The discovery of hydrocarbon from Jurassic reservoirs and its positive impact on the economy of Kuwait necessitated adopting an aggressive exploration strategy to extend the oil field boundaries beyond the known discoveries in North Kuwait. To cater to this need new prospects are generated by integration of diagenesis and depositional setting with structural configuration and fracture potential of Jurassic reservoirs.

Open-hole log data of 20 wells and nearly 1200ft of conventional cores along with 3D Seismic data form the database of this study. Seven different litho-facies and their probable depositional environment are inferred. The presence of proximal sabkha facies to the hemipelagic basin facies like mudstone, peloidal and oncoidal wackestone, peloidal packstone /grainstone and marls indicate the deposition of Middle Marrat Formation in a micro-peloidal ramp system. The vertical transition of oolitic grainflow facies and turbidites to mudflows to a facies of 50-60’ interval which are more or less slumped indicate the change in the depositional setting of Sargelu to Najmah sedimentation from inner and middle ramp to the outer ramp to basinal environment. The identification of dolomite zone from core and well log found out the extension of dolomitization towards north and northwest. The dolomitization in early diagenetic stage favours the enhancement of porosity which may prevail in Abdali area.
