Abstract:
A drilling apparatus includes a progressive cavity device that includes a plurality of linearly coupled rotors. Each rotor is disposed in a separate stator. Adjoining stators are separated by a coupling device configured to provide lateral support to the rotors. The stators may be enclosed in a common housing. The adjoining stator sections may be rigidly connected to each other.
