Depositional and Diagenetic Facies in the Jurassic Arab-C and -D Reservoirs, Qatif Field, Saudi Arabia
Qatif Field is a giant oil field that straddles the northeastern Persian Gulf coast of Saudi Arabia (Fig. 20-1). ARAMCO discovered Qatif in early 1946, after surface geology and gravity surveys had indicated the presence of a major north—south anticlinal structure. Qatif is interpreted as a low-amplitude, “banana-shaped” shear fold, convex westward (Fig. 20-2), which was probably formed by right-lateral displacement along basement faults, and possibly enhanced by deep movement of salt from the Cambrian Hormuz Salt. The structure lies on the eastern side of the Arabian Plate, but well to the west of the intense Zagros Mountains fold belt near the plate boundary in Iran.
