Cross Faults - A Major Control on Lateral Compartmentalization of Hydrocarbon Reservoirs of Kuwait

Significant variations in production behavior of the hydrocarbon reservoirs were observed in Kuwait. Understanding of these variations is of vital importance for exploration and production of hydrocarbons. In a synergistic approach, geological, gravity, magnetic, seismic, geochemical and production data were integrated to decipher the reservoir behavior by understanding the structural architecture and role of faults in reservoir compartmentalization. Significant variation in initial reservoir pressures and oil properties across the major cross faults are suggestive of their sealing nature. These faults have developed after the peak oil migration from the Jurassic and Cretaceous source rocks.
