Abstract

System for anchoring and orienting a tool at a targeted depth and recording its angular position comprises a casing assembly including coupling joints; a position pilot joint having an anchor sleeve, guide block and spline teeth, the guide block and spline teeth resiliently supported to retract into and extend out of the sleeve. The spline teeth are attached to a synchronizing mechanism for maintaining the spline teeth in a retracted position until each spline tooth is aligned with corresponding coupling joint's recesses. As the guide block travels along the angled ramp of a coupling joint and enters the guiding slot, the position pilot and stabilizer joints correspondingly rotate. When the position pilot joint passes through its corresponding coupling joint, the spline teeth extend out of the anchor sleeve to engage the recesses. An azimuth joint is configured to record the angular orientation of the tool once the tool is anchored.
