Structural Framework

Basin Opening in Kimmeridgian -Tithonian times, the rift system is orientated WNW-ESE parallel to ‘Najd Trend’ some NE-SW transfer faults parallel to ‘Gulf of Aden’ faults, major basement depocenters lay in the adjacent hanging walls, salt tectonic affects post salt formations.

A regional dip cross-section from the Mahfid Uplift, through Block-4 and Central Basin High to the Asakir High shows half-graben feature elements. The main structural elements in the Ayad Block are relatively parallel to Basin orientation. three main basement highs (Trends) Central Basin High, Ayad & Amal High.
