Main Article Content
Abstract
Under conditions of increasing depth and complexity of well overhaul, especially during the opening of the second wellbore under conditions of abnormally low reservoir pressure (APDC), the risk of complications arising - absorption, seizure, and contamination of the productive reservoir - increases. The work examines the causes of these complications and proposes approaches to preventing them by using lighter washing fluids with multifunctional additives. Analysis of operational indicators and technical and economic effects was carried out. It has been shown that modified systems can reduce accidents, increase the efficiency of major repairs, and preserve the reservoir's reservoir properties.
