Abstract
The Khuff Formation represents an intra-Late Permian, Tatarian transgression over a varied topography in Kuwait. The formation occurs at greater depth in comparison to adjoining regions and is fully penetrated only in the wells located over the Kuwait Arch. The formation comprises mainly dolomudstone, foraminiferal and algal dolowackestone, peloidal and algal dolopackstone, peloidal and oolitic dolograinstone, anhydrite and minor limestone deposited in evaporitic low energy inner to middle ramp setting. Dominantly supratidal to subtidal, restricted setting and hypersaline conditions were prevailing during the deposition. Dolomitization has caused rare development of intercrystalline porosity, however mostly over dolomitization coupled with anhydrite cementation has deteriorated the porosity.
