Written by the leading expert in the history of UK energy, this study provides new, in-depth analysis of the development of UK petroleum policies towards the North Sea oil and gas industry from the early 1960s to the early 1980s. Following on from volume I (The Growing Dominance of the State) to discuss the more recent history of the North Sea oil and gas industry, here Alex Kemp offers new insights into developments in the industry. The controversial decisions to raise gas prices to consumers and to introduce the Gas Levy are discussed, while the thinking behind the gradual reduction in taxation - including the abolition of SPD (Supplementary Petroleum Duty) and the removal of royalties on new developments - is fully explained. The various options considered to reduce the powers of BNOC (British National Oil Corporation), then privatise its upstream assets, and finally to abolish the state company altogether are fully discussed, as is the thinking leading up to the privatisation of the British Gas Corporation in 1986.This volume also sheds light on the development of policies onshore, particularly the role of the OSO (Offshore Supplies Office), and the response of British industry to the North Sea opportunity. Finally, the evolution of policies relating to health, safety, decommissioning, and the environment over the whole period of the study are examined. The Official History of North Sea Oil and Gas will be of interest to students of North Sea oil and gas, energy economics, business history, and British politics, as well as to petroleum professionals and policymakers.
