Annulus Gas Vent Valve is used with ESP packer P-EG-AD or other ESP packers. It is intended for venting gas from annulus under packer to above packer annulus or conversely in case injecting gas to under packer annulus.

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 5 1/2" - 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..

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

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

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 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 used for pumping production of oil with simultaneous isolation of a leak interval located above with water inflow in production strings casing OD from 5 1/2’’ to 7’’ in.

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

Designed for hermetically separating casing intervals during the operation of oil, gas condensate and gas wells, tachnological operatios

Completion and production from oil wells by means of ESP or other submersible electrical equipment located below individual sections of the production string require sealing.

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 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.
