Conventional wisdom says that subsea wells need a semi-submersible rig for drilling, workover and abandonment operations. But, a semi-submersible rig isn''t well suited to the rough environmental conditions and relatively shallow water depths (less than 120 m) found in regions like the North Sea. For these cases, Aquaterra Energy''s high

Brake bands play a pivotal role in the braking system of workover rigs. Positioned around the rig''s brake drum, these bands tighten to create friction, ultimately slowing down or stopping the rotation of the drum and controlling the descent of the load line. 2. **Materials and Construction:**. Brake bands are commonly manufactured from
In many cases, workover implies the removal and replacement of the production tubing string after the well has been killed and a workover rig has been placed on location. Through-tubing workover operations, using coiled tubing, snubbing or slickline equipment, are routinely conducted to complete treatments or well service activities that avoid a full
