  • Patent number: 7011156
    Abstract: A percussion apparatus and method of using the percussion apparatus. The apparatus may be used for delivering an impact to a tubular string. The apparatus comprises a cylindrical member having an internal bore containing an anvil and a first guide profile. The apparatus further includes a rotor disposed within the internal bore, and wherein the rotor member comprises a body having an outer circumference with a second guide profile thereon, and wherein the rotor contains a radial hammer face. In a first position, the second external guide profile of the rotor will engage with the first guide profile of the cylindrical member so that the radial hammer face can contact the anvil. In a second position, the second guide profile of the rotor will engage with the first guide profile of the cylindrical member so that the radial hammer face is separated from the anvil shoulder. Multiple rotors and multiple stators may be employed. The rotor may be operatively associated with a stator that directs flow into the rotor.

  • Patent number: 6966373
    Abstract: An inflatable sealing assembly integrated with a flow carrier which seals the inside of the flow carrier upon detection of a physical condition (e.g. fluid pressure). The inflatable sealing assembly includes a housing, a compartment in the interior of the housing for storing an inflatable sealing device, an inflating mechanism, and a sensor. Upon detection of the physical condition in the exterior and/or interior of the flow carrier, the sensor activates the inflating mechanism, preferably automatically, to inflate and deploy the inflatable sealing device which seals off the inside of the flow carrier. The inflatable sealing device may be an air bag.

  • Patent number: 6955705
    Abstract: Method and system for compressing and dehydrating wet natural gas produced from a low-pressure well using a rotary screw compressor. A dehydrating agent is combined with wet natural gas within a rotary screw compressor. Operation of the rotary screw compressor causes compression and dehydration of the wet natural gas to produce a compressed dry natural gas. Engine exhaust produced by the engine which powers the rotary screw compressor may be used to remove water absorbed by the dehydrating agent and thereby recover the dehydrating agent for re-circulation in the system.

  • Patent number: 6808354
    Abstract: A multi-screw auger equipped tank comprises opposing sides sloping downward and inwardly toward one another. A plurality of shaftless screw transfer augers run along the tank bottom. Drivers and transmissions coupled to the transfer augers permit simultaneous rotation of the augers in the same or opposite directions of rotation, at the same or different rotational speeds. Materials within the tank, typically slurries or sludges, can be moved to one end of the tank by the transfer augers. An inclined screw auger is disposed near the end of the tank distal from the location at which materials are deposited in the tank. The inclined screw auger picks up the materials and moves them out of the tank. Baffles in the tank aid in dewatering slurries and sludges. Circulation of materials within the tank may be done by rotating the transfer augers in different directions and/or rotational speeds.
