oa Sequence Stratigraphy and Reservoir Development of the Khuff Formation of the Arabian Plate

The Middle Permian (Capitanian) to Early Triassic (Induan) Triassic Khuff Formation is a prolific gas reservoir of the Arabian Plate. It is composed of mainly shallow- water carbonates and evaporates, representing a second-order transgressive- regressive sequence, which is composed of seven third-order composite sequences (KS1-KS7). The maximum flooding surface of Khuff Sequence KS4 (Khuff MFS4 at ca. 258 Ma) is interpreted to also represent Khuff second-order maximum flooding. The transgressive system set of the Khuff second-order sequence starts with Khuff Sequence KS7 and ends at the Khuff maximum flooding surface of Khuff Sequence KS4 (Khuff MFS4). The highstand systems set starts on top of Khuff second-order maximum flooding surface and ends at the Top Khuff Formation (top of Khuff Sequence KS1).
