Small Rig, Strong Results on Injection Point Project

Running three, 10-day shifts, Hana Engineers and Consultants used their 6712DT and 7822DT to complete 300 injection points — up to 35-feet deep — on a chlorinated solvents remediation project in Marietta, Pennsylvania. Faced with varied rock, uneven terrain, and tight railroad access, the compact 6712DT emerged as the top performer.

“The 6712DT did more injection points than the 7822DT. It has all the power and hammering force of the 7822DT in a smaller platform, so it was easier to maneuver between injection points and lines on the ground,” Charles Sweet, operator, said. “The 6712DT had no problems getting to depth running 2.25-inch rods and was easy to keep work steady. I love that rig.”

Initially skeptical about the smaller rig, Sweet quickly changed his mind once he ran the controls.

“When I started four months ago, I looked at the 6712DT and wondered ‘what could it do?' I had a mentality that because it was smaller it couldn’t do much,” Sweet said. “Running it on the injections job, I understand it has a place in the company. I wasn’t lacking any power just because of the size. It’s a smaller platform with the same hammer and same pullback as the 7822DT. Nothing stuck. Not once did I regret running the 6712DT.”

Simple by Design Wins When Completing Injection Points

Sweet’s favorite 6712DT feature? Its simplicity.

“It doesn’t have a bunch of accessories or unneeded stuff,” Sweet said. “As a direct push platform, I could be more productive with the 6712DT because I didn’t have to swing the breakout or have the auto drop hammer in the way.”

Support That Stands Out

He credits Geoprobe^® for making “great, user-friendly machines that make everything easier in the field.” But for him, what sets Geoprobe^® apart is support.

“Anything that comes up, I can get someone on the phone and in one phone call, I can get the situation resolved,” Sweet said. “If I can’t fix it over the phone, then someone will come out right away and help keep the rig going.”

He’s especially appreciative of the technical expertise Geoprobe^® provides.

“I’ve dealt with Vic Rotonda [sales representative] for quite a few years. If I have a question about any type of tooling or drilling, he’s always pointed me in the right direction,” Sweet said. “They’re great people all around the board.”

Big Value in a Small Package

He now cautions against discounting Geoprobe^® rigs based solely on size.

“Even though Geoprobe^® rigs are small, they add big value and big benefit to any company,” Sweet said. “They add experience, knowledge, and service when you buy their rigs.”
