Abstract
An apparatus for detecting and properly orienting a hydraulically-actuatable tool in a borehole and commencing drilling in a single trip of the drill string includes an MWD subassembly, for sensing the orientation, and a bypass valve for setting the hydraulically-actuatable tool once it is properly oriented and for thereafter conducting the drilling fluid to the cutter assembly. The method of setting a hydraulically-actuatable tool and commencing drilling in a single trip of the drill string includes the steps of running the hydraulically-actuatable tool into the borehole on a drill string which includes an MWD subassembly, sensing the orientation using the MWD subassembly, orienting the drill string to the desired orientation, and setting the hydraulically-actuatable tool.
