Cementing Equipment and Cementing Units: Where They're Used
Cementing equipment and cementing units are used everywhere there's oil and gas well completion. Every oil and gas well needs to be cemented — that's how you seal the wellbore, protect the casing, and make the well safe. Whether it's a shallow onshore well, a deep offshore well, or a horizontal shale well, you need cementing equipment to do the job.
Where Cementing Equipment Is Used
Cementing units are used in all the major oil and gas producing regions:
- North America: The US and Canada have the most active onshore drilling industry in the world. Every well drilled needs cementing, so there are thousands of cementing units working in North America at any given time.
- Middle East: Saudi Arabia, Iraq, UAE, Kuwait, Oman — the Middle East has some of the biggest oil fields in the world. They need lots of cementing equipment to develop and maintain their wells.
- Russia and the Caspian: Russia has a huge onshore oil and gas industry, with lots of cementing activity.
- Asia Pacific: China, India, Indonesia, Australia — Asia Pacific has growing onshore oil and gas production, and demand for cementing equipment is increasing.
- South America: Venezuela, Brazil, Argentina, Colombia — South America has significant onshore oil reserves, and they're developing them.
- Africa: Nigeria, Algeria, Libya, Angola — Africa has growing onshore oil and gas production.
Who Uses Cementing Equipment?
Cementing equipment is used by:
- Oilfield service companies: Companies like Halliburton, Schlumberger, Baker Hughes, and others. They own fleets of cementing units, and they provide cementing services to oil companies. Most small oil companies don't own their own cementing equipment — they hire a service company to do it.
- Large oil companies: Some big oil companies own their own cementing fleets, especially in regions where service companies are scarce. They have their own cementing units, operated by their own crews.
- Independent operators: Some small independent operators own their own cementing units, especially if they have a lot of wells in a small area. It's cheaper to own your own equipment than to hire a service company every time.
What Kinds of Cementing Jobs Are There?
Cementing equipment is used for all kinds of cementing jobs:
- Primary cementing: The initial cement job, when you run the casing and cement it in place. This is the most common cementing job.
- Remedial cementing: Fixing a cement job that failed. If the cement has gaps or leaks, you pump more cement in to fix it.
- Squeeze cementing: Pumping cement through perforations, to seal off a zone or fix a leak.
- Plug and abandonment: Cementing a well that's no longer producing, to plug it permanently.
FAQ
Q: How many cementing units does a typical service company have?
A: A small cementing service company might have 5-10 cementing units. A medium-sized company might have 20-50. A big international service company might have hundreds of cementing units, working all over the world.
