Geothermal Drilling Rigs by Geoprobe®

Durable Ease for Fast Production

Mud or Air Rotary

Engineered to handle the speed of geothermal drilling - drilling multiple borings per day as compared to a single hole during a multiple-day process -  the DRILLMAX® geothermal drilling rig exceeds expectations in tough conditions. While geothermal drilling tends to prioritize overall rig size and weight, drilling speed, and cost per foot, options such as sandline winch or pipe spinner systems can be added to minimize equipment on your geothermal drilling job site.


When handling tough site conditions with one machine, consider Geoprobe® sonic for a quick and efficient geothermal drilling rig. The track-mounted geothermal drilling rig easily maneuvers on site and preserves the option for continuous sampling to characterize the subsurface, improving geothermal well design and construction. Minimize your geothermal development time and site clean-up costs by casing holes quickly without drilling mud using sonic.

“The DRILLMAX® took a beating but got right through it. We doubled our production speed with the stroke and pump. The way she forces plastic clay out of the hole was pretty unbelievable. The 20-foot stroke and speed of the tophead means it goes faster for a longer distance, good for plunging clay out of the hole.”

DM250 completes geothermal field installations

DM250 Water Well Drill Rig

Stroke and head feed resulted in completing 15 bores to 305 feet through tough, plastic clay 80 percent of the hole while simple operation meant one person ran DM250 drill rig while the other worked the mud cleaner prepping loops for installation.

DM450 stands up to test of geothermal drilling in tough Colorado conditions

DM450 Water Well Drill Rig

DM450 stands up up to the 'geo-pace' of multiple borings per day in the Colorado mountains installing geothermal loops, reportedly outproducing the combined footage of three other rigs on the geothermal job.

Drill rig can be outfitted as down the hole drill or mud rotary drilling rig

DM650 Water Well Drill Rig

Outfitted for air drilling or as a mud drill, the DM650 tackles deeper wells required for large residential, light commercial, or farm irrigation.
