New 120-ton power swivel for fishing, workovers
This new hydraulic, motor-driven, 120-ton power swivel with offshore package promises smooth, accurately controlled, shock-free rotary power that is suited for fishing and workover operations.
It handles internal or external cutting of tubing, casing, or drill pipe; drilling out plugs, packers, or cement; milling operations; or scraping casing-whenever shock-free, controlled torque is essential to eliminating the potential danger of twist-offs or damage to cutting tools, the firm points out.
In addition to oil and gas wells, it is also suited for light to medium drilling applications including water wells and pilings for piers and foundations. Suspending the swivel from a boom or crane eliminates a great deal of setup time or shifts to additional locations. The swivel is also can be used for coring operations. Any length of core may be taken. Accurate, smooth torque ensures against damage to core tools or strings, the firm says.
The skid-mounted unit is made of heavy-duty structural tubing with welded construction. To meet increased environmental safety regulations, it is equipped with a containment lip to eliminate fluid spills. Both ends are rounded for easy skidding. The lifting frame may be used to attach boom lines or hoist slings. The lifting frame is flush with the sides of the skid. Main runners, running the length of the skid, are strengthened by cross-members for additional rigidity. The frame is covered with a polyurea coating for corrosion resistance and has a diamond-patterned deck plate to provide a solid, skid resistant floor.
The swivel incorporates improvements such as interchangeable parts in key areas for economy and easy service. The compact, lightweight swivel-head design weighs 2,000 lb and fits a variety of drilling or workover masts. The design incorporates a reliable, custom-built drive train with hardened steel gears.
