| Abstract | ||||
| Using seismic AVO attributes and Inversion methods in predicting reservoir properties and geometry is an effective technique, especially in the Nile delta where the reservoir is heterogeneous. The main challenge in the current study is that most of the wells drilled in the area are either depleted or water folded. So the identification of gas-bearing sand using only seismic methods will be questionable. One of the advantages of the brownfield is that a lot of pertophysical data and production data are available. Petrophysical data and production history help to understand the reservoir properties like porosity, density, shale content, fluid content, and water level (gas water contact GWC). This study focused on using petrophysical and production data with the seismic inversion result to define the gas sand distribution and reservoir properties. To achieve the target of the study Structural interpretation, amplitude, p-impedance, and VP/VS maps were created to improve imaging of Abu Madi reservoir levels. The production history of the closed & current production wells has been revised and integrated with the seismic results. Based on these new information areas of possible residual gas were delineated. | ||||
