"Safety was the number one reason I switched to a TH60."
The company is located in Missouri's Mark Twain National Forest, operating at the edge of the Ozark Highlands 75 miles (121 km) southwest of St. Louis. So Felix had two qualifications for working at these locations. The rig must be small enough to fit on his customer's residential properties. And it had to be robustly built yet versatile for working the varying formation of shale and limestone.
Eye set the TH60 up this day for a residential well on a remote, rural property. He began with a 10-inch (254 mm) bit on a QL 80 DTH hammer, quickly punching through 16 feet of overburden containing thin sandstone bands in clay. He continued to 80 feet (24 m) in limestone and cased this upper section of the well profile with 6 ¼-inch PVC.
After casing was installed, he grouted using 14 bags of bentonite chips and continued to drill the production hole using a COP 64 hammer with a 6 inch concave face bit to a total depth of 180 feet (54.9 m) yielding 40 gpm (151 L/min.). Eye then air-flushed the well as his team cleaned the work area and gave the rig a quick washdown.
By the time they were ready to trip out and pack up, the well produced near-perfect water with no sediment. No longer than 20 minutes had passed until the brightly lit mast quietly descended, and the crew packed up.
Eye climbed into the cab, smiled, and said, "Days like this make me thankful for owning this TH60."
