Implementation issues concern operators
For simultaneous drilling and reaming operations, Cambridge Drilling Automation's automated guidance system has achieved impressive results including a single 7,100 ft run for Amoco Corp. The tool configuration includes a 121/4-in. hole size followed by a 14-in. reamer (Fig. 3). Because rotary-steerable technology performs quite differently from steerable motors, the operator must address implementation issues in order to use the most appropriate system.
