Diagenesis and Geology of the Sarvak Fm. Reservoir, Dehluran Field, SW Iran; a Case Study

P047 DIAGENESIS AND GEOLOGY OF THE SARVAK FM. RESERVOIR DEHLURAN FIELD SW IRAN; A CASE STUDY Abstract 1 The middle Cretaceous Sarvak Formation is one of the best reservoir units in Southwest Iran. In the Dehluran Field the Sarvak Formation is divided into two parts separated by pelagic deposits. The upper part forms the recoverable hydrocarbon reservoir and was deposited in middle Cenomanian-early Turonian age. Three main sequences have been recognized: US1 US2 and US3 from base to top. US1 grades from intrashelf basin deposits in the lower part to shallow shelf in the upper part. US2 and US3 both
