Abstract
One of the main problems for oil & gas industry in the Udmurt Republic is a high content of water producing along with oil, caused by involving many fields of the region into the final stage of development. Effective performance of repair & insulation works, also known as remedial well servicing, allows slowing down the tendency of increasing the excess water coproduction from producing wells. However, when designing repair & insulation work technology, the correct determination of the water cut source based on the research results plays a key role. This article considers the chief causes for the early water cut increase in wells and forms their classification. Taking oil fields located in the Udmurt Republic as examples, the main ways of water inflow to the bottom of production wells are examined. Comprehensive analysis shows the efficiency of repair & insulation works at the fields in question.
