POS-GRIP®

POS-GRIP Technology was initially created as a method of supporting oil field tubulars with an externally activated radial friction grip.

Its first application in the oil and gas industry was through the introduction of an adjustable rental wellhead system for jack-up exploration drilling.

The benefits demonstrated by the POS-GRIP jack-up drilling system, used in conventional field applications, led to the development of proprietary, specialised high pressure and high temperature (HP/HT) HG Production Wellhead systems, which are key to the industry as it shifts to more extreme operational environments in response to increasing global demand for oil and gas products.

The operational and cost saving benefits delivered  by the original POS-GRIP standard pressure exploration jack-up drilling system led to the development of proprietary, specialised high pressure and high temperature (HP/HT) jack-up drilling systems as well as HG Production Wellhead systems, and Connectors

The system is energised by reusable hydraulic devices which are fitted temporarily to flanges on the outside of the wellhead. The simplified drawings above show how a POS-GRIP clamp arrangement can be configured to squeeze the outer pipe so that it grips the smaller pipe inside.
