For the guy at the controls, driller Dave Ortman was skeptical at first about running 3 ½-inch pipe and has had to adjust his drilling technique. “With the T3W, I torque up the 4 ½-inch drill pipe to 3,500 lb at the top and 1,500 lb at the bottom. The 3 ½-inch can’t take that. I torque to 2,300 at the top and 1,200 at the bottom."
