Abu-Madi Formation in Baltim Field, offshore Nile Delta deposited as fluviomarine environment
which exhibits complex lithofacies. It is composed mainly of sandstone intercalated with siltstone and shale interbeds.
Facies analysis and reconstruction of facies patterns for Abu-Madi Formation were performed using Log curve shapes
techniques. Vertical profiles of borehole log data against sand intervals of Abu-Madi Formation define the history of
deposition and the different genetic rock types. Three rock genetic types were identified indicating deltaic
sedimentation. They are: 1. Braided stream, 2. Mouth bar deposits and 3. Meandering channels. These rock genetic
types are considered as the main gas producing zones in the Baltim Field
