High-Force Linear Actuator Tool - ReSOLVE Service | Schlumberger

High-Force Linear Actuator Tool

Controlled, measured application of axial force

Minimized-imprint anchoring for maximized traction

ReSOLVE instrumented wireline intervention service combines an anchor and linear actuator modules to reliably apply controlled axial force to well components. The linear actuator tool can be used with either the ReSOLVE service universal shifting tool or third-party shifting, pulling, or other interface tools.

The anchor module opens with the industry’s largest reach from the tool OD to the tubing of nearly 2 in [5 cm] diametrically. Up to 150,000 lbf [667,230 N] of anchoring force is precisely applied for maximum traction while the innovative low-stress anchor grips minimize the impact on the tubing.  

Multiple extension and retraction

Once anchoring is confirmed to the surface, the linear actuator can be extended or retracted multiple times to apply a large, controlled force of up to 40,000 lbf to the specific well component. Continuous measurements of displacement and the applied force validate completion of the operation.

The patented, innovative low-stress anchor grips (left) used by the ReSOLVE service are designed with rounded, shallow, and wide grooves that minimize the imprint effects on tubing (top) while also providing very high traction capability. The effects on tubing were evaluated through finite-element analysis of stress (bottom) to optimize the grip design.
