  • Drill string constant velocity connection
    Patent number: 10267098
    Abstract: A constant velocity connection for use in a drill string can include at least one ball-and-socket joint, and an insert rotationally received in an opening formed laterally through a ball of the joint. A method of constructing a constant velocity connection can include installing an insert in an opening formed in a ball of at least one ball-and-socket joint of the constant velocity connection, and allowing the insert to rotate in the opening about a lateral axis. A drill string can include a drilling motor, a drill bit, and a constant velocity connection connected between the drilling motor and the drill bit, the constant velocity connection including at least one ball-and-socket joint, and an insert rotationally received in an opening formed laterally through a ball of the joint.

  • Directional drilling systems
    Patent number: 9556677
    Abstract: A directional drilling system for use in drilling a wellbore can include a bit deflection assembly with a bit axis deflection mechanism which applies a deflecting force to a shaft connected to a drill bit. The deflecting force may deflect the shaft, without being reacted between the deflection mechanism and the drill bit. The deflecting force may deflect the shaft between the drill bit and a radial bearing which maintains the shaft centered in the bit deflection assembly. The deflection mechanism may both angularly deflect and laterally displace the bit axis in the deflection mechanism.
