Summary:
The goal of this paper is to determine a new approach for high efficient reservoir characterization by predicting dynamic petrophysical properties. In this study, by analyzing core and well log data, the effective porosity log for a productive member of Zechstein formation in four wells was determined. This member is mainly carbonate and counted as one of the producing horizons in North Sea. The variation of effective porosity versus acoustic impedance, as the bridge between seismic surveying and petrophysical properties have studied, and a meaningful trend between two properties observed .By applying genetic inversion, this trend extended to volume of seismic data. The result of this procedure confirmed by seismic attribute analysis.
