Title: Diagenetic Trends in Arid Carbonates: What Makes the Khuff Dolostone Reservoirs?
Abstract: Numerous studies and publications have shown that the Khuff reservoirs in the Middle East consist of carbonates that were deposited on shallow, hypersaline epeiric platforms. Hypersaline deposits are represented by evaporites, whilst carbonates correspond to the more open-marine conditions. The availability of diagenetic hypersaline brines favoured dolomitization and precipitation of anhydrite cements. Thus, a significant percentage of the Khuff Formation contains dolostones, which were formed during early diagenetic stages (sabkha and/or reflux dolomitization) and during burial (burial dolomitization and fault/fracture-related dolomitization).
