Mobile Drilling Rigs: When Mobility Matters Most

A mobile drilling rig is any drilling rig that can be moved quickly between well sites without major disassembly. This includes truck-mounted rigs, trailer-mounted rigs, and even track-mounted rigs. The whole point of a mobile rig is to save time: the faster you can move from one well to the next, the more wells you can drill in a season.

Types of Mobile Drilling Rigs

Truck-Mounted Rigs. These are the most common mobile rigs. Built on a commercial truck chassis, they can drive on public highways at normal speeds. They're perfect for operations where you're drilling multiple wells in a region and need to move every few days.

Trailer-Mounted Rigs. These are rigs built on a trailer, pulled by a separate truck tractor. They're more flexible than truck-mounted rigs — you can swap out the tractor, and you can leave the rig on site while the truck goes and does other work. But they're not as maneuverable in tight spaces.

Track-Mounted Rigs. These are rigs on tracks, like a small crane. They're used in really rough terrain where wheeled vehicles can't go — swamps, steep hills, deep mud. They're slow on roads, but they can go places no other rig can.

When Should You Choose a Mobile Rig?

If you're drilling just one well and staying there for months, a skid-mounted rig is cheaper and makes more sense. But if you're doing development drilling (multiple wells in a field), workover operations, or exploration in remote areas, the mobility of a truck rig will pay for itself quickly. The time you save on rig-up and rig-down adds up to a lot of extra revenue over a year.

FAQ

Q: What's the maximum speed of a mobile drilling rig on the highway?
A: Most truck-mounted rigs can go 80-90 km/h on paved roads, same as a heavy truck. Just remember that the rig is tall and heavy, so you have to watch overhead obstructions and take corners slower.
