Abstract The Late Messinian Abu Madi Formation represents the most prospective deep reservoir target in the Nile Delta. Hydrocarbon exploration in Nile Delta over the last few periods attempts to study the Abu Madi reservoir quality and distribution. The integration of Rockphysics, AVA, Seismic Interpretation, Seismic Attributes, and Seismic Inversion could successfully determine the characteristics of Late Messinian Abu Madi Formation at North West Khilala (NWK) Field. It is located in the central onshore part of the Nile Delta, Egypt. NWK concession located in the eastern margin of Disouq concession close to producing West khilala field. A complete well data for four wells exposed a complex lateral and vertical reservoir stacking patterns with extremely heterogeneous reservoir parameters. Seismic data was inverted in order to describe the overall lateral extent of the field and gross reservoir character the reservoir sequence was attributed to lacustrine turbidities deposited in semiisolated Late Messinian Basins. The Abu Madi Formation can be divided in to upper and lower members, which are separated by Intraformational shale barriers is common. AVA analysis performed on the top of Abu Madi reservoir, suggested a class 2p. Pre-stack Inversion process integrated with rock physics modeling of the wells to create high resolution multiple rock property models with the aim of obtaining reservoir characterization and the observed pressure trends. One significant shale barrier subdivides the Abu Madi reservoirs in to Upper and Lower levels that display different pressure depletion trends. The pressure depletion of lower Abu Madi in North West Khilala field was investigated laterally and vertically by relative/ full spectrum inversion and MDT pressure data respectively. This depletion due to communication with West Khilala field, which was produced from lower Abu Madi Reservoir in 2007. |
