| Abstract | ||
| Alam El-Bueib Formation (AEB) is a productive rock unit in the Egyptian Western Desert .It ranges in age from Middle Jurassic (Callovian) to Early Cretacecus (Barremian). It is mainly composed of sandstone with siltstone, shale and carbonate streaks. Lignite and carbonaceous shales are occasionally common, particularly near the base. It covers most of the areas of the northern Western Desert. It uncomfortably overlies the Masajid Formation. Objectives of this study are to describe the reservoir petrophysical characteristics of the sand seen in Umbarka and South Umbarka fields, to study the petrography, to study the effect of lithology on the distribution of petrophysical parameters, and to evaluate the hydrocarbon potentialities of the AEB-D1 Sand reservoir. Well log data belonging to seven drilled wells were interpreted and integrated with the other subsurface information to evaluate the petrophysical characteristics of the AEB Sand Reservoir. The log data were corrected prior being used for determination of the average petrophysical parameters of the AEB-D1 Formation. These parameters were plotted in the form of maps representing the areal distribution of three petrophysical parameters (shale volume, total and effective porosities, and water and hydrocarbon saturations. In this study, the potential un-tested bypassed zones were identified and mapped. According to the petrophysical distribution of the maps of AEB-D1, the Original Oil Inplace (OOIP) is estimated to be about 19.5 Million Stock Tank Barrels (MMSTB). The maps also highlight a prospective area in the South Umbarka area (Khepri-Sethos). | ||
