Geologic setting

The Alwyn field is located in the UK sector of the North Sea, about 440 kilometers northeast from Aberdeen. The geologic setting is a tilted block structure with three reservoir formations (Figure ): the Brent reservoir (top) produces oil, the Statfjord reservoir (middle) produces gas and the Triassic reservoir (bottom) produces oil. Existing 3D isotropic prestack time-migration (PSTM) and prestack depth-migration (PSDM) images are considered insufficient for structural understanding of the different fault blocks of this fluvial formation.
