HC Deb 30 June 1981 vol 7 c317W
Mr. Gordon Wilson

asked the Secretary of State for Energy how many drilling companies in the Scottish sector of the North Sea are United Kingdom or foreign owned.

Mr. Gray

There are currently 18 drilling companies on the United Kingdom continental shelf, including oil companies drilling in their own right. Of these, six are either wholly United Kingdom owned or companies in which there is a substantial United Kingdom equity interest.
