A hybrid Rotary Steerable System (RSS) includes both exterior steering pads as in a push-the-bit system and, internal shaft pistons as in a point-the-bit system. The steering pads and the shaft pistons may cooperate to permit the RSS to achieve tighter turning radii. The steering pads and the shaft pistons may be independently or collectively controllable by diverting a portion of drilling fluid flowing through the RSS. In some embodiments, the steering pads and shaft pistons may extend in opposite directions to steer the drill bit, and on other embodiments, the steering pads and shaft pistons may extend in the same direction.

Various downhole tools, such as drilling motors, drilling tools, reamer tools, casing reamer shoes, and related methods of installation, assembly and use. Casing reamer shoes and drilling reamers or motors may have internal impellers, progressive cavity pumps, hollow rotors and other parts, universal joints, and other features. A progressive cavity section may have a rotor and a stator. Rotor contacting surfaces of the stator, and stator contacting surfaces of the rotor, may be rigid during use. The stator contacting surfaces and the rotor contacting surfaces may be made of metal. After the casing is run, the casing is cemented and the reamer shoe drilled out.
