtually certain to be technically and commercially producible, i.e. have a better than 90% chance of being produced
Probable
Reserves that are not yet proven, but which are estimated to have a better than 50% chance of being technically and commercially producible
Possible
Reserves that at present cannot be regarded as probable, but which are estimated to have a significant – but less than 50% – chance of being technically and commercially producible
This data was published in August 2013 and due to be updated in September 2014.

Oil discharged with produced water
A mixture of oil, water and gas is produced from reservoirs and these components are usually separated in the production train. The oil and gas is exported to shore while the produced water is disposed of. Produced water can be disposed of in a number of ways, however it is most commonly discharged to sea. The produced water will be contaminated with oil and is therefore treated to remove the majority of oil before being discharged to sea – although small volumes remain.
Legislation
Between 1991 and 2005, the discharge of oil-contaminated produced water from offshore installations was permitted by an exemption granted under the Prevention of Oil Pollution Act 1971 (POPA). The oil content can not exceed 40 parts per million as a monthly average.
The Offshore Petroleum Activities (Oil Pollution Prevention and Control) Regulations 2005 (OPPC) came into effect on 20 August 2005, replacing POPA. Under OPPC, installations are granted a permit for activities discharging oil to sea.
Since 1 January 2006, the oil in produced water must not exceed 30 milligrams per litre as a monthly flow weighted average.
In 2001 the OSPAR (Oslo and Paris) Convention for the Protection of the Marine Environment of the North-East Atlantic – to which the UK is a contracting party – adopted Recommendation 2001/1. The recommendation set a goal that “each Contracting Party should ensure that the total quantity of oil in produced water discharged into the sea in the year 2006 from all offshore installations under its jurisdiction has been reduced by a minimum of 15% compared to the equivalent discharge in the year 2000 for all offshore installations under its jurisdiction at that time”.
The UK oil and gas industry implemented improvements in produced water management, which resulted in the UK meeting and exceeding the 15% reduction set under OSPAR Recommendation 2001/1.
