Well Key®

Dimple tool

Introduction

The Well Key® Dimple Tool is designed to permanently lock open surface controlled subsurface safety valves 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.

Overview

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 pinpoint accuracy, the Well Key provides the flexibility to open any type of downhole completion valve. And its active hydraulic control and high expansion ratio ensures full integrity of downhole jewelry and reduced risk since the Well Key is only opened when the tool reaches target depth.
