  • Patent number: 9797210
    Abstract: A milling-drilling section billet and anchoring device that is an improvement over current technology. The invention provides a device that incorporates an aluminum milling-drilling section billet and an anchoring device. The assembly is segregated into three main functional components: a setting tool connector system, an aluminum billet, and an anchoring section. The anchoring section has two slips, offset laterally and positioned 180 degrees apart on the device. When deployed, the slips lock the device in the formation and produce an offset of the billet within the formation. This angular positioning allows a milling head to be moved in a new direction from the existing well formation. Once the device is properly positioned in the wellbore, a frangible member breaks to allow removal of the setting tool prior to the renewed drilling operation.

  • Patent number: 8739879
    Abstract: A series of sliding sleeves is actuated by a single ball that lands on a first ball seat and shifts the ball seat. The shifting of the ball seat also allows tubing pressure to communicate to a formerly atmospheric chamber on one side of a piston integrated into the back side of the sliding sleeve. The other side of the piston remains at atmospheric pressure so that the shifting of the ball seat not only releases the ball to go to the next ball seat but also puts a net force on the sliding sleeve to shift it against a travel stop to open a port to allow fracturing, even if there is cement in the annulus around the opened port.
