“…Extensive studies on the reservoirs properties in the KSA have been achieved for hydrocarbon exploration [e.g., Magara et al, 1992;Sail et al, 1998;Koepnick et al, 1995;Hussain et al, 2006;Sahin et al, 2007;Macrides, and Neves, 2008], compiled the results of these studies with the present geological assessments resulted into proposition of the best targets for EOR (i.e., Safaniya oil field (Middle Cretaceous) (Safaniya, Wara and Khafji reservoirs), Manifa oil field (Las, Safaniya and Khafji reservoirs) (Late Jurassic), and Khuff reservoir (Late Permian-Early Triassic)) in central to eastern the Kingdom of Saudi Arabia.…”
