Truck- and trailer-mounted mobile drilling rigs rated to drill to 12,000 ft — the SK 775, SK 1000 and SK 1100 — each built to work over and complete wells as well as drill them.

A mobile drilling rig bores the original hole — it drills a new well rather than servicing one that already produces. Service King's drilling rigs are truck- or trailer-mounted, so they move between locations under their own power instead of being assembled on site like a conventional land rig. The SK 775, SK 1000 and SK 1100 also carry enough mast capacity to complete and work over wells, so a single unit can drill, complete and service — a real advantage for operators who would rather not run a separate rig for every job.
A drilling rig is the asset at the front of every well's life. Owning a mobile one keeps that work — and its revenue — in house:
Drilling rigs are big-ticket assets, which is exactly why financing makes sense: structured over a longer term to match the rig's earning life, so the payment lines up with the revenue rather than draining your capital. See what you qualify for or read how rig financing works.
Drilling depth is quoted by drill-pipe size, because thinner pipe reaches deeper. The SK 1000, for instance, drills to 8,000 ft with 4½" pipe or 12,000 ft with 3½" pipe — so match the rating to your target formations. Mast capacity, from 400,000 to 500,000 lb across these rigs, sets how much drill string and casing the rig can handle, and the carrier — a 7-axle truck mount or a 4-axle trailer option — affects how you move and permit it. Deeper, heavier programs point to the SK 1100; a versatile drill-and-workover unit is the SK 1000 or the SK 775.
A drilling rig bores the original well; a workover rig services and repairs a well that already produces. Service King's larger rigs do both — they drill, complete and work over — while the smaller SK models focus on well service and workover. See workover & well service rigs.
Up to 12,000 ft with 3½" drill pipe on the SK 1000 and SK 1100, and to 10,000 ft on the SK 775. Reach depends on drill-pipe size, so the same rig goes deeper with thinner pipe.
Yes. The SK 775, 1000 and 1100 carry the mast capacity to complete and service wells as well as drill them, which is why many operators run one rig across all three jobs.
