Dimple Tool
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.
Featured case
A critical well barrier issue in the North Sea prompted the rapid development and deployment of a hybrid 'ShiftLoK' solution to restore well access by shifting, dimpling, and locking open an inoperable DHSV in a single run.
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.
