Abstract

The main objective of this context is to delineate and map Abu Madi Formation which is the main reservoir in this study area in Baltim gas field located in the Nile Delta to evaluate the hydrocarbon (gas) potentiality in this field and study the reservoir properties based on the available seismic data.
Baltim field comprises two reservoir levels named III main and III lower within the Upper Messinian Abu Madi Formation.
The seismic interpretation started with creating the synthetic seismogram which is used for the well to the seismic tie followed by picking the desired horizons in all the provided 2D seismic lines, then two-way time maps were generated for each top of these reservoirs after that the average velocity calculated from the time-distance curves acquired from the check shot data are used to provide the structural depth maps to study the areal extension.
Finally, depth-structure contour maps are constructed to enhance the hydrocarbon productivity based on the interpretation of the available seismic data.
