Abstract
The PhD thesis is a collection of four articles that investigate the controls of syn- and post-kinematic faulting on reservoirs. Case studies from the Barents Shelf are presented (Svalbard and the Hammerfest Basin). Offshore seismic studies detail the tectono-stratigraphy of the Goliat field with emphasis on genesis of the Goliat structural closure and fault influence on the deposition of the Late Triassic Realgrunnen Subgroup. Onshore Svalbard (central Spitsbergen), Late Triassic – Early Jurassic successions are appraised as potential CO2 storage units by detailed investigations of sub-seismic structural discontinuities. The controls and styles of growth faulting are investigated by studying Mid-Late Triassic growth faults on east Svalbard (Kvalpynten) where a tectonic triggering mechanism is envisaged to instigate collapse of a counter-regional slope induced by differential compaction.List of papers
