HC Deb 25 March 1977 vol 928 c700W
Sir J. Langford-Holt

asked the Secretary of State for Energy what basis he uses to compute the amount of gas flared in the northern North Sea fields; and what degree of accuracy he achieves.

Dr. John A. Cunningham

Gas flared in the northern North Sea fields is measured mainly by orifice meters, but a few turbine meters are also in use. The accuracy of gas meters is very difficult to assess but is considered to be within the range of 1 to 2 percentage.
