oa Outcrop Analogs of the Oman Mountains Reveal Reservoir Potential in the Triassic Sudair and Jilh Formations (Middle & Upper Mahil, Sultanate of Oman)

Whereas the Permian-Triassic Khuff formation is world famous for its hydrocarbon accumulations in the Middle East, the overlying Sudair and Jilh Formations are mostly top seal or baffle units. In contrast, outcrops in the Jabal Akhdar area of the Oman Mountains (where the Sudair and Jilh Formations are referred to as Middle and Upper Mahil members) consist mainly of dolomites with only occasional thin shale intercalations and reveal potential reservoir facies. While the Sudair is dominated by grainy carbonates of a subtidal shoal setting, the overlying Jilh indicates a restricted supratidal marsh to peritidal/lagoon environment.
