Monthly Lecture

David Alsop (Subject Matter Expert, Shell) will talk about:

Dryland vs humid tropical fluvial systems in the Gharif Formation, Sultanate of Oman.

The Permian Gharif Formation in Oman comprises three main depositional units, The Lower (LG), Middle (MG) and Upper Gharif (UG), each of which has a different depositional setting. The LG was deposited in a transgressive to early highstand marginal marine shoreface and deltaic setting following the Permo-Carboniferous Al Khlata glacial deposits. The MG transitions from a progradational deltaic environment to semi-arid fluvial depositional system. Deposition in the MG ended an unconformity related to the breakup of Gondwana with an estimated 5-10 Ma age gap prior to deposition of the Lowstand UG which was deposited in a humid fluvial system.

In this talk, the differences of the MG and UG depositional systems will be investigated as well as their impact on depositional geometries, reservoir architecture, connectivity, and reservoir properties.
