SLB Petrel is the definitive reservoir simulation platform for upstream operators who need serious subsurface analysis. For GCC carbonate reservoir operators in particular, Petrel's models tuned for Arabian Peninsula geology deliver results that alternatives cannot match. The cloud DELFI subscription has made it accessible to mid-size operators for the first time.
