Multiphase flowmeters and related methods are disclosed herein. An example multiphase flowmeter includes a microwave transmitter to transmit a signal through a fluid, a microwave receiver to determine at least one of attenuation or phase shift, a sensor to obtain at least one of pressure, temperature, or differential pressure, an intermediate-output generator to determine intermediate flow parameters, and a flow rate generator to determine a flow rate for respective phases in the fluid, and a model selector to select at least one of a physics model or a machine learning model for determining the intermediate flow parameters or the flow rates, the physics model to determine a first value of the intermediate flow parameters or the flow rates, and, in response to an error not being less than a threshold, the machine learning model to determine a second value of the intermediate flow parameters or the flow rates.

Multiphase flowmeter and related methods

Electromagnetic probes for analyzing a flowing multi-phase fluid are described herein. The probes generally use a probe assembly for measuring liquid properties in a multiphase fluid flowing in a conduit, the probe assembly comprising a first member with a probe portion and a connection portion, the probe portion having a central bore with a conductor and a pressure-resistant insulator surrounding the conductor, the conductor extending from an opening at a distal end of the probe portion into the connection portion, the connection portion having a connector coupled to a distal end of the connection portion, the connection portion having a seal face with a groove extending around the probe portion; and a second member that, when assembled, is in direct contact with the first member at the distal end of the connection portion to apply compression and to retain the first member against a wall of the conduit.

A method for analyzing flow of a multiphase fluid through a flowmeter is provided. In one embodiment, the method includes transmitting two beams of electromagnetic radiation along different paths through a multiphase fluid and detecting the two transmitted beams with detectors. The method also includes determining a gas fraction and a water-in-liquid ratio of the multiphase fluid. The gas fraction is determined based on the detected first beam of electromagnetic radiation and the water-in-liquid ratio of the multiphase fluid is determined based on the detected second beam of electromagnetic radiation. Additional systems, devices, and methods are also disclosed.

Dual-beam multiphase fluid analysis systems and methods

A technique facilitates evaluation of a fluid, such as a fluid produced from a well. The technique utilizes a modular and mobile system for testing flows of fluid which may comprise mixtures of constituents, and for sampling fluids thereof. The multiphase sampling method includes flowing a multiphase fluid comprising an oil phase and a water phase through a first conduit, the oil phase and water phase at least partially separating in the first conduit, mixing together the oil phase and water phase to form a mixed bulk liquid phase by flowing the multiphase fluid through a flow mixer toward a second conduit downstream the flow mixer, sampling a portion of the mixed bulk liquid phase at location at or within the second conduit, wherein the sampled portion of the mixed bulk liquid phase has a water-to-liquid ratio (WLR) representative of the pre-mixed oil phase and water phase.
