The applied methodology consists of a number of steps including: data editing and normalization of the log data, modeling of the deep resistivity, electrofacies determination, standard log analysis, computing a production prediction index and summations. The 15 electrofacies determined were associated with the geological facies encountered within the field using cutting and core data. Consequently, porosity/permeability relationships were established between the core data and the productive electrofacies. These relationships permit to compute permeability from the computed effective porosity. A production prediction index was derived from the computed results which correlate well with existing production data. Zones of possible by-passed production were identified and some tested successfully. Finally, summations were used as input for original oil in place estimation, geological modeling and numerical simulation.
