Oil production equipment for simultaneous seal of leakage interval

Technology and set of equipment for simultaneous seal of leakage intervals are used for oil production from old wells with flow rate up to 75 m3/day and defected casing (leaking) without making expensive workover. The main advantage of equipment application is saving time and money for workover of wells with defected casing. Equipment set can be mounted during well servicing with application of conventional tools.
