  • Cementing tool
    Patent number: 10060219
    Abstract: An improved cementing tool is presented which allows for relatively easy removal and insertion of the tool through the use of non-threaded low-torque connections. The cementing tool uses a combination of threaded connections and non-threaded, low-torque connections configured to create a stack of components including plug launchers, ball launchers and plug launch indicator/counters. Use of non-threaded low-torque connections allows for breaking down the tool by hand, requiring no special torquing equipment.

  • Method and apparatus for downhole fluid conditioning
    Patent number: 9080443
    Abstract: A down hole fluid conditioning assembly, includable within a drilling bottom hole assembly or other tool configuration, creates a vortex to separate fluids such as drilling mud and the like into a lower density first portion and higher density second portion. The lower density first portion is directed toward the bottom hole assembly or other equipment to improve operational performance of the bottom hole assembly or other equipment. The higher-density second portion is directed away from the bottom hole assembly or other equipment, typically into a well annulus with an upward velocity component.
