The Oil & Gas Authority estimates the UK Continental Shelf’s proved and probable reserves as of Dec. 31, 2017, were 5.4 billion boe, which could sustain production for at least another 20 years or more based on current production rates. The report said 400 million boe were added to the categories of proved and probable reserves during 2017. About 600 million boe was produced, which equates to a reserve replacement ratio of 69%.
