  • 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: 11591906
    Abstract: A cutting tool with a cutting region and a connecting support region where the support region is designed to connect to an external motor assembly. The cutting tool is also has a porous region that is integrated within a portion of the tool such that as the tool cuts material the porous region can allow samples of the cut material to permeate into an internal chamber of the tool. Once in the internal chamber material samples can be analyzed in-situ for direct composition analysis.

  • Publication number: 20220075378
    Abstract: Systems and methods for visual inspection of a container such as an oil tank via a lighter-than-air aircraft are presented. According to one aspect, the aircraft includes a gondola attached to a balloon filled with lighter-than-air gas. Rigidly attached to the gondola is a suite of sensors, including a camera sensor, an inertial measurement unit and a range sensor. Navigation of the aircraft is based on information sensed by the suite of sensors and processed by control electronics arranged in the gondola. Embedded in the control electronics is an extended Kalman filter that calculates pose estimates of the aircraft based on the information sensed by the inertial measurement unit and updated by the camera sensor. The extended Kalman filter uses the information sensed by the range sensor to reduce uncertainty in the calculated pose estimate. Images captured by the camera sensor can be used to evaluate state of the container.
