Section 1-2 of the Norwegian Petroleum Act sets out that petroleum resource management: shall be carried out in a long-term perspective for the benefit of the Norwegian society as a whole. In this regard the resource management shall provide revenues to the country and shall contribute to ensuring welfare, employment and an improved environment, as well as to the strengthening of Norwegian trade and industry and industrial development, and at the same time take due regard to regional and local policy considerations and other activities. Other states use different words to describe their aims, but in substance most would agree that the description above captures the overall purpose of petroleum resource management. The greater challenge is how to achieve those aims. Different models are applied from country to country depending on the societal, political, economic and legal context.
