SYSTEM, APPARATUS AND METHOD FOR GUIDING A DRILL BIT BASED ON FORCES APPLIED TO A DRILL BIT, AND DRILLING METHODS RELATED TO SAME

摘要

The present disclosure relates to a system, apparatus and method for guiding a drill bit based on forces applied to a drill bit, and drilling methods related to same.

主权项

1. A method for guiding a drill bit carried by a drill string, the drill bit configured to define a borehole in an earthen formation during a drilling operation, the method comprising the steps of:
causing the drill bit define the borehole in the earthen formation along a planned well path; obtaining, via at least one sensor assembly positioned proximate to or substantially aligned with a portion of a drill bit along a direction that is perpendicular to a central axis of the drill string, measurements indicative of one or more forces applied to the drill bit that has caused the drill bit to deviate off of the well path; and based on the measurements indicative of the one or more forces applied to the drill bit, guiding the drill bit in order to define the borehole along the planned well path.
