Charles TOUSSAINT has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11994018
    Abstract: Geothermal production monitoring systems and related methods are disclosed herein. An example system includes a production well, an injection well, a downhole pump or a downhole compressor to control a production of a multiphase fluid including steam from the production well, a first fluid conduit to transport the multiphase fluid away from the production well, a surface pump disposed downstream of the first fluid conduit, and a second fluid conduit. The surface pump is to inject water into the injection well via the second fluid conduit. A flowmeter is fluidly coupled to the first fluid conduit. The example system includes a processor to control at least one of (a) the downhole pump or the downhole compressor or (b) the surface pump in response to fluid property data generated by the first flowmeter.

  • Patent number: 11230914
    Abstract: Systems and methods are provided for estimating and/or using drilling efficiency parameters of a drilling operation. A method for estimating drilling efficiency parameters may include using a borehole assembly that includes a drill bit to drill into a geological formation. A number of measurements of weight-on-bit and torque-on-bit may be obtained during a period in which weight-on-bit and torque-on-bit are non-steady-state. The measurements of weight-on-bit and torque-on-bit may be used to estimate one or more drilling efficiency parameters relating to the drilling of the geological formation during the period.

  • Patent number: 11150203
    Abstract: 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.
