HLWM

Hydraulic-line downhole wet-mate connector

Rated up to 6,000 psi [41 MPa]
Rated to 250 degF [121 degC]

Efficient connect-disconnect system for multitrip completions, including intelligent completions

The HLWM hydraulic-line downhole wet-mate connector enables deployment of a multitrip completion that uses hydraulic equipment (such as flow control valves, isolation valves, or chemical injection mandrels) in the lower completion.

This allows a cost-effective workover of the upper completion without having to retrieve the lower completion, making it ideal for use in intelligent completion designs.

Faster, safer workover operations

A large number of HLWM installations have been successfully competed in the Middle East and North Sea, in offshore deviated wells that are equipped with hydraulic valves in the lower completion and an ESP in the upper completion. In many of these installations, the upper completion has been retrieved and the ESP replaced with a 100% success rate without retrieving the lower completion, saving significant rig time and cost.

Simplified connections, even in deviated and horizontal wells

The connector comprises two subassemblies, the receptacle and the stinger, which are run with the lower and upper completion, respectively. The concentric design eliminates the need for any orientation downhole when stinging into the lower completion. This key feature makes the system reliable and easy to use in highly deviated to horizontal wells.
