dc.description.abstractSeal integrity is a key property for petroleum exploration. This is even more the case in uplifted basins, as exemplified by the northern Barents Shelf. Uplift may lead to fracturing, decompaction, gas expansion and fluid flow. Therefore, it is critical to understand the mechanical behaviour of the Jurassic shale caprocks in the Greater Hoop area, where hydrocarbon accumulations are situated as little as 250 m below the seabed. In this contribution we study the Upper Jurassic Fuglen and Hekkingen formations. We analyse the mechanical properties of six wells in the study area in combination with leak-off tests and 3D seismic data to characterise the caprock variability over the area. Ductility appears to be largely a response to total organic content, with overall sealing properties appearing exceptionally good in southern parts but diminishing to the north in the study area due to increasing silt content and thinning of the more organic rich Hekkingen Formationen_US
