The Procedures of the Study of Geometry of the Reservoirs and Fluid Traps Based on Analyzing of Seismic and Well-Log Data in the Prediction of Oil-and-Gas Objects

This paper represents the typical examples of application of the united procedures of seismic and<br>well-log data interpretation to study the reservoirs and fluid traps on the oil and gas fields of<br>West Siberia. The procedures are based on the inversion methods of seismic data processing<br>with the instruments of the interpretation system ReapackRD (LINUX/Intel) and methods of<br>crosswell correlation of the strata and their identification with lithofacies and acoustic features,<br>obtained from seismic and log analyses. The procedures allow to trace the boundaries of the<br>reservoirs, to study the reservoir morphology, the reflection coefficients fixed in the strata’s top<br>and bottom boundaries, the fault zones and the zones of the lithologic replacement of permeable<br>rocks by leakless ones, which determine the hydrodynamic environment of productive strata.
