Abstract: An intelligent completion module comprises a flowmeter that uses one or more electromagnetic acoustic transducer (EMAT) sensors and a flow control valve. The flow rate and the speed of sound in the production fluid from a production zone is measured and used to make reservoir management decisions. The flowmeter comprises at least two EMAT rings, comprising one or more EMAT sensors in a circular distribution which can be used in propagation or pulse-echo modes. In a segregated flow regime, a single EMAT sensor in pulse-echo mode is used to measure holdups of fluid components.

Abstract: The invention provides a signal processor that receives a signal containing information about an acoustic signal that is generated by at least one acoustic transmitter, that travels through an aerated fluid in a container, and that is received by at least one acoustic receiver arranged in relation to the container, including inside the container; and determines the gas volume fraction of the aerated fluid based at least partly on the speed of sound measurement of the acoustic signal that travels through the aerated fluid in the container. The signal processor also sends an output signal containing information about the gas volume fraction of the aerated fluid. The signal processor may be configured together with at least one acoustic transmitter, the at least one acoustic receiver, or both.

Abstract: A multiphase flowmeter for detection of fluid flow by monitoring of vortex frequency or perturbation time of flight. The flowmeter includes a bluff body to facilitate formation of vortices during a consistent phase of a flowing fluid. Thus, monitoring frequency of the vortices may be employed to ascertain flowrate. Further, the bluff body may also facilitate formation of perturbations during transitioning phase of the fluid and include perturbation sensors at multiple known locations along the flow-path. Thus, analysis of perturbation detection times at the different locations may be used to ascertain flowrate even in the absence of vortices.

Abstract: Apparatuses, systems, and methods are provided for measuring the velocity and direction of a fluid flow. In some instances, a measuring system may include a housing capable of holding one or more pressure sensors in a desired location and orientation. The housing may include a cavity for each of the one or more pressure sensors and each cavity may have a connection to an opening at the outside surface of housing. Each opening may be able to face in any desired direction such that the pressure at any desired location on the outside surface of housing, which may be capable of facing in any desired direction, may extend to the cavity inside housing where it can be measured by a pressure sensor. The velocity and the direction of a fluid flow around the housing of the measurement system may be based on pressure readings generated by the pressure sensors.
