Agat field is a gas condensate field located 50 km west of the Norwegian coastline in the northeastern part of the North Sea. The field is located on a subplatform between the Fennoscandian shield and the Sogn graben. The reservoir consists of submarine sand lobes of late Albian age. Agat was the first field that proved hydrocarbons in the Lower Cretaceous sequence, offshore Norway. The sand is assumed to be transported by sediment gravity flows from the east with the Fennoscandian shield providing the source area. The gas is probably generated from Upper Jurassic shales in the Sogn graben to the west. Owing to limited possibilities for defining the reservoirs on seismic data, the field has been difficult to map. Four wells have been drilled from 1976 to 1982, of which two have tested gas. The two discoveries, however, are not in pressure communication and hence belong to different sand lobes. Total reserves are estimated at 500 bcf gas-in-place. The license was relinquished in 1988 by the operator, Saga Petroleum and its partners, Statoil and British Petroleum, because of poor field size definition as well as economic considerations.
