Dimple tool

Introduction

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.

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.
