Patent ID: 8899352

Claim:
A system for controlling a drilling system configured for drilling a borehole in an earth formation, comprising: the drilling system, wherein the drilling system comprises a drill-string coupled with a bottomhole assembly, and the bottomhole assembly comprises a drill bit; an interaction element rotatably coupled with the drilling system, wherein: the interaction comprises a gauge pad assembly disposed circumferentially around the drilling system; the gauge pad assembly defines an interaction silhouette having a first area, and the drill bit defines a cutting silhouette having a second area, such that at least one of a size or location of the first area is different from a size or location of the second area; the gauge pad assembly is held geostationary in the borehole during operation of the drilling system; and the gauge pad assembly is disposed proximal to the drill bit at a distance of about 3 meters or less; and a controller configured to rotate the interaction element around the drilling system to change the interaction silhouette.
