It is intended for the well operation with the electric submersible pumping equipment with the production casing leak intervals above the productive formations, as well as in the dual production and injection ones.

This packer is designed for well operation with submersible electrical pumping equipment with leak intervals of the production string above producing formations.

It is designed to bypass fluid or gas from the annulus to tubing when they are operated with the closed annulus.

It is designed for operation of the wells with high gas ratio well fluid with submersible pump equipment. It allows to operate with the closed tubing using APG gaslift effect for production strings with nominal outside diameter of 140 (5 1/2")-178 mm (7").

It is designed for disconnection of the tubing string in case of complications with tripping the downhole equipment in and out.

It is designed for a long-term sealed separation of the casing string intervals and protection of the casing against the dynamic effect of various well operations.

It is applied in oil production using ESP unit with water-repellent treatment of the bottom-hole area of the well and avoidance of well-killing fluid entering the bottom-hole formation zone in production strings with nominal outside diameter of pipes ranging from 140 (5 1/2")-219 mm (8 5/8”).

It is designed for communication and pressure-tight separation of the tubing interior and annulus.

It is used for a two-way fluid bypass through its cavity and as a check valve in the tubing string.

It is designed for the tubing string connection and disconnection with the stand-alone packer and anchor equipment in the production string.

It is designed to set and disconnect a tubing string, to provide a movable pressure-tight connection between the tubing string and packer and anchor equipment in the production string as well as to retrieve this equipment.

It is designed for installation, disconnection and connection of the tubing string with the stand-alone packer and anchor equipment in the production string.

It is used during oil extraction with simultaneous insulation of upstream leakage interval or of perforation with water production in the production casing with nominal outsidenal diameter of pipes 140 (5 1/2")-178 mm (7").

It is used for oil extraction with pumps and with simultaneous insulation of upstream leakage interval with water production in the production casing with nominal outside diameter of pipes 140 (5 1/2")-178 mm (7").

These packers are designed for sealed separation of casing string intervals and protection of the casing against the dynamic effect of various well operations..
