Abstract
A system for drilling at least one well of interest proximate a reference well comprises at least one sensor in a drill string in the at least one well of interest to detect at least one parameter of interest related to a distance and a direction to the reference well. A controller is operatively coupled to the at least one sensor to determine the distance and the direction from the sensor to the reference well based at least in part on the at least one detected parameter of interest. A steerable assembly is operatively coupled to the controller to receive commands from the controller to adjust the path of the at least one well of interest being drilled based at least in part on the distance and direction from the sensor to the reference well.
