The first North Sea Oil and Gas Conference was held in Trondheim in 1985 as a part of the Norwegian Institute of Technology's 75th anniversary celebration. Favourable reactions from the delegates prompted the Organizing Committee to rerun the event in 1989. The response was again very encourag ing and led the Committee to conclude that the conference should be held on a regular basis so long as there is a demand for this type of gathering. The third conference in the series was held in 1992. The objectives of the conference series are fourfold: To bring together those who are engaged in various geoscientific and reservoir engineering aspects of North Sea oil and gas reservoirs in one forum; to demonstrate wherever possible the interdependence of the various disciplines and specializations; to promote innovative, synergetic approaches to research and development programmes aimed at North Sea conditions; and to reflect current trends in the reservoir sciences. The conference format has remained unchanged throughout the series. The present conference contained four field reviews by Amoco, Conoco, NAM Velsen, and Statoil, and four keynotes addresses by Professor R. Ewing, Dr. G. Geehan, Dr. D. Johnston, and Dr. F. Santarelli. Twenty-seven research papers were selected from the response to a Call for Papers in accordance with the aims of the conference and their technical contents.

The first North Sea Oil and Gas Reservoirs Conference was held in Trondheim in 1985 as part of the Norwegian Institute of Technology's 75th anniversary celebrations. Favourable reactions from the delegates prompted the Committee to re-run the event some three and a half years later, and it is now intended that the Confe rence be held on a regular basis as long as there is a demand for this type of gathering. The objectives of the 1989 Conference, which were broadly similar to those of the previous one, were: (a) to bring together those engaged in various geoscientific and reservoir engineering aspects of North Sea Oil and gas reservoirs in one forum; (b) to demonstrate wherever poSsible the interdependence of the various disciplines and specializations; (c) to promote innovative, synergistic approaches to research and development programmes aimed at North Sea conditions; and (d) to reflect current trends in the reservoir sciences. Naturally there was no place for specialist parallel sessions in a Conference aimed at encouraging interdisciplinary integration and awareness."
