  • Tubing driven progressing cavity pump and method of pumping well fluid from a well
    Patent number: 7628209
    Abstract: A progressing cavity well pump system has a stator secured to a string of tubing. A drive head at the surface rotates the tubing and the stator. The pump rotor is held against rotation by an anchor mechanism. The tubing, stator, rotor and anchor mechanism are installed in the well in a single trip.

  • Method and apparatus for aligning rotor in stator of a rod driven well pump
    Patent number: 7201222
    Abstract: A progressing cavity rod-driven well pump utilizes a tag shoulder above a helical passage of the stator. The pump stator is located at the lower end of a string of tubing. The tag shoulder is more restrictive than a passage through the tubing. A pump rotor is secured to a string of rods and has a stop located above the rotor. The rotor is lowered on the rods until the stop lands on the tag shoulder. Then the operator lifts the rods and the rotor to accommodate for expected stretch during operation. By removing the rods and rotor, monitoring tools can be lowered through the tag shoulder and stator.
