| Abstract |
| Characterizing (possible) reservoirs is by far the biggest driver of geophysical spending in the exploration and production industry. The straightforward explanation is that fewer wells are necessary for reservoir exploitation due to improved reservoir characterization's greater success rates. Seismic and well log data were combined in this research project to characterize the reservoirs on the "Batra Oil field” in the Nile Delta of Egypt. The horizons and faults were mapped using two and three-dimensional seismic data. Time-depth structure maps and petrophysical parameters were produced. The reservoirs were also described using seismic characteristics. Three reservoirs containing hydrocarbons were identified. In five wells with hydrocarbon-bearing zones, structural maps of the horizons were created, and they showed that the major mechanism for trapping was fault-assisted anticlinal closures with top and bottom positions varying in thicknesses. The indicated promising zones are porous, permeable, and saturated with hydrocarbons. The average thickness of Abu Madi Level II reservoir is about 378 ft. net-pay of 62 ft., with average of porosity of 17.6 %, water saturation of 62.5 %, shale volume of 38 %, and hydrocarbon saturation of 37.5 %. The average thickness of Abu Madi Level III reservoir is about 291.5 ft. net-pay of 156 ft., with average of porosity of 20 %, water saturation of 61.3 %, shale volume of 14.9 %, and hydrocarbon saturation of 38.7 %. The deposition habitats were determined based on the morphologies of the logs, which show a transitional-to-deltaic deposition environment. New prospects have been suggested for drilling and additional research in this study. To more accurately characterize the reservoirs and understand the depositional settings, geochemical and biostratigraphic investigations should be conducted. |
