Abstract

A miscible gas injection project has recently been sanctioned for the Wytch Farm Sherwood reservoir. Commencing during the second half of 1997, a total of 23mmscfpd of miscible gas will be injected into five wells in a Water AIternating Gas cycle, sweeping the reservoir through inverted nine-spot patterns. The project will be extended to a further five patterns over a ten year period to cover almost 50% of the reservoir. It is predicted that an incremental 12.6mmstb of oil reserves will be produced, but losing 10.6Bscf of sales gas and 443mtn of LPG to the reservoir.
