This book represents an integrated geophysical study for the farafra area, Western desert, Egypt including a general review for the different geological data and studies carried out over this area, followed by the petrophysical analysis for Ammonite-1 well which is the nearest well for this area, then the interpretation of the allowed seismic reflection data by picking of four different sequence boundaries and ting them with the well data, finally we used the aeromagnetic and gravity data to determine the depth to basement and detect the different basin locations.
