Abstract
The aim of this research is determining how to use the modern seismic techniques for tracing and
determining the hydrocarbon accumulation in Kafr El-Sheikh Formation (Pliocene age) in the western part of South
Batra field, Nile Delta –Egypt, by making 3D seismic interpretation to understand the structure setting and to configure
the minor structural elements. This interpretation is made by tying the logs with the seismic data. The output is time
structural map, by using the wells to eliminate the velocity model the depth conversion had been done.
From the AVO (Amplitude Variation with Offset) analysis and by using the wells data,it is clear that South Batra field is
a class III AVO (Increase of negative amplitude with offset).
By using the post-stack seismic inversion to delineate the hydrocarbon reservoir, it facilitates the interpretation of
meaningful geological and petrophysical boundaries in the subsurface. The inversion is an inverting the relative
acoustic impedance values from the seismic to an absolute acoustic impedance values.
