Abstract

Universal, operational and qualitative performance assessment of a selected development system, which can take into account geological heterogeneity, is one of unsolved problems in reservoir development planning.

A geological structure nature and sedimentation conditions exert influence on achievable sweep efficiency. On the one hand, existing static methods evaluate oil recovery without a digital analog of the system spatial heterogeneity. On the other hand simulation allows finding the desired parameter through long-term numerous calculations. Thus, the task of finding the sweep efficiency using a modern technique for describing spatial heterogeneity and for finding multivariable dependencies is set.

Key words:

topological characteristics, sweep efficiency, machine learning
