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.
Featured case
An operator in West Africa expanded the objectives of their first well in a new field from producing first gas to producing first gas and first oil. This change in goals...
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.
This High Expansion version provides the operator the ability to pass through small restrictions and still actuate hardware in large liners. 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.
