What is a workover rig?

A workover rig is a mobile, truck-mounted unit that services a well after it has been drilled and completed. It pulls rods, tubing and pumps, cleans out the wellbore, swaps downhole equipment, and handles the remedial work that keeps a well producing. It is different from a drilling rig, which bores the original hole — and it does more than a light pulling unit, because a full workover rig carries the mast capacity and depth to reach and repair deeper wells. Well service rigs and workover rigs are grouped together here because Service King builds them on one platform, sized by how deep they reach and how much the mast can hold.

What a workover rig does — and why owning one pays off

Every day a well sits down waiting on a rig is a day it is not producing. Running your own workover rig puts that schedule in your hands instead of a service company's queue:

  • Faster response — mobilize to your own wells on your timeline, not someone else's backlog
  • More revenue captured — a rig on location earns day rate and cuts a well's downtime
  • Full well control — pull and reset rods, tubing and pumps, clean out sand, and fish stuck equipment without subbing it out
  • One rig, many jobs — routine maintenance, completions and remedial work all run off the same unit
  • An asset that earns — a rig you own builds equity while it works, instead of being a cost you rent

The catch is the up-front price — and that is where we come in. Financing spreads the cost across the day-rate work the rig earns, so your cash stays free for crews, fuel and mobilization. See what your rig qualifies for or read how rig financing works.

How to choose the right rig

Two numbers in the table above tell you most of what you need. Service depth is how deep the rig can run tubing and rods — match it to your deepest well, with room to spare. Mast capacity (rated in pounds, with 4 or 6 lines) is how much weight the derrick can pull, so heavier strings and deeper wells call for a higher number. The carrier — from a 3-axle up to a 6-axle truck — affects road weight and how you set up on location. A shallow-well operator is well served by an SK 175 or 275; a deeper program leans toward the SK 575 or SK 675. Not sure where you land? Tell us your well depths and we will help you match the rig.

New or used?

Both are financeable. A new rig comes with known specs, a warranty and clean records. A used rig can put a unit on location faster and for less — just weigh the year, hours, mast condition and last recertification. Either way the financing works the same, and a well-kept used rig is a common way to add capacity without waiting on a build slot.

Workover rig FAQs

What is a workover rig used for?

Servicing and repairing producing wells — pulling rods and tubing, changing pumps, cleaning out the wellbore, fishing stuck tools, and completing or recompleting zones. It keeps existing wells producing rather than drilling new ones.

How much does a workover rig cost?

It ranges widely with size and condition — a smaller used single can run into the low six figures, while a large new rig reaches seven. What usually matters more is the monthly payment, which financing sizes to the day-rate work the rig earns. Ask us for a payment estimate.

What size workover rig do I need?

Size it to your deepest well and heaviest string. Shallow wells are handled by the SK 175 to 375; wells past 12,000 to 16,000 ft point to the SK 575 or SK 675. Match service depth first, then mast capacity.

Can I finance a workover rig, new or used?

Yes — both. Rig financing is asset-based, so the equipment carries much of the deal. See how rig financing works, then apply once to get matched.
