  • Patent number: 10443377
    Abstract: A pressure test system for use in downhole fluid injection includes a shear plug assembly disposed along a flow path defined in a sump housing. The sump housing also includes a sump cavity positioned downstream of the shear plug assembly. A shear element of the shear plug assembly secures the shear plug assembly in a first position within the flow path, so that the shear plug assembly blocks fluid flow through the sump housing. Following a pressure test, fluid pressure on the shear plug assembly may be increased until the shear element of the shear plug assembly shears, after which, the pressurized fluid drives the shear plug assembly into the sump cavity, permitting flow to bypass the sump cavity through bypass channels. The bypass channels and other flow paths may be arranged to function as a pressure wave muffler in order to protect pressure sensitive components after shear out.

  • Patent number: 8225865
    Abstract: An apparatus for aligning a component includes: a downhole sub including a plurality of first axially extending tapered members, the plurality of first axially extending tapered members configured to engage a plurality of second axially extending tapered members of a downhole carrier in an interlocking engagement and prevent rotation of the downhole carrier relative to the downhole sub.

  • Patent number: 5544369
    Abstract: A portable shower system which when disassembled is stored in its own base, to define a suitcase-like base enclosing all of the support, curtain, and hose structure for transport when not in use, and expandable to a full height, fully enclosed shower stall. The shower stall may use a variety of water sources, either by a gravity fed shower bag, or by a pressure fed system. A compartment in the hollow base serves as a waste water collection chamber. Disposal of waste water can be done by either sealing the base and transporting to a waste disposal area, or connecting a hose to the discharge port, and directing the waste water away from the front of the shower, as well as other means of evacuating waste water from the base. The shower stall may also be used as a privacy room for changing clothes or as a restroom stall, when used in conjunction with a portable toilet. The shower stall may also be used as a decontamination unit when used with optional equipment.
