PRO-YAMOG3(F)-KU Axial Mechanical Set Packers with Integrated Hydraulic Anchor and Equalizing Valve (rated operating pressure up to 70 MPa)

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.


  • Recommended for multiple massive hydraulic fracturing in one round-trip;
  • for pressure testing and leak finding in the casing string;
  • for pressure acidizing.


  • packers contain expandable supports to prevent rubber seal elements extrusion into annulus which increases the reliability of sealing and relieves packers unsetting;
  • enlarged passage of 53 mm for casing strings with nominal diameter of 140 to146 mm;
  • reliable sealing of production string during operations requiring high pressure differential on the packer;
  • easy to release without additional tensile loads;
  • pressure testing seat in the top part of packer allows to carry out pressure testing of the tubing prior to well operations;
  • an integrated mechanical equalizing valve reduces accident rate and allows:
  • in case of hindered release of packer, to equalize pressure above packer and inside the tubing by tensioning the tool upwards in excess of the preset valve actuation force;
  • in case packer gets stuck with the valve in the open position, to flush or kill the well.


  • packer is equipped with an integrated hydraulic anchor to keep the packer from moving upwards which is actuated by generating pressure inside the tubing after setting of the packer;
  • packer is set into the well mechanically by axial movements of the string (no tubing rotation required) and brought into run-in position by tensioning of the string;
  • packer can be used multiply for one round-trip operation;
  • packer’s equipped with an integrated equalizing valve used to equalize the annulus pressure above the packer and pressure inside the tubing string;
  • equalizing valve is mechanically actuated by tensioning the tool upwards;
  • actuation force for the equalizing valve is preset by the manufacturer upon the customer’s request;
  • valve is closed by unloading the tool.
