Workover rig

Workover & Intervention

A workover rig is a mobile rig specifically designed to perform remedial operations on producing wells. Unlike drilling rigs, they generally lack the heavy mud pumping and rotation capabilities required for drilling deep holes, but they are optimized for pulling and running tubing, rods, and pumps.

Workover rigs are deployed when a well's productivity declines or equipment fails. Common operations include replacing downhole pumps (ESP/Rod pumps), repairing casing leaks, or pulling the production tubing to access the reservoir for stimulation or cleanout.
