  • Patent number: 9074437
    Abstract: An actuator for a subterranean tool is releasably retained by a collet. The actuation system features opposing actuation pistons with ports communicating to the tubing. The spaced ports are sequentially straddled for initial setting and a subsequent release using a predetermined applied pressure. The applied pressure overcomes the retaining force of the collet and actuates a one of two opposed pistons to set the tool, which is preferably a liner hanger. Upon shifting the actuation tool to communication to another port leading to an actuating piston pushing in another direction with applied pressure releases the tool and re-latches a retaining collet. The tool can be set, released and repositioned for another cycle in the same trip in the hole.

    Abstract: A stage tool operable with a plug is used for cementing a tubing string in a wellbore annulus. The tool can have a housing with a closure sleeve movably disposed in the internal bore of the housing. When pressure is applied downhole to the tool, a breachable obstruction on an exit port of the tool's bore opens and allows fluid such as cement slurry to communicate to the wellbore annulus. When cementing through the open tool finished, a plug deployed downhole lands on a seat in the closure sleeve, and applied fluid pressure in the tool's bore against the seated plug closes the closure sleeve relative to the housing's exit port. Rotational catches between the housing's bore and the closure sleeve prevent the closure sleeve from rotating. Preferably, an intermediate sleeve is used in the housing's bore and has rotational catches on each end.

  • Publication number: 20080223577
    Abstract: A foam delivery system comprises two delivery tubes providing a mixing chamber with a two-part polymeric foam. The mixing chamber mixes the two-part polymeric foam below a ground surface. A delivery manifold with delivery arms discharges the two-part polymer resin from the foam delivery system. A method of distributing a foam delivery systems comprises lowering a foam delivery system below a ground surface and discharging a polymer resin into the ground surface from a mixing chamber located below the ground surface. The mixing chamber discharges the polymer resin while the mixing chamber is lifted towards the ground surface, providing an expanding base of polymer resin. In that the chemicals are mixed at depth, that is, at the depth of the desired injection points, the possibility of premature setting and plugging of the delivery system is negated.

  • Patent number: 6834720
    Abstract: An improved method and apparatus for injecting particulate media into the ground for constructing underground permeable reactive barriers, which are used for environmental remediation of subsurface contaminated soil and water. A media injector sub-assembly attached to a triple wall drill string pipe sprays a mixture of active particulate media suspended in a carrier fluid radially outwards from the sub-assembly, at the same time that a mixing fluid is sprayed radially outwards. The media spray intersects the mixing spray at a relatively close distance from the point of injection, which entrains the particulate media into the mixing spray and ensures a uniform and deep dispersion of the active media in the surrounding soil. The media injector sub-assembly can optionally include channels for supplying compressed air to an attached down-the-hole hammer drive assembly for use during drilling.
