usage example

Deployment of a Cemented Liner in a Production Well

location

Chepakovskoe Field, Stavropol Krai, Russia

problem

LLC "NDP Chepakovskoe" required the deployment, installation, and cementing of a liner in a deviated production well in the Chepakovskoe field, with a formation temperature of 146 °C, as part of its field development program

solution

Our company supplied the Osprey cemented liner hanger system, equipped with hydrogenated nitrile (HNBR) sealing and packing elements rated for temperatures up to 149 °C

work process

The Osprey liner hanger was run into the well on a drill pipe string and set inside the production casing

The anchor section of the Osprey liner hanger was hydraulically set using surface pumping equipment. Following verification of anchoring, the liner was cemented while being rotated continuously

The running tool was then released hydraulically. The packer section of the Osprey hanger was mechanically set using applied axial load. This created a secure pressure barrier rated for 69 MPa and 149 °C

The packer element, designed for high-temperature applications, provided a reliable seal even under challenging downhole conditions.
