PETROPHYSICAL EVALUATION AND RESERVOIR HETEROGENEITIES AND THEIR IMPACT ON THE WATER MOVEMENTS. CASE STUDY: ABU MADI - EL QAR'A GAS FIELD, NILE DELTA, EGYPT

Abstract

Abu Madi Formation of Abu Madi-El Qar’a gas field constitutes the main gas producing horizons in the onshore north Delta Basin, since 1975. The facies complexity of the reservoirs is the main controlling factor for the irregular and differential water movements. The results of interpretation of the available subsurface geological, geophysical and borehole data have been integrated in the form of petrographical, mineralogical, sedimentological and petrophysical studies to delineate the lithofacies, lithostratigraphy, depositional environments, structure and geometry of Abu Madi reservoirs in the study field.
