§ Mr. Ernie Rossasked the Secretary of State for Energy what is his estimate of the net value, in £ sterling, of oil and gas reserves discovered in the North Sea to date at 1981 prices; and what are his Department's projections for this figure for each year up to 1990 at current prices.
§ Mr. Gray[pursuant to his reply, 25 February 1981, c. 376]: The gross value of oil and gas reserves discovered in the United Kingdom continental shelf to date is estimated to be around £400 billion at early 1981 prices. It is not possible to provide figures for the net value of reserves due to the degree of uncertainty about future extraction costs. Projections for the value of reserves at current prices are not available for the period requested.
