  • Publication number: 20240229643
    Abstract: Systems and methods for measuring multiphase flow of a fluid mixture in a downhole pipe of an oil/gas/water well are presented. According to one aspect, time-series measurement of the flow velocity and composition at a plurality of discrete azimuths of the pipe are measured. Measured time-correlated velocity and composition data are used to identify fluid components present in the pipe and estimate cross-sectional area and velocity of each of the fluid components. According to another aspect, pressure and temperature at the downhole pipe are measured, and used to calculate the mass density of each fluid component. For each of the fluid components, the cross-sectional area, velocity, and mass density are used to generate a corresponding mass flow rate. An algorithm with a set of parameters tuned to specific flow regimes is used to map the sensed data from the time-scrics measurements into the mass flow rate of each fluid component.

  • Publication number: 20240125636
    Abstract: Systems and methods for measuring flow velocity of a fluid mixture in a lateral section of an oil/gas/water well with a dual beam laser doppler velocimetry (LVD) based flow sensor are presented. According to one aspect, the flow velocity is measured by tracking movement of particles and/or features in the fluid mixture while traversing an interference pattern generated by the intersection of two separate coherent beams that are perpendicular to a direction of the flow. Flow velocity is derived based on a time it takes the particles to traverse consecutive fringes of the interference pattern as indicated by intensity peaks detected at the photodetector. The LDV-based flow sensor may be rotatable to measure flow velocities at different angular positions of a pipe in a lateral section of an oil well, rotation provided by rotation of an element of a mobile vessel to which the flow sensor is rigidly coupled.

  • Patent number: 9810060
    Abstract: A formation tester for use in a subterranean well can include a probe which extends outward into contact with an earth formation, and an adjustable flow control device which limits an extension pressure applied to extend the probe. A method of testing a subterranean formation can include positioning a formation tester in a wellbore, extending a probe of the formation tester outward into contact with the formation, and limiting a force applied by the probe to the formation, the limiting being performed by variable actuation of a flow control device downhole. Another formation tester can include a probe which extends outward into contact with an earth formation, with a force applied by the probe to the formation being remotely adjustable downhole.

  • Publication number: 20150240586
    Abstract: A sealing system can include an annular seal comprising a resilient material, and a spring which applies a compressive force to the seal as a resilience of the material diminishes, the spring being external to the seal. A sealing method can include installing a seal in a well tool, the seal being compressed radially as a result of the installing, and a spring external to the seal exerting a compressive force on the seal. A well tool can include a seal radially compressed between seal surfaces of the well tool, due to the seal having a greater radial dimension as compared to a radial distance between the seal surfaces, and a spring which exerts a compressive force on the seal, the spring being external to the seal.
