The Abu Gharadig basin is one of the most prolific basins in the northern part of the Egyptian Western
Desert. It has attracted the attention of geologists and geophysicists for oil and gas exploration. The rock
units studied are the Khoman, Abu Roash and Bahariya formations in the Abu Sennan concession area,
Northern Western Desert. Here, the structural features in the studied area are determined using the
available seismic sections and well logs data. The sonic logs data are used for the determination of the
average and interval velocities in the form of a number of two-dimensional plots and gradient maps of the
studied formations. A number of isochronous maps (two- way time maps) are drawn for the tops of
Khoman, Abu Roash and Bahariya formations and geoseismic cross sections are also constructed. Folds
(anticlines and synclines) and faults (dip-slip) are identified on these maps either individually or in groups
giving rise to step-like belts as well as graben and horest belts.
