ABSTRACT:
A method related to restarting a drilling process includes the steps of applying a surface torque to a drill string in a borehole, detecting signals related to one of a torque and a rotational speed experienced at a bottom hole assembly, initiating drilling fluid flow, and lowering a drill bit to a bottom of the borehole. The surface torque or the drilling fluid flow is maintained or changed based on the signals related to the torque or rotational speed.
