    摘要: Virtual and non-invasive multiphase metering is performed for recognition of multiphase flow regimes of hydrocarbons and other fluids, flow rate, presence of sand, and other multiphase flow parameters. A passive acoustical detector system receives acoustical flow information in the form of acoustic emission signals, and a data processor processes and classifies the acoustical patterns. A statistical signal processing methodology is used. Acoustic models are provided for various flow regimes and flow patterns, using Artificial Intelligence methods including Hidden Markov Models and Artificial Neural Networks along with automated learning procedures. The metering can be used for downhole, top side and surface applications.

    摘要: A method of using an electrochemical gas lift apparatus to induce artificial gas lift in a production fluid includes introducing the electrochemical gas lift apparatus into a well bore having a production zone, operating the electrochemical gas lift apparatus such that a combination of hydrocarbon fluid and formation water is introduced into the interior of the electrochemical gas lift apparatus, introducing electrical power to the electrochemical gas lift apparatus such that at least a portion of formation water in the interior of the electrochemical gas lift apparatus converts into product gases, operating the electrochemical gas lift apparatus such that the product gases form product gas bubbles in the interior of the electrochemical gas lift apparatus, and operating the electrochemical gas lift apparatus such that production fluid forms in the interior of the electrochemical gas lift apparatus. The production fluid comprises hydrocarbon fluid, unconverted formation water and product gas bubbles.

    摘要: An artificial lift device is useful for inducing artificial gas lift in a well bore fluid present in a horizontal well bore system using electrically conductive aqueous solution. The artificial lift device includes an ion exchange membrane, an electrode pair having an anode and a cathode separated by the ion exchange membrane, a sensor operable to detect the presence of solution and a power relay operable to selectively permit the electrode pair to receive electrical power. The artificial lift device is operable to form hydrogen product gas bubbles from hydrogen product gas. A method for providing artificial gas lift using the artificial lift device includes forming a horizontal well bore system having a well boot, introducing the artificial lift device into the well bore system, introducing electrical power to the electrode pair, and operating the device to introduce hydrogen product gas bubbles into the horizontal well bore system.

    摘要: An apparatus for controlling fluid pressure, useful in the production of hydrocarbons from underground reservoirs comprises at least one conical segment. A conical segment comprises: an inner conical cylinder with a central axis; an outer conical cylinder, outside of, and coaxial with, the inner conical cylinder; and a swirl chamber disposed between a conical outer surface of the inner conical cylinder and a conical inner surface of the outer conical cylinder. There is a fluid entrance through a wall of the outer conical cylinder of at least one conical segment at an upstream end of the apparatus for directing fluids into such conical segment's swirl chamber. There is also a fluid exit through a wall of the inner conical cylinder of at least one conical segment at a downstream end of the apparatus for directing fluids out of such conical segment's swirl chamber.
