The study area is located within the southern dip province of the Gulf of Suez rift and includes two oil fields, Al Amir and Geyad. This area is located to the west of Gebel El Zeit and covers an area of about 321 km2. The study is based on the analysis of seismic and borehole data. Six Miocene seismic horizons are mapped from Top Zeit down to top Nukhul Formation. The study area is characterized by SW dip direction and is dissected by major NW-SE oriented, rift-parallel faults and some NE-SW oriented cross faults creating the two blocks of Al Amir and Geyad oil fields. The study shows the effect of these faults on the distribution of the clastic reservoir of the Kareem Formation.
