Statistical Justification of Seismic Facies Analysis of Complex Carbonate Reservoir

Seismic facies analysis is one of the methodological approaches to the study of the geological structure of the field, and at present it is a standard part of the interpretation process. Seismic facies analysis plays an important role in the process of seismic and geological monitoring, which is carried out at the stage of field development. A comprehensive interpretation of seismic and well data allows predicting at a qualitative level lithofacial variability in local areas, which contributes to a more rational placement of production wells. The prompt receipt of geological information allows to refine the facies model with each new well, refine the reservoir distribution contours, find new relationships between the structure of the geological environment and seismic image variations, and make more accurate subsequent predictions. The main purpose of applying various algorithms to extract facies is to reduce the ambiguity of the geological interpretation of geophysical fields.
