Post stack seismic inversion is the procedure for extracting underlying model of the physical
characteristics of rocks and fluids. It is used to estimate the physical properties of the rocks by combining seismic and
well logs data. Post stack seismic inversion has proven to be very useful theory in the detection of the hydrocarbon
occurrences and lithological definition in the area of study. Lower acoustic impedance anomaly was very clear
confirming the hydrocarbon occurrences at the zone of interest in our study area which is Alam El Bueib 3G reservoir
member. Also, this approach was very helpful in the detection of higher acoustic impedance anomaly at the level of
Alamein Formation due to the presence of dolomite and shale as seal rocks.
