§ Mr. Rostasked the Secretary of State for Energy if he will list those natural gas fields on the Continental Shelf currently in production or under development, their estimated reserves, their estimated years of production, and indicate which are exempted from petroleum revenue tax.
§ Dr. J. Dickson MabonThe fields currently supplying natural gas are the southern North Sea gas fields, West Sole, Hewett, Leman Bank, Indefatigable, Viking and Rough, and the Frigg gas field in the northern North Sea. No other natural gas fields are under development at the present time.
Petroleum revenue tax is not payable on any of these fields.
Confidentiality conditions prevent the disclosure of individual field reserves; total remaining reserves for the above fields—excluding the Norwegian share of Frigg—are 553 billion cubic metres (19.5 TCF). The estimated life of these reserves is 15–20 years.
