| Abstract | ||
| The present work evaluates the hydrocarbon potentiality of Abu Roash Formation in SWQ-25 well, Southwest Qarun (SWQ) Field, Gindi Basin, Egypt. The estimation of total organic carbon content (TOC) has been deduced using the overlay between deep resistivity and porosity logs. The results show that Abu Roash A Member is fair to good source rock (TOC ranges from 0.50 to 1.28 wt. %). While, Abu Roash D Member contains fair to very good TOC values (from 0.77 to 2.92 wt. %). In contrast, Abu Roash B and E members display poor to good source rocks, with TOC varies between 0.36 to 1.74 wt. % and 0.32 to 1.42 wt. %, respectively. However, Abu Roash C Member (with TOC varies between 1.50 and 2.19 wt. %) and Abu Roash F Member (with TOC differs from 1.54 to 3.16 wt. %) indicate a good to very good source rock intervals. The neutron porosity–resistivity overlay matches the density-resistivity overlay in carbonate members (A, B, C, D and F members) but a lack of resemblance in clastic units (E and G members). | ||
