Abstract
South Abu El Gharadig Field (SAG) which is located in WD-30 Development lease and Alam El Shawish East (AES-E) field which is located in AES-3&4 development leases, they are basically forming one extended field across the block boundaries of WD-30 development lease (owned by EGPC and Apache and operated by Khalda petroleum company) and AES-E3&4 development leases (owned by EGPC and Naftogaz and operated by Petrosennan petroleum company),respectively. The perimeter of the study field at about 11 Km north east AG Field is located which is the oldest oil and gas field in Western Desert.
The SAG/AES-E structure is producing from the horst block and the southwest down thrown side which is called AG-88, both compartments are extended across the leases boundary.
Structural mapping of the Cretaceous rocks using the converted 2D seismic lines to 3D seismic cube and by means of the interpreting 13 main horizons from the deepest mappable horizon (estimated Top Early Jurassic) to the shallowest horizon (Oligocene time, Top Dabaa) and creating isopach maps and 2D restoration showed the evolution of this part of AG basin by extension of NW-SE tectonic event that started in Early Jurassic time and it was responsible for creating the Mesozoic AG basin going through the extension rotation towards NE-SW trend in Early cretaceous time that continued during the deposition of Kharita Formation up to Khoman-B Member, then after the deposition of Santonian Khoman-B Member, the first pulse of the compression tectonics had started, that affected the north east African plate and appears in the northern Western Desert to north Sinai in the series of NE-SW folds and extended towards Levantine basin and it’s called “the Syrian Arc Folds”. These pulses continued to Early Tertiary and resulted in inverted the deep-seated rift faults and evolve the two-way-dip structure of SAG/AES-E Field.
