Abstract The objective of this study is a multifold one, the main target is to evaluate the Nubia Sandstone as a main reservoir of the October Field, delineate the basement structural framework of the study area as well as construct the Nubia Sandstone structural contour map to spot lighting on any other promising locations for hydrocarbon exploration. One of the most important targets is reprocessing for a selected seismic line to test parameters and try to enhance the seismic data, reducing multiples and clarify the Pre-Miocene events which is the main problem of seismic processing in the study area. This may effectively help the re-evaluation of the Nubia Sandstone in the study area. Moreover, petrophysical parameters are studied to evaluate the Nubia Sandstone reservoir of the main October Field, using the different well logs for the available wells in the area.different well logs for the available wells in the area. To achieve these goals, the geophysical and geological data are used. The seismic data set for a selected seismic line, crossing the main October Field was reprocessed after testing seismic processing parameters and producing the optimum processed one, the potential field (magnetic) data of the study area are also processed and interpreted and magnetic modeling was carried out for selected profiles, one of these profiles is passing through the selected seismic line. Tying one of the magnetic models with the reprocessed seismic line was carried out which gives a good comparison with the Pre-Miocene events. The integration with the geological data are obtained from the available drilled wells, producing fifteen structural cross-sections. Basement structural contour map, as well as, Nubia Sandstone structure contour map, depicting some prospective and promising locations which may have hydrocarbon potentiality and may develop the main field. |
