The period from 1957-1988 was transformative for the international oil industry. As the home to two major oil companies, BP and Shell, as well as the possessor of large quantities of oil and gas in its territorial waters, the United Kingdom was at the heart of this transition.

While famous for its liberal policy towards oil and gas production, both before and after the discovery of North Sea oil and gas, this period actually saw the United Kingdom respond to shifts in power from the major oil companies to the oil-producing states, many of them in OPEC, by building up its competency regarding oil matters. This took the form of efforts to influence the activities of BP and Shell abroad as well as in creation of a state-run oil company, the British National Oil Corporation, in an attempt to exercise greater state control over oil and gas production and distribution.

The failure of these efforts was driven in part by internal divisions within Whitehall, the efforts of the oil companies themselves, and ultimately the political will of the Conservative Party under Margaret Thatcher to get the state out of the business of oil and gas.
