Reservoir Property Solutions Using Porosity and Poisson Cube Prediction from 3D Seismic and Well Log Data – Case Studies from Russia, Western Siberia

G-21 RESERVOIR PROPERTY SOLUTIONS USING POROSITY AND POISSON CUBE PREDICTION FROM 3D SEISMIC AND WELL LOG DATA. CASE STUDIES FROM RUSSIA WESTERN SIBERIA SUMMARY New data on reservoir shape and oil deposit structure of the Kogalym oilfield in Western Siberia was obtained from predicted porosity and Poisson’s ratio cube. Thin-layered sandy reservoirs was described using AVO-analysis of seismic 3D data inversion and well log data. More accurate information on the position of top of productive sandstones in Cretaceous formation including construction of horizontallylayered depth-velocity model of a media and depth pre-stack migration of gathers. The integrated analysis of Poisson’s ratio
