Triassic Channel Systems on the northern Loppa High, SW Barents Sea
During the Triassic, the Barents Sea Basin was filled with sediments from the Uralian and Caledonian mountain belts. High sediment yield and large river systems made progradation possible, resulting in an alluvial to deltaic plain stretching from the mountain belts in the south east to Spitsbergen i...

During the Triassic, the Barents Sea Basin was filled with sediments from the Uralian and Caledonian mountain belts. High sediment yield and large river systems made progradation possible, resulting in an alluvial to deltaic plain stretching from the mountain belts in the south east to Spitsbergen in the north.This thesis focuses on the northwestern part of the Loppa High area, SW Barents Sea. The aim of this study is to further understand channel development in the Triassic, which is of great importance in hydrocarbon exploration. Channel systems can act as a repository for coarse-grained sediments, and hence represent promising hydrocarbon reservoirs.This study is based on the 3D seismic dataset WIN12003 together with logs from exploration well 7224/2-1.
