Twin Pump Cementing Units: The Industry Standard
A twin pump cementing unit is the most common type of cementing unit in the oil and gas industry. It has two pumps — so you always have a backup — and it's powerful enough for most onshore cementing jobs. If you're starting a cementing service company, a twin pump unit is the first rig you should buy. It's the sweet spot of the cementing unit market.
Where Twin Pump Cementing Units Are Used
Twin pump cementing units are used everywhere there's onshore oil and gas well completion. They're the workhorses of the cementing industry. You'll find them:
- On every onshore drilling rig: When a well is ready to be cemented, a twin pump cementing unit shows up to do the job.
- At every oilfield service yard: Cementing service companies have fleets of twin pump units, ready to go to any well site in the region.
- In every oil-producing region: North America, the Middle East, Russia, China, South America, Africa — everywhere there's onshore oil and gas, there are twin pump cementing units working.
Why Twin Pump Is the Standard
Why is the twin pump cementing unit the industry standard? Because it hits the sweet spot:
- Backup pump: If one pump breaks down, you have another one to keep the job going. That's critical — you can't afford to stop a cement job halfway through. If the cement starts setting in the casing, you've got a big problem.
- Enough power: Two pumps give you enough pumping power for most onshore wells. You can pump at 5,000-10,000 psi, which is enough for most wells up to 4,000-5,000 meters deep.
- Affordable: A twin pump unit is more expensive than a single pump unit, but it's not that much more. And the extra reliability is worth the money.
- Versatile: A twin pump unit can handle all kinds of cementing jobs — primary cementing, remedial cementing, squeeze cementing, plug and abandonment. It's a one-size-fits-all machine.
What Kinds of Jobs Can a Twin Pump Unit Do?
A twin pump cementing unit can handle:
- Primary cementing: Cementing the casing in a new well. This is the most common job.
- Remedial cementing: Fixing a cement job that failed.
- Squeeze cementing: Pumping cement through perforations to seal off a zone.
- Plug and abandonment: Cementing a well that's no longer producing.
- Cement plug drills: Drilling through cement plugs when you need to go back into the well.
FAQ
Q: What size twin pump cementing unit should I buy?
A: If you're just starting out, a medium twin pump unit — with two 500-700 horsepower pumps — is a good choice. It's powerful enough for most onshore wells, but not so big that it's expensive. You can always upgrade to a bigger unit later, as you get bigger jobs.
