INTERACTION OF RING BATTERY WELLS

Abstract

This study examines the development and operation of wells, as well as the phenomenon of well interference in productive reservoirs. The relevance of the topic is determined by the need to optimize the operation of oil and gas fields and minimize losses during drilling and production, taking into account the hydrodynamic connection between wells. The aim of the research is to analyze the inflow of liquids and gases to wells, assess interference effects, and evaluate the impact of various operational modes of well batteries. The objectives include studying well operation modes, determining interference coefficients, analyzing well placement in a ring battery configuration, and assessing the influence of well design and fluid properties on total well production. The study analyzed three well operation modes: constant bottom-hole pressure, constant flow rate, and variable parameters. It was found that the total production of a group of wells depends on their arrangement and number, and interference coefficients allow predicting the reduction in the efficiency of individual wells. Placement of wells in a ring battery configuration contributes to optimizing field performance and minimizing mutual influence between wells. The results confirm the importance of a comprehensive approach to well planning and operation, considering both hydrodynamic connections and physical-chemical properties of the fluid. Practical applications include selection of operational modes, forecasting the efficiency of water or gas injection activities, and optimizing the planned number of wells.
