To perform a pipeline bore as efficiently as possible beneath a busy West Texas highway, Hard Rock Directional Drilling decided to use a drill on each side of a planned intersection near the middle of the bore. The Vermeer D 1000x900 was set up on the Midland side of the bore path, and on the exit side, the crew used a Vermeer D500x500. The drills were outfitted with 8-inch (20.3-cm) mud motors and 123/4-inch (32.3-cm) bits to get the pilot bore through sandstone and limestone. At an average depth of 60 feet (18.3 m), it took 12 days for crews to complete the initial bore.
