Cutting samples had come up soft in a couple places. Moore made the call to line this hole with 4 ½-inch PVC to prevent any sloughing, perforating the bottom 40 feet.
The rate at which M-K trips out with the Diamondback keeps M-K’s helper Coe busy. They used the rig’s heavy-duty, 18,000-pound winch to pull up the pipe. The DB series offers 18,000- and 30,000-pound winch options for the deep hole version. With the Diamondback driller’s controls, Moore is able to both extend the table fork into place holding the pipe downhole as well as control the hydraulic break out wrench. Once the pipe is broken loose, the helper swings in the optional pipe spinner to hydraulically spin off the pipe in a matter of seconds, saving both time and effort on each joint. Nearly 700 feet of pipe was racked in record time for M-K. Moore pulled out the conductor and sealed the top 20 feet of casing with bentonite clay.
"The Epiroc DB40 has more than lived up to its billing."
