7822DT v3 Enhancements Make Everyone Happy

With three offices — one each in New York, Pennsylvania, and North Carolina — Parratt Wolf has a fleet of 30 rigs, seven of which are Geoprobe®. The 53-year-old company got its start doing primarily geotechnical work before expanding into environmental in the 1980s. Now their more than 50 employees complete 90 percent environmental.

“We have highly-trained crews who do more specialty work than geotechnical,” Todd Muench, operations manager, said.

Having had great success with their other 7822DT rigs and experiencing business growth, they didn’t consider options other than a 7822DT v3 when replacing an outdated truck rig without an SPT hammer.

“It’s more compact than the older truck rig yet does 85 percent of what a full-size rig would do,” Muench said. “We were seeking efficiency and power in the probe hammer.”

Choosing the versatile 7822DT v3 to do direct push, auger, air rotary, and mud rotary, Muench immediately identified drilling rig equipment enhancements on the v3 compared to their older models. These include wider tracks going from 60-inches to 70-inches.

“This is an advantage since we use it like an ATV not just a track machine,” Muench said.

He also appreciates the fuel savings realized from the auto throttle and Tier 4 engine.

“V1 functions would stall when at idle, now we can tower up at idle rather than half throttle,” Muench said. “Tier 4 engine operates functions at idle for additional fuel savings.”

The reorganization of where drilling rig equipment options are located is another benefit. 

“By stacking the extruder and Moyno pump on one side of the machine, we chose a rod rack for opposite side and then use front rack for augers,” Muench said. 

All these enhancements have added up to satisfaction in their purchase.

“Everyone’s been happy,” Muench said. “More than just being new and shiny, it’s just more user-friendly.”

7822DT v3 Drilling Rig Equipment Advantages Compared to Legacy Models

Parrat Wolf Operations Manager Todd Muench identified several enhancements on the 7822DT v3 proving beneficial compared to their legacy 7822DT.

• Wide tracks — going from 60 inches on v1 to 70 inches on v3
• Stability — drill mounted more forward on carrier increases stability
• Auto throttle — returns to idle for fuel savings
• Remote control — more user-friendly
• Option mountings — extruder and moyno on same side leaves other side for other options 
• Fuel filter — full-size, spin is easier to access than inline on previous version
