Abstract

In CO2 underground storage operations major concern need to be directed at the integrety of the caprock. In the Sleipner Field in the Norwegian North Sea CO2 is separated from the rich gas of the Sleipner Vest Field and disposed at 800-1100 m depth in an underground aquifer that is capped by a thick shale sequence. The shale-sand formation has not been buried to greater depths and the shale can thus be taken as an example of a shallow caprock that may well have properties very different from deeper seated caprocks known from petroleum reservoirs. Previous work have characterized the weakly consolidated caprock by indirect means; in this study reservoir condition experiments on fresh caprock samples aim at determine capillary entry/break-through pressure and in-situ poroperm properties of the Nordland Shale caprock.
