Abstract
The Bejil field case study shows the comparison of 3D lithology volumes built by various methods, applied world-wide. A net-reservoir volume is an important and integral part of 3D geological models, which determines the oilnet pay part of the reservoir. The quality of the geological model directly affects the concept of the studied geological environment. Two lithology volume options are considered in detail. The first method, which is more popular in domestic applications, involves building a lithology volume directly based on logging data interpretations. The second method, which is more widespread internationally, involves building a volume of facies environments followed by distributing various lithotypes in a reservoir taking into account the facies structural features. As a result, we made allowance for the tasks and geological features of the field and chose the best modeling method.
