Petroleum System Of Gindi Basin And Mubarak Sub-Basin, Qarun Concession, Western Desert, Egypt, Mostafa Hussien, Tharwt Abdel Hafeez, Mohammad Fathy, Mohammad El Ghamry Dec 2021

Petroleum System Of Gindi Basin And Mubarak Sub-Basin, Qarun Concession, Western Desert, Egypt, Mostafa Hussien, Tharwt Abdel Hafeez, Mohammad Fathy, Mohammad El Ghamry

Al-Azhar Bulletin of Science

The study area is located to the west-southwest of Cairo, which includes Qarun and East Bahariya Concessions. Two main prolific sedimentary basins included; Gindi and Mubarak basins. Geophysical and 3D seismic data integrated with well logs, as well as geochemical data from 5 wells, all resulted in an accurate delineation of the structure traps and a reassessment of the elements of the petroleum system in this area. Mentioned basins are formed as a result of Late Cretaceous wrench tectonics. Such tectonic regime was responsible for generating oil entrapment and conduit faults in Cretaceous reservoirs. Detailed geochemical analysis proved that the …


Lineaments Detection And Groundwater Exploration Using Gis And Geo-Electric Data At Wadi El-Asyuti Area, Eastern Desert, Egypt., Ashraf Abdo, Hassan Sabet, Mohamed Mebed Dec 2021

Lineaments Detection And Groundwater Exploration Using Gis And Geo-Electric Data At Wadi El-Asyuti Area, Eastern Desert, Egypt., Ashraf Abdo, Hassan Sabet, Mohamed Mebed

Al-Azhar Bulletin of Science

Geo-electric and GIS data toWadi El-Asyutiarea, central Eastern Desert, Egypt have been used for identify the different lineaments and possibilities of the occurrence of the groundwater.Shaded relief maps were developed from the digital elevation model (DEM) which used for identifying the lineaments. Geomatica software extracted the lineaments at the final maps with NW-SE direction.Meanwhile the geologic fault trends derived from geologic map take NW-SE, WNW-ESE, N-S and ENE-WSW directions. Twenty two electric resistivity soundings were conducted in the study area and three cross sections. Drilled well is near from VES-22. Geo-electric and drilling results reflected three layers. The first one …


Reservoir Characterization Of The Upper Abu Roash “G” Sandstone In West Of Nile Area, Western Desert, Egypt., Esam Abd El-Gawad, Mohamed Fathy, Mahmoud Elsherbiny Dec 2021

Reservoir Characterization Of The Upper Abu Roash “G” Sandstone In West Of Nile Area, Western Desert, Egypt., Esam Abd El-Gawad, Mohamed Fathy, Mahmoud Elsherbiny

Al-Azhar Bulletin of Science

Accurate reservoir characterization is an important stage in developing, managing the reservoir, and enhancement the production which depends mainly on a good description and precise interpretation of the reservoir facies. The study area is considered as a part of Qarun Petroleum Company’s development leases which are located in the western side of Beni Suef Basin, the northeastern Western Desert which is considered the most important petroleum province in Egypt. Integrated sedimentological analysis of core description, petrographic and mineralogical constituents were carried out on the Upper Abu Roash “G” sandstone reservoir. The core description included 81.25 feet from the WON C-18 …


Reservoir Characterization And Petroleum Geology At Esh El Mallaha Field, Southern Gulf Of Suez, Egypt, Ahmed Embabi, Mohammad Abdelwahhab, Nabil Abdelhafez Dec 2021

Reservoir Characterization And Petroleum Geology At Esh El Mallaha Field, Southern Gulf Of Suez, Egypt, Ahmed Embabi, Mohammad Abdelwahhab, Nabil Abdelhafez

Al-Azhar Bulletin of Science

Reservoir quality assessment, pointing to possible capacities for holding hydrocarbons, is crucial during exploration-phases of petroleum. This investigation closely examines the petrophysical properties of Nubia-Sandstone Formation upon performing well-log analysis of the available well-log data located at West Esh El Mallaha area, southern part of the Gulf of Suez, Egypt. It is an attempt to reveal the hydrocarbon potentialities within Paleozoic reservoirs of the area. Nubia Formation represents an important reservoir in the Gulf of Suez province with at least 15% of hydrocarbon production potential. Well-log analysis, in means of defining the petrophysical properties (shale-volume, porosity, and water-saturation), of Nubia …


New Fluorite Index Using Aster Data Of Gabal Abu Diyab Area, Central Eastern Desert, Egypt, Mahmoud Hafez, Ibrahim Abu El-Leil, Nehal Soliman, Mostafa Abu Bakr Dec 2021

New Fluorite Index Using Aster Data Of Gabal Abu Diyab Area, Central Eastern Desert, Egypt, Mahmoud Hafez, Ibrahim Abu El-Leil, Nehal Soliman, Mostafa Abu Bakr

Al-Azhar Bulletin of Science

Remote sensing represents a significant function in the exploration of minerals. Extraction and identification of mineral occurrences in semi-arid to arid regions are some of the remote sensing confirmed uses. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images have been combined with band ratio processing technique for detecting the fluorite mineral occurrences in the area around Gabal Abu Diyab, Central Eastern Desert, Egypt. The proposed band ratio derived from ASTER images Spectra [(b8/b6) * (b5/b3)] can be considered to represent the new Fluorite Index (FI). The USGS Spectral libraries are used to extract the new index and validated …
