Sedimentological facies models and correlation of the Kobbe Formation in the Goliat Field compared with outcrops at Sørkapp-Land, Spitsbergen
MetadataShow full item record
Detailed sedimentological and sequence stratigraphical analysis of the Kobbe Formation in the Hammerfest Basin, Barents Sea, and the Karentoppen Member, Spitsbergen, contributes to an increased understanding of depositional processes and sand body geometry. Outcrop studies on the Karentoppen Member and core studies on the reservoir section in the Goliat Field is conducted to better define thicknesses, lateral continuity, and vertical stacking patterns of the sandstone bodies in the Anisian-Ladinian, mid-Triassic facies. Refined facies analyses of the Kobbe Formation reveals a proximal deltaic environment dominantly consisting of an estuarine, tidal-fluvial channel environment. The Karentoppen Member reveals a more distal facies development dominantly consistent of a delta front, shallow marine environment with amalgamated distributary channels as a characteristic feature. Based on this study, a westerly source is consistent with previous study. The two study areas are compared based on the results collected from outcrop studies and core logging and the end product is the analogy between the these studies.
