Abstract

Summary

The results of 2D full-stack seismic inversion technology for predicting reservoir properties applied to the area under the study area within Triassic succession of the south-east Pre-Caspian sedimentary basin. Hydrocarbons, mostly oil trapped by salt dome wall and faults. Full-stack seismic lines, wireline logging data and seismic velocity were integrated to generate P-impedance volume. The porosity was estimated from the relationship between the absolute P-Impedance result and the porosity effective at the well locations. Generally, low P-Impedance or high porosity packages over the area indicate higher probability of hydrocarbon sands in the Reservoir interval. The localized high P-Impedance at the Reservoir interval at the northern part of area could reveal the distribution of the micro-conglomerate reservoir, however more geological-geophysical should be integrated to interpret anomalous geobodies. Data obtained allows concluding that it is not possible to discriminate the distribution of the hydrocarbon sands due to strong overlap of the acoustic impedance of the hydrocarbon bearing sands and the background lithology.
