Well Key® (HEX)

High Expansion


The Well Key brings a high degree of flexibility and reliability to the well completion design as it is designed to shift multiple sliding sleeves in a single run.

Running into the hole in a slick configuration, it is opened at depth and automatically engages with the hardware for which it was set-up for. Once engaged, the Well Stroker® provides the force to shift the hardware in the required direction and position.

The Well Key brings a high degree of efficiency to completions as it is designed to shift multiple sliding sleeves and open / close valves in a single run.

With active hydraulic control from surface, the Well Key ensures full integrity of downhole jewelry and reduced risk as it only opens when the tool reaches target depth.
