HC Deb 17 April 1978 vol 948 c30W
Mr. Wm. Ross

asked the Secretary of State for Energy how long he expects natural gas supplies from the North Sea to last.

Dr. Mabon

On present estimates of ultimately recoverable reserves and of future depletion rates North Sea gas is expected to be available for some time beyond the end of the century, but the quantities are likely to decline towards the end of that period.
