Annotation:

When conducting wells’ current repair and workover in a number of fields of JSC "Orenburgneft", the most frequently occurred complication is the process fluid absorption, associated, firstly, with the operation of wells under conditions of abnormally low reservoir pressure and, secondly, the operation of several layers with different reservoir properties by wells. The article presents the results of pilot tests of the technology for reducing catastrophic losses of process fluid in the fields of JSC "Orenburgneft".
