Annotation:
An urgent task in oil field development is extending the period of their profitable operation. Key strategies for achieving this include optimizing the reservoir pressure maintenance system, reducing the share of inefficient injection, and bringing untapped reserves into production. Block-factor analysis is a widely used tool for addressing these challenges. The purpose of this work was to improve the methodology of block analysis, specifically regarding the principles of block allocation, approaches to analyzing the causes of well performance parameter deviations, and generating recommendations for enhancing the efficiency of the pressure maintenance system. As a result of the study, a comprehensive tool was developed. It enables analysis of the current state of the pressure maintenance system and facilitates prompt decision-making regarding changes to well operating modes. The step-by-step principle embedded in the methodology ensures clear and logical stages of analysis, while process automation significantly simplifies data gathering and preparation, reducing labor intensity and minimizing the risk of potential errors associated with manual data processing.
