Application of 3D Static Modeling and Reservoir Characterization for Optimal Field Development: A Case Study from the Kharita Formation, Karam Field, Western Desert, Egypt

Kharita reservoir in Karam field is a prolific early Cretaceous reservoir located in Badr El Din concessions, Abu Gharadig basin, Western Desert, Egypt. This reservoir is characterized by lateral and vertical variations in facies type, reservoir quality, and connectivity, which in turn affect the efficiency of further exploitation in the Karam field. Herein, a 3D static reservoir model was conducted using multidisciplinary datasets (well logs, seismic, core, pressure, and production data) to provide a comprehensive understanding of Kharita reservoir characteristics helping optimize the strategies of hydrocarbon field development. The conducted well correlation reveals potentially multiple gas accumulations separated by mappable shales. Two types of reservoir quality were interpreted for the Kharita, good-quality active distributary channels, and poor tidal flat deposits. The different types of genetic facies have different property distribution and connectivity behaviours. Active distributary channels have higher connectivity than the tidally influenced channels and the tidal flat sands. The estimated initial gas in-place demonstrated that half of the gas volume is attributed to poor-quality sands. This work procedure will lead to a more precise prediction of reservoir performance, and select the optimum subsurface development plan, including the location and number of infills required to increase the ultimate gas recovery from the Kharita reservoir in Karam fields.
