  • Rim-driven propulsion pod arrangement
    Patent number: 6837757
    Abstract: In the embodiments described in the specification, a rim-driven propulsion pod arrangement has a cylindrical housing with a duct providing a flow path for water and a rotor assembly supported from a central shaft and containing a rotating blade row and driven by a rim drive permanent magnet motor recessed in the housing. An array of vanes downstream from the rotating blade row is arranged to straighten the flow of water emerging from the rotating blade row. Radial bearing members on the rotor have a hardness less than that of the shaft on which the rotor is supported and relatively soft protrusions are provided in the space between the rotor and the housing to limit excursion of the rotor. A thrust bearing has wedges arranged to form a water wedge between facing surfaces of the rotor and the rotor support during rotation of the rotor.

  • Cyclic check valve for coiled tubing
    Patent number: 6834722
    Abstract: A cyclic check valve is provided for a coiled tubing string which enables reverse circulating for a specific period when a specific combination of pumping condition and oil conditions are favorable. The check valve may be activated to prevent reverse flow up through the valve and into the coiled tubing in the event of a failure of the coiled tubing at surface. The valve may be de-activated to allow reverse circulating. The check valve includes a flapper valve which may be de-activated by shiftable sleeve locked in place by a J-slot assembly. The check valve may be cycled from the activated to de-activated position and verified by a change in pressure drop through the tool.

  • Bottom hole assembly
    Patent number: 6832654
    Abstract: A bottom hole assembly for use with fracturing or fracing a wellbore using coiled tubing is described having a first packing element and a second packing on a mandrel. The bottom hole assembly may be run into the wellbore such that the packing elements straddle the zone to be fraced. Also described is a timing mechanism to prevent the closing of dump ports before the bottom hole assembly may be flushed of the sand. A release tool is described that allows an operator to apply force to the coiled tubing to dislodge a bottom hole assembly without completely releasing the bottom hole assembly. Also disclosed is a collar locator capable of being utilized in a fracing process. Methods of using the above described components are also disclosed.

  • Method for cleaning gravel packs
    Patent number: 6832655
    Abstract: A method for cleaning a plugged gravel pack in a subterranean wellbore is provided. The method comprises the steps of using a pressure pulsating jet and a tangential vortex to deliver a pressure pulsating treatment fluid into the gravel pack wherein soluble plugging materials in the gravel pack are dissolved by the treatment fluid and insoluble plugging materials are moved through the gravel pack and circulated out of the wellbore. The treatment fluid is driven into the gravel pack to dissolve soluble fines and displace insoluble fines from the interstitial pore spaces of the gravel pack.
