Abstract

Abadan plain is considered as the one of the hydrocarbon sub basins in south of Zagros in Iran which from the tectonic viewpoint is known as the Arabian plate north platform terminal. Existence of basic differences in Abadan plain sediments due to the structural geological viewpoint with Zagros sediments area and Dezful embayment shows the petro physical studies necessary. So for determination of porosity, shale volume and water formation saturation from important rank factors after the determination by the probes and data sending and their processing as the full set logs, related data was prepared as the diagrams and then determination and evaluation was performed by two certain and probable methods. As it is observed in Sarvak Formation interval, the results showed that major lithology was carbonate and also observed with Dolomite rocks in the depth of 3250-3575 and 3450-3475 m. From the oil reservoir viewpoint, 3125-3265 m is the best hydrocarbon depth in wells, though beside oil zone, free water zone is present but due to the 30% water saturate sub limit can almost have more oil reservoir. But due to the very low quality, next predicts for depth less than 3125 and 3240 m till the Sarvak interval ending has no certainty.
