Buying an Oil Well Drilling Rig

Buying an oil well drilling rig is one of the biggest investments you can make in the oil and gas industry. A new onshore drilling rig can cost $10-50 million, and the operating costs are millions of dollars a year. It's not a decision to take lightly. Whether you're an independent operator, a drilling contractor, or a small oil company, here's what you need to know to get the right rig for your needs.

New vs. Used: The Big Decision

Buy New If: You're a major drilling contractor, you need the latest technology, you have the budget, and you want a warranty and factory support. New rigs come with the best equipment, computerized controls, and the latest safety features. But they're expensive, and you lose a lot of money the second you take delivery.

Buy Used If: You're a small operator, you're on a tight budget, or you just need a rig that works. Used drilling rigs can be 30-50% cheaper than new. But you have to do your homework. Bring a drilling consultant or a senior driller with you to inspect any used rig before you buy. You want to know exactly what you're getting into.

What to Check on a Used Rig

When you're looking at a used drilling rig, check these things:

- Engine hours: How many hours on the main engines? Engines are expensive to overhaul.
- Drawworks condition: Is it worn? Are the brakes in good shape?
- Mast condition: Are there cracks, especially at the welds?
- Hydraulic system: Any leaks? Do all the functions work properly?
- Service records: Has the rig been maintained properly? Can you see the records?
