Geophysical Evaluation for Wadi Rayan Field, Western Desert, Egypt

Wadi Rayan Field is located approximately 115 km from Southwest Cairo. The study area is a platform lying between Abu Gharadig and Beni suef basins. It was discovered in September, 1996 through drilling well WR-1x which has been drilled to a total depth of 7740 ft. in basement. Abu Rawash G member is Cenomanian in age and the only producing horizon in this area; it’s composed of shale and sandstones intercalations with minor carbonate interbeds. The main producing interval in this member is ARG-5 which consists of sandstone, silt and shale. The thickness is varying along whole study area. It ranges from 1 to 100 ft. There are two intervals of producing sandstone which not only vary from one well to another but also not deposited in some wells. For these reasons, it is important to integrate all available geological and geophysical data to come up with a model for ARG reservoir.
