Developing Methodologies for Static Reservoir Modelling in a Carbonate Shelf Setting: example of the Early Cretaceous Thamama B reservoir

The studied field is located in the onshore area of the Arabian Peninsula. The trap is formed by a gentle faulted anticline, trending SW-NE, and contains sweet, 39° API crude oil. It was discovered in the sixties in Early Cretaceous carbonate reservoirs, the Thamama Zones B & C. The volume of oil in place (STOIIP) in the field is several billions barrels. Since the seventies, the oil is recovered with water injection schemes including dozens of injector wells and hundreds of producer wells. The current production is exceeding hundred thousand oil barrels per day.
