Surface-controlled recovery of loose objects
Welltec® Wellgrab CLAW is a surface-controlled, motor-driven fishing tool designed for the safe and efficient retrieval of loose, irregular-shaped objects from the wellbore. From tangled wire to dislodged components, it offers a modern, data-driven approach to resolving even the most challenging fishing operations.
What sets the CLAW apart is its ability to measure the wellbore’s inner diameter—as well as the inner and outer diameter of the target—in real time. These parameters help confirm correct placement and a secure latch before retrieval begins, reducing uncertainty and risk.
With fully repeatable actions and surface-controlled precision, the Wellgrab CLAW is the industry’s leading solution for optimizing fishing operations and minimizing downtime.
Featured case
The Wellgrab™ CLAW showcased its adaptability in a challenging North Sea fishing operation, providing live measurement readings to confirm successful latching by corresponding to the outer diameter of lightweight, tightly curled cable. Deployed via the Well Tractor®, the CLAW confirmed engagement through force signatures and accelerometer data, with the operation completed in three planned runs. The intervention restored production after four months of downtime and eliminated the need for a costly workover.
