  • Directional drilling using a rotating housing and a selectively offsetable drive shaft
    Patent number: 9957755
    Abstract: Example systems described herein may include a housing 201 and an offsetable drive shaft 202 coupled to a drill bit 203 and at least partially disposed within the housing 201. The offset angle of the offsetable drive shaft 202 may determine an angle of the drill bit face. A motor 204 may be coupled to the housing 201 that, when activated, independently rotates the housing 201. By independently counter-rotating the housing 201 relative to a drill string during drilling operations, the angular orientation of the offsetable drive shaft 202 and drill bit 203 may remain geo-stationary with respect to the surrounding formation, without requiring that the housing 201 engage a borehole wall.
