Abstract The integrity of borehole walls is critical in drilling operations, particularly in formations prone to drilling fluid loss. This study addresses the causes of wellbore wall integrity failures and explores methods for eliminating the resulting complications. The electrochemical method for fastening wellbore walls is analyzed, focusing on its advantages, disadvantages, and potential applications. A technique has been developed to optimize the electrode arrangement in electrochemical fastening, determining the necessary number and size of cathodes and anodes. The goal is to minimize energy consumption while achieving the maximum allowable electrical resistance of the stabilized formation. The research establishes that increasing the number of anodes results in higher energy consumption, particularly when their number exceeds a critical threshold, reducing the distance between them and increasing energy usage. Additionally, the resistance of the electrode system decreases logarithmically with an increasing number of anodes. The study identifies an optimal anode number for each specific ratio of anode to cathode diameters, allowing the system to maximize the electrical resistance of the stabilized rock with minimal power consumption. The proposed method provides a framework for determining this optimal configuration.
