  • Patent number: 8157090
    Abstract: An organization system for a series of objects to be sequentially run downhole is disclosed. The preferred objects are spheres of progressively larger diameter put into a wellbore to land at discrete locations for operation of ports in a given sequence so that a specific producing zone or zones can be completed in increments that preferably go in an uphole direction as progressively larger spheres are inserted. In the preferred embodiment the process is fracturing where a series of ported subs are operated to selectively open for the fracture procedure at a specific location and then close or become isolated when another sphere is dropped. Optionally the balls can be recovered at the surface when production starts. The organizer prevents size confusion and gives a ready feedback as to the progress of a given job. Trays can be stacked and carried in a carrying case.

  • Publication number: 20110203805
    Abstract: A valving device includes a tubular having a wall including a passageway therethrough fluidically connecting an outside of the tubular with an inside of the tubular, a plug movable relative to the wall between a first position wherein the plug substantially prevents fluid flow through the passageway and a second position wherein the plug permits fluid flow through the passageway. At least one force failing member configured to maintain the plug in the first position until attainment of a selected force acts upon the plug, and movement of the plug is in a direction substantially parallel to a longitudinal axis of the tubular yet non-coaxial with the tubular.
