It is designed for pressure-tight separation of the casing string intervals.

It is designed for tripping in and setting of PRZ drillable plug.

It is 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 sealed separation and communication between the annulus with the interior of the tubing.

It is designed for sealed separation and communication between the annulus and the interior of tubing.

It is designed for sealed separation of the casing string intervals.

It is designed to equalize the pressure in the annulus above the packer and the pressure inside the tubing string.

These packers are designed:

• for sealed separation of casing string intervals and protection of the casing against the dynamic effect of various well operations;
• to equalize the annulus pressure above the packer and the pressure inside the tubing string;
• for pressure testing of the tubing above the packer.

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

This sub is designed to easily disconnect tubing from stuck downhole equipment during well operations. 

This BHA is used for hydraulic fracturing including massive hydraulic fracturing in production strings with tubing of nominal outside diameter of 140 mm (5 1/2") to 178 mm (7") with pressure differential up to 100 MPa (15000 psi)
