Integration Petrophysical and 3D Seismic Data Analysis to Evaluate Miocene Remaining Potentiality, Temsah Field, Offshore Nile Delta Egypt

Temsah is a giant gas field located in the northern part of the Nile Delta, North East of Damietta and North West of Port Said and is about 40 km off the coast line, the extension of the field area is about 60 sq. Km, the reservoir is hosted in terrigeneous sandy rocks of middle-late Miocene (Serravallian-Tortonian) ascribed to Sidi Salem Fm. Located at depth ranging between 3500 and nearly 4000 m ssl



The present study represents the integration between the well – log data and seismic data. The well – log data includes resistivity (deep and shallow), porosity (sonic, density and neutron) and gamma-ray of six scattered wells (TNW-3, T-5, T-3, T-7, T-11, and T-2), using computer program (ELANPLUS) to evaluate quantitatively the different petrophysical characteristics Heff, Vsh, Ø eff and Shr.



All petrophysical characteristics which resulted from the previous steps will be represented vertically in the form of petrophysical data logs (PDL) and laterally by iso-parametric distribution maps (effective thickness, shale content, effective porosity and hydrocarbon saturation). Also the attributes maps will be performed to show the sand distribution and lateral change in facies.



Petrophysical data logs (PDL) are vertical representations of all the petrophysical features that were deduced from the preceding processes. Effective thickness, shale content, effective porosity, and hydrocarbon saturation are examples of iso-parametric maps that show the lateral fluctuations in the petrophysical parameters.
