Single-line flow control valves
For high-reliability production control with fewer hydraulic lines.
Hydraulic-line downhole wet-mate connector
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.
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.
