The process of pinpointing unconventional shale gas sweet spots demands an extensive analysis of various geological, geochemical, petrophysical, and geomechanical factors. The Amoun field, which is a vital oil and gas reserve in the northern Western Desert of Egypt's Shushan Basin, was examined in this research, specifically targeting the Upper Safa shale as a potential shale gas reservoir. The geological investigation revealed that the Middle Jurassic Upper Safa member was found at a depth range of 12,036 to 12,065 ft. The gross thickness is approximately 602-790 ft., with an average of 696 ft. The potential shale gas sweet spot of the entire Upper Safa member has a net thickness range of 132-313 ft., with an average of 222 ft. Additionally, the sweet spot intervals are characterized by average TOC values range of 1.6-3 wt.% and type III kerogen, with a little contribution to typ.. View More»
