Seismic imaging of faults and sedimentary systems of the Hoop region, Barents Sea: Seismic facies, fault geometries and detection thresholds

In this doctoral thesis, geophysical and geological data are combined with seismic modelling to explore how structures and sedimentary systems in the subsurface can be imaged and mapped. Seismic data of different resolution, tied to borehole information, from the Hoop area in the southern Barents Se...
