Abstract
Kangan and Dalan formations are a permo-triasic basin in the Persian Gulf Region which contains four lean-condensate gas bearing reservoir units named as K1, K2, K3, and K4 from top to bottom. These formations, outstretched in a vast area of Persian Gulf region, embedded gigantic reserves of gas condensate mainly deposited in Iran, Qatar, Saudi Arabia, Bahrain, and Abu Dhabi. Kangan/Dalan formations are synonymously called Khuff formation in southern countries of the Region, while in this paper Iranian part of the formations is studied. Litho-typing provides different rock types with specific reservoir and geological properties necessary for geo-cellular modeling. The data required for litho-typing include core data and well logs. To compare the two sources of data. Petro-facies determination was a prerequisite. Permeability prediction is a necessary step of each reservoir characterization and modeling and MRGC method proved to be the best technique to permeability prediction in this study.
