| Summary: | Bahariya Formation in Western Desert Egypt is one of the major complex oil bearing reservoirs in<br>Egypt. Many discoveries have revealed the high oil potentialities of this formation.<br>Detailed sedimentological interpretation was performed over the imaged highly complicated and<br>inconsistent reservoir interval for Abu Roash “G” Member and Bahariya Formation in two drilled wells,<br>North Western Desert of Egypt.<br>Twenty lithofacies types were defined from the images of the two investigated wells. Individual<br>lithofacies were defined based on detailed description of sedimentary structures from the image logs.<br>The sand lithofacies of the Bahariya Formation and dolomite of Abu Roash “G” member were assigned<br>pay values. The identified electrofacies are calibrated with the cored intervals in one of the two wells.<br>The Bahariya Formation in the studied two wells is interpreted as a tidal flat deposits and characterized<br>by the following subenvironment: barrier bars, tidal channel and tidal flat muds. The Abu Roash “G”<br>member is considered as a subtidal carbonates and characterized by the presence of frequent<br>secondary dolomite.<br>Correlation based mainly on the data gained from FMI sedimentological facies analysis and<br>interpretation has been carried out to through light on the lateral facies changes and consequently to<br>solve many problems related to the reservoir complexity. The missing of some facies associations<br>confirms the presence of faulting. |
