Hydraulic Workover Unit

A Hydraulic Workover Unit (HWU) is a self-contained well intervention system designed to perform workover, completion, snubbing, and well maintenance operations on live or dead wells without the need for a conventional drilling rig. Powered by hydraulic cylinders instead of a traditional derrick and drawworks, the unit provides precise control for running and pulling tubing, drill pipe, and downhole tools while maintaining well control under pressure.

Our Hydraulic Workover Units are available for sale and lease, delivering safe, efficient, and cost-effective well intervention solutions for onshore and offshore oil and gas operations.
