Efficiency Plus Simplicity Equal Performance


Lightweight DM250 outperforms bigger rigs, using less fuel and increasing maneuverability on tricky residential water well drilling sites.

Lightweight DM250 outperforms bigger rigs, using less fuel and increasing maneuverability on tricky residential water well drilling sites.

A second-generation residential well drilling business began in 1985, Rosendall Well Drilling in Michigan realized increased demand for their residential well drilling services as new construction took off. A small company with five employees, owner Jeff Rosendall was considering updating his aging rig when Donnie Wood, general manager, stopped by to introduce DRILLMAX® by Geoprobe®. Other drillers in the area had recently added DRILLMAX® by Geoprobe® rigs to their fleets, so Rosendall had ready access to reviews.

“I inquired with other local drillers who were happy with their DRILLMAX® by Geoprobe®,” Rosendall said.

Rosendall was no stranger to Geoprobe®/DRILLMAX® equipment. When he decided several years ago to diversify his business to include environmental drilling, he launched this new service line by purchasing a used Geoprobe® 7822DT.

“After three years there was enough demand we bought a new Geoprobe® 7822DT,” Rosendall said.

Now he too is among those happy with their DRILLMAX® by Geoprobe® purchase. He is impressed by the performance that comes from the smaller rig.

“It outperforms our older rig that is three times its weight,” Rosendall said. “The faster rotation speed and faster head movement up and down increases efficiency. It’s easy to operate — thanks to the layout of the control panel — and maneuver so we do more work in less time.”

Fuel usage also contributes to overall efficiency.

“The DM250 uses less fuel which is increasingly important as prices continue to rise,” he said.

He’s also come to appreciate the efficiency and simplicity of the rod carousel. On his older rig, he would have to look up to watch where the head was on the mast in order to determine when to slide it over to pick up drill pipe out of the rod carousel. 

“On the DM250, when head reaches positive stop at top, you know it's time to slide over to pick up the rod,” Rosendall said. “It makes it easier to use and takes the guess work out of it for more efficient drilling.”

Overall, the DM250’s capabilities and ability to access residential water well drilling sites have met Rosendall’s needs.

“Almost every job we do I’m impressed with how well things go,” he said. “It has outperformed the big rig I had with better performance and faster response.”
