Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, pursuant to the Answer of 10 March to Question 161735 on fossil fuels, what proportion of the 10 to 20 billion barrels or more of oil equivalent is classed in the category of (a) 2C contingent reserves and (b) 2P proven and probable reserves; if the Government will make all data on North Sea oil and gas reserves available in the public domain on a field-level basis to support the development of a Global Registry of Fossil Fuels; and if he will make a statement.

The Oil and Gas Authority (OGA) estimate for proven and probable (2P) UK reserves as at end 2019 is 5.2 billion barrels of oil equivalent, and the estimate for the UK’s contingent (2C) resources as at end 2019 is 7.4 billion barrels of oil equivalent.

The OGA does not publish individual field reserves as they are commercially sensitive.
