Abstract Production losses attributable to idle well stock were estimated based on the analysis of 2014-2015 oil production data of Russian vertically integrated oil companies (VIOC). It was shown that one of the main reasons for deactivation of wells is production casing leaks during well operation. The oil production losses of Russian VIOC caused by production casing leaks were estimated. A method is proposed to eliminate production casing leak intervals by expandable systems that employ a hydromechanical expansion method. The results of field application in wells of Povkhneftegaz of LUKOIL-Western Siberia and advantages of application of expandable systems for water shutoff are shown.
