Khuff formation Permian-Triassic carbonate in the Qatar-South Fars arch hydrocarbon province of the Persian Gulf

摘要

Since the 1948 discovery of prolific gas reservoirs in Bahrain, Middle East explo-rationists have been interested in the Khuff Formation (Permian-Triassic carbonate). Several supergiant gas fields (reserves above 10 tcf) have been found in the region. North of the Persian Gulf very large gas fields have been discovered in Permian strata of south Iran, especially in coastal Fars, such as Kangan, Dalan, Nar, Aghar, Bandubast, Mand, Varavi, Asaluyeh, as well as in the Persian Gulf (Fig. 1). Qatar-South Fars province contains light and heavy crude oil ( Bashari, 1988), in addition to being one of the most important gas provinces in the world (Fig. 1).
