Sleipner Øst Field, A Sand-Rich Palaeocene (Ty Formation) Gas-Condensate Reservoir Offshore Norway - Sedimentology, Stratigraphy, Heterogeneity and Paleocontact Influence on Reservoir Properties, Flow and Production

The Sleipner Ost gas-condensate Field (and the minor neighbouring Loke Field) offshore Norway (Fig.1) started production 1 Oct. 1993. The Palaeocene Ty Formation is the main producing reservoir, a structural stratigraphic trap where the gas is reinjected until the year 2005 to keep up the pressure and produce the condensates. At present there are 12 production and 3 injection wells on the Field.
