Systems, methods and apparatuses to aid with directional drilling through a subterranean formation are described. A model is provided that is indicative of: (i) one or more frictional forces at one or more contact points of the BHA and a wall of a non-linear borehole through a subterranean formation, (ii) one or more internal torques of the BHA between the one or more contact points, and (iii) one or more internal torques of the drill string between the one or more contact points. Based on the model, a toolface severity is determined for the drilling system, the toolface severity corresponding to a change in angular deflection for a change in applied weight-on-bit (WOB) of the BHA. A design is selected for the drilling system based on a comparison of the toolface severity to another toolface severity for a different design. Drilling may be performed by a drilling system having a bottom-hole assembly (BHA) optimized to reduce fluctuations in toolface orientation along a non-linear borehole.
A computer-implemented method of designing a drilling system having a bottom-hole assembly (BHA) and drill string, the method comprising:
A method of directional drilling through a subterranean formation, the method comprising drilling with drilling system having a bottom-hole assembly (BHA) optimized to reduce fluctuations in toolface orientation along a non-linear borehole based on one or more predictions for a rate of penetration, a weight-on-bit, and an angular deflection.
A computer program product for enabling a computer to assist with designing a drilling system, the program product comprising:
A system for enabling toolface control while drilling a borehole through subterranean formation, the system comprising:
