  • Patent number: 7717182
    Abstract: Well pumping of fluids having low hydrostatic pressure is provided through a combination of jet pumping and gas assisted lifting. A jet pump is located in a borehole in a producing zone of a well, and a source of gas is introduced into the fluid returning from the production location. The gas may be injected into the fluid used to operate the jet pump, such that the gas remains compressed until exiting the jet pump, and then provides assistance in lifting the returning fluid.

  • Patent number: 7066247
    Abstract: The present invention generally relates to an apparatus and method for removing hydrocarbons and other material from a wellbore. In one aspect, a method of drilling a sub-sea wellbore is provided. The method includes circulating a drilling fluid through a drill string from a surface of the sea to a drill bit in the wellbore. The method further includes pumping the fluid and drill cuttings from the sea floor to the surface with a multiphase pump having at least two plungers operating in a predetermined phase relationship. In another aspect, a fluid separator system having a first and a second plunger assembly is provided. The fluid separator system includes at least one fluid line for removing a fluid portion from the at least one plunger assembly and at least one gas line for removing gas from the first and a second plunger assembly.

  • Patent number: 6354318
    Abstract: A method and device for transferring a multiphase flow to a predetermined location through a pipe. The multiphase flow is comprised of at least a liquid phase and a gas phase. The multiphase flow is provided to a flow divider that diverts a gas portion from the multiphase flow. A compressor and a pump are in fluid communication with the flow divider. The main gas portion is boosted by the compressor, and the residual liquid/gas portion is boosted by the pump. A recombination manifold then recombines the gas portion and the residual liquid portion. A single pipe receives the recombined multiphase flow and transfers it to a predetermined location.

  • Patent number: 6234030
    Abstract: The present invention includes a method for multiphase metering of multiphase flow. the method begins with reducing gas volume to about 20% or less, then pumping the flow stream through two meters, a cut meter and a mass flow meter, arranged in series. Computations may be made on the flow stream to determine net oil rate, water cut, and gas fraction in the flow stream.

  • Patent number: 5252004
    Abstract: A "rod accumulator" riser tensioning cylinder assembly for use with off-shore production and exploratory drilling facilities. The tensioner is basically a hydro-pneumatic spring having a tubular cylinder equipped with a hollow rod containing sufficient volume to act as an accumulator. The rod is internally ported to the annulus of the cylinder. The cylinder exterior is coated with a material that will insulate the unit when exposed to high temperature and flame. A wear sleeve is supplied over the insulation material to provide a low friction surface for an outer, cylindrically shaped rod insulation jacket to slide over the cylinder when the rod is stroked into the cylinder. When the rod is stroked out, the jacket is also extended, protecting the rod from flame and high temperature due to its insulative properties. This is a low mass and low volume system, with low lateral area so that an increased number of such cylinder assemblies can be provided in a given horizontal area.

  • Patent number: 5169265
    Abstract: A fire protection system comprising a plurality of insulation protective jackets placed around the top joint of a riser string above and below the tensioner ring and its protective cover and over the threads or annular protrusions used to facilitate the connection of the tensioner ring to the top joint. Each protective jacket comprises an outer section of multiple layers of cloth, the outer layer being of an abrasive resistant, weather resistant material, and at least one of these layers being a woven ceramic fiber that helps to eliminate flame impingement, one or more layers of reinforcement (as many as required) and an inner section composed of a thick interior multi-layered composite layer of ceramic fibrous material and barrier films and an inner abrasion resistant liner to minimize heat transfer and gas passage to the protective part.
