Truck Mounted Cementing Equipment: Mobile Well Completion

Truck mounted cementing equipment is the most common type of cementing equipment in the oil and gas industry. It's built on a heavy-duty truck chassis, so you can drive it from well site to well site. It's mobile, versatile, and self-contained — everything you need to do a cement job is on the truck. That's why it's the standard for onshore cementing operations.

How Truck Mounted Cementing Equipment Is Built

A typical truck mounted cementing unit has these main components, all mounted on the truck chassis:

The Pumping Skid. This is where the cement pumps are. Most truck mounted units have two or three plunger pumps, driven by a separate diesel engine. The pumps are the heart of the unit — they push the cement slurry down the well. They can pump at 5,000-10,000 psi or more, depending on the size of the unit.

The Mixing Skid. This is where the cement slurry is mixed. It has a mixer, a water tank, and a cement hopper. Cement powder is fed from a bulk silo, mixed with water and additives, and pumped out continuously. Modern units have automatic density control, so the slurry density stays consistent throughout the job.

The Control Cabin. This is where the operator sits to run the unit. It has all the gauges, controls, and monitoring systems. Modern control cabins are air-conditioned, with good visibility and comfortable seats. The operator can control all the functions from the cabin.

The Manifold and Piping. This is the network of pipes and valves that connect the pumps to the wellhead. It lets you switch between pumps, control the flow, and direct the cement where it needs to go.

The Power Unit. This is the diesel engine that powers the pumps and the mixer. Most truck mounted units have a separate engine for the cementing equipment, so the truck's engine isn't running the pumps. That's more efficient, and it means you can keep the equipment running even when the truck is off.

Advantages of Truck Mounted Cementing Equipment

Truck mounted cementing equipment has several advantages:

- Mobile: You can drive it from well to well on public roads. It's fast and easy to move.
- Self-contained: Everything you need is on the truck. You don't need a bunch of support trucks following you.
- Fast to rig up: Once you're at the well site, you can rig up and start cementing in a couple of hours.
- Versatile: You can use it for all kinds of cementing jobs — shallow wells, deep wells, onshore locations, anywhere.

FAQ

Q: How big is a truck mounted cementing unit?
A: A typical truck mounted cementing unit is mounted on a 6x6 or 8x8 heavy-duty truck chassis. The whole truck is about 10-12 meters long, and it weighs 20-30 tons. It's big, but it's still mobile — you can drive it on highways and oilfield roads.
