High Torque Drill Rig to Cover All the Bases

When your work spans across the variable geology of the Northeast, finding equipment that balances power, compactness, and versatility is no small task. ODYSSEY ENVIRONMENTAL SERVICES found their answer in the Geoprobe^® 3135GT high torque drill rig.

"We needed a more powerful drill rig that is still somewhat compact for our jobsites and has the versatility to complete our demanding environmental and geotechnical projects," Jason Miller, vice president, said. "The machine we were looking for needed more head torque for spinning augers, but still allow us to run DPT, drill air and mud rotary, and rock core."

After evaluating options, the 3135GT fit the bill.

Productivity by Design

What surprised Odyssey most was how the rig's design translates directly into field efficiency.

"The side shift head allows you to always drill directly over the borehole without having to adjust the foot forward and back to change rods," Miller said. "With three winch lines, you can pull multiple tool strings at any given time."

The result is a streamlined workflow that simplifies tasks and speeds up production. The rig is user-friendly enough that one person could run it — similar to a 7822DT — but also simplifies fieldwork for the helper.

"It’s very operator-friendly and also user-friendly for helper to work with everything lining up directly over the borehole. By sliding the head, it makes it very easy to change drilling methodology," Miller said. "It simplifies tasks."

Features that Make the Difference

Two capabilities stand out above the rest.

• Six-speed Head: “Allows for drilling with augers easily in high torque drill situations, then easily switch over to core, and spin casing higher rpms when needed. With this head it allows you to dial head speed in to gain maximum bit penetration for drilling.”
• Three Winch Lines: “These are a game changer when hoisting and moving tools.”

Add in a track system that traverses varied terrain with ease, and the high torque drill rig handles whatever the jobsite demands.

High Torque Drill Built for Variable Conditions

Working throughout the Northeast means encountering unpredictable formations from one project to the next. The 3135GT's additional head torque keeps Odyssey productive regardless of conditions.

"The ability to change drilling methodology quickly helps us tackle difficult formations with ease," Miller said.

The rig runs daily on diverse projects spanning direct push, augers, air rotary, and mud rotary drilling — covering the full range of Odyssey's environmental and geotechnical work.

Simplifying Operations

Before the 3135GT, coordinating which rig went to which job added complexity. That's no longer a concern.

"The 3135GT allows us to be more diverse and not worry which rig is out on a job," Miller said. "It covers all the bases."

The bottom-line: "The 3135GT increased our capabilities, productivity, and profitability across the board," Miller said.

Service When It Counts

For the Pennsylvania-based company, the Geoprobe^® East Coast Service Center (ECSC) has become an essential partner.

"The ECSC is phenomenal. Having them so close is a blessing for us. We don't always have time to work on the rigs ourselves, so we can just run it to them," Miller said. "They understand how crucial it is to get equipment up and running in a timely fashion."
