  • Publication number: 20140174749
    Abstract: A tool for releasably coupling a coiled tubing string to a primary tubing string includes: a tool body for coupling to a downstream end of the primary tubing string, the tool body comprising a locking mechanism for selectively coupling a coiled tubing end joint to the tool body, the locking mechanism being unlockable in response to fluid pressure inside the tool body exceeding a first threshold; a wellbore access mechanism openable in response to fluid pressure inside the tool exceeding a second threshold.

  • Patent number: 7631694
    Abstract: A modular steam injection line, for use in steam assisted gravity drainage (SAGD) operations for delivery of an equal steam mass flow along a length of the apparatus, incorporates steam splitter modules fluidly connected for forming the steam injection line. Each of the modular steam splitters is fit with interchangeable nozzles for delivering steam to the formation. The interchangeable nozzles have orifices of different sizes and the nozzle orifice size required for each individual module to deliver an equal mass flow of steam from each module, at sub-sonic rates, along the entire length of the steam injection line.

Each of the modular steam splitters is fit with interchangeable nozzles for delivering steam to the formation. The interchangeable nozzles have orifices of different sizes and the nozzle orifice size required for each individual module to deliver an equal mass flow of steam from each module along the entire length of the steam injection line is calculated based on steam conditions at each module so that each module can be fit with nozzles having the appropriate sized orifices.

  • Patent number: 6666666
    Abstract: A pump comprises multiple, axially stacked positive displacement fluid device sections, such as circumferential piston pumps having chambers and contra-rotating chambers. The device can be similarly employed as a fluid motor. The stacked sections are arranged within an outer retaining barrel in one or more stages. The pump is particularly suitable for installation downhole in the casing of a wellbore. Each section comprises a pair of rotors fit to shafts which are rotatably supported on hard faced bearings between the shafts and the bosses. Each pump section draws fluid from an inlet port and discharges fluid to a common and contiguous discharge manifold. The inlets of the pump sections for a suction stage communicate with a fluid source. Cross-over sections route fluid between stages. Successive pressure stages draw fluid from the cross-over fit to the preceding stage's discharge manifold.

  • Patent number: 5310286
    Abstract: A glory hole silo comprising a cylindrical casing open at the upper end thereof; an upwardly open porch for supporting a flowline, said porch extending horizontally from and cantilevered with respect to said casing, the upper surface of said porch opening to the interior of said casing and provided with means communicating with the interior of said casing for attaching a flowline; and a removable roof extending over the open upper end of said casing and porch. The porch structure permits flowlines to be readily connected without the intervention of a diver.
