The D-Tech next-generation RST675 successfully drilled a one-run vertical, curve, and lateral for an operator in the Rockies, making it the first monobore achieved with the D-Tech Rotary Steerable tool.

The BHA, which included the RST675, an 8 1/2-in. Ulterra drill bit, and a BICO mud motor, drilled 16,257 feet with an overall rate of penetration of 135 ft per hour. The curve was built on 7s and 8s with a toeup lateral design. This was achieved by reducing the cutter-to-piston distance by 50%.
