HC Deb 29 October 1979 vol 972 c379W
15. Mr. Jessel

asked the Secretary of State for Energy how long he expects the stock of North Sea oil to last.

Mr. Gray

The current estimate, as published in the 1979 Brown Book, is that recoverable oil reserves originally in place on the United Kingdom continental shelf lie between 2,400 and 4,400 million tonnes. Production from the UKCS is expected to continue into the twenty-first century.
