1. A system for forming a subsurface wellbore, comprising:
- at least one existing tubular coupled to a drill bit in the subsurface wellbore;
a rack and pinion system comprising a chuck drive system;
a second tubular coupled to the chuck drive system and configured to be coupled to the at least one existing tubular; and
an automatic position control system comprising at least one measurement sensor attached to the rack and pinion system, wherein the automatic position control system is configured to continuously assess relative rotation of the second tubular and the at least one existing tubular while drilling and control a position of the second tubular using the rack and pinion system.

Abstract
A system for forming a subsurface wellbore includes a rack and pinion system including a chuck drive system. The chuck drive system operates a drilling string. An automatic position control system includes at least one measurement sensor coupled to the rack and pinion system. The automatic position control system controls the rack and pinion system to determine a position of the drilling string.

10. A method for forming a subsurface wellbore, comprising:
-
forming a wellbore in a subsurface formation using a drill bit coupled to at least one existing tubular in the subsurface wellbore; continuously receiving, while drilling, position data about a second tubular from at least one measurement sensor attached to a rack and pinion system and coupled to an automatic position control system, wherein the position data comprises relative rotation of the second tubular and at least one existing tubular; and controlling a direction of the second tubular in the subsurface formation using the rack and pinion system coupled to the second tubular based on the position data from the measurement sensor. - View Dependent Claims (11, 12, 13, 14, 15, 16)
