Data for oil and gas wells around the UK: production history, income, expenditure on exploration, spills, remaining reserves and approvals.
There are vast amounts of data available that relate to UK oil and gas fields, including historical and current production figures, production projections, charts indicating UK Continental Shelf (UKCS) income and expenditure, and information releases on oil discharges.

UK production data
This is the gateway to the release of UK production data.
The following reports contain data as a rolling 12-month dataset:
Historical production data
- complete production history for oil fields (from 1975) and gas fields (from 1995)
- well data release index page – links to all well production and injection data (up to 1999)

UK Oil and Gas Reserves and Resources
The Oil and Gas Authority (OGA) aggregation of UK reserves and resources as at the end of 2015 is based on data collected from operators during February and March 2016.
In total, 755 fields and potential developments or past discoveries, both offshore and onshore, were reviewed.
The OGA has changed the way we report Reserves and Contingent Resources this year to be compliant with the latest SPE PRMS guidelines
Reserves have therefore been counted for approved and producing fields only. Resources from other significant discoveries where field development plans are under discussion and Extended Oil Recovery (EOR) Potential have been counted as Contingent Resources.
The above change has resulted in a net reclassification of circa 600 million barrels of oil equivalent (mmboe) previously reported as Reserves now being reported as Contingent Resources.
This change has also resulted in some modifications to the way we report Contingent Resources for discoveries in the Summary Table – further details are given in the page referenced below.
Information about the data
- Analysis in the oil and gas tables is focused on remaining reserves.
- UK reserves tables are presented in metric units but Appendix 1 shows field unit versions of these tables.
- 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.
- Summary tables are 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, contingent resources and production figures and is the data used to generate the oil and gas reserves and resources v time charts
|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 (as described below)|
|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:
|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 July 2016 and due to be updated in July 2017.
UKCS income and expenditure
The tables below outline income and expenditure related to exploration, development and operating activities on the UK Continental Shelf:
The tables below list recent oil and gas Field Development Plans Approvals and Field Development Plan Addenda Approvals by OGA in 2015 and 2016 to date.
A full list of offshore field approvals since 1976 is also available together with charts showing the number of new field development plan approvals and field development plan addenda approvals by year and the capex spend committed for these approvals by year.
The tables below list recent oil and gas field start-ups in 2015 and 2016 to date.
A full list of offshore fields in production is also available.
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.
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.
Produced water discharges containing oil (2006-15)
The following table details instances of oil-contaminated produced water discharges between 2006 and 2015.
