摘要: The estimation of rock petrophysical parameters is an essential matter to characterize any reservoir. This research deals with the evaluation of effective porosity (Pe), shale volume (Vsh) and water saturation (Sw) reservoirs at Kumait Dujalia fields, which were analyzed from well log seismic data. absolute acoustic impedance (AI) relative (RAI) derived a model based on inversion 3-D post-stack NahrUmr formation’s sand are identified by RAI section study area. Nahr Umr sand-2 unit in field main reservoir; its delineation depends available logs AI sections information. results logging interpretation showed decrease Sw Vsh increase oil reservoir area, coincides values. existence Du-2 revealed convergence those wells , along some differential values that may be related changes lithology fluid density.
