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

Well Key® Dimple Tool is designed to permanently lock open surface controlled subsurface safety valves in a single run. With pinpoint accuracy, the Well Key® Dimple Tool deforms the sleeve by making “dimples” in its surface, thus locking the sleeve in a fixed open position.

Its active hydraulic control and high expansion ratio ensures full integrity of downhole jewelry and reduced risk since the Well Key® Dimple Tool is only opened when the tool reaches target depth.
