Derex 1340-12X DR

Navigate the toughest job sites

The Derex 1340-12X DR drilling rig is the perfect solution for your next geothermal, RC exploration or water well drilling project.

As experienced drillers, we understand that dealing with tough terrain is part of the job. Which is why we developed the 1340 DR drill on the Acela Monterra 4X4. Not only will this new drilling rig help you achieve your production goals, but it also opens up areas previously unreachable. This truck also features no emission controls, which will give you the confidence that you won’t encounter any unexpected shutdowns.  

The Derex 1340-12X Dual Rotary drilling rig will come with welder, drill pipe, down hole hammer and all change overs needed to drill.
