Determination of Inflow Profile Based on Input Information Considering the Hydrodynamics of Two-Phase Systems

Abstract

To solve multi-well development problems, it is necessary to form an understanding of the inflow profile in the perforation zone. Research shows that the problem of determining the inflow profile for planning and conducting oil production is highly relevant, especially given the widespread development of fields worldwide. Increasingly, inflow profile identification is being carried out without directly stopping well operation, relying on indirect measurements and publications. However, accurate assessment requires precise measurements. The relevance of determining the inflow profile is due to the necessity of optimizing the production system. Reducing downtime and accurately identifying production intervals are key aspects of well performance efficiency. This paper proposes a method to determine the inflow profile based on available input information. The proposed method enables researchers to identify significant inflow zones without requiring flow shut-off or fluid level measurements. The proposed approach represents a valuable tool in designing multi-well field development and planning the layout of new wells.
