Patent number: 9347807Abstract: A system for determining densities and proportions of phases in a multi-phase fluid flow (MFF) that can include an oil phase, a water phase, and a gas phase from a well. The system includes a first density sensor that senses the MFF at locations where the phases of the MFF are often separated, a second density sensor senses the MFF from the output of a phase mixer-homogenizer, and a third density sensor that senses, in real time, the MFF where the gas phase starts to separate or has separated from the liquid phase but where the liquid phases have not separated. The system also includes one or more processors for executing one or more programs to determine a density of the oil phase, a density of the water phase, a density of the gas phase, and proportions of phases including a water cut and a gas volume fraction based on readings from the first, second, and third density sensors.Type: GrantFiled: November 15, 2012Date of Patent: May 24, 2016Assignee: GENERAL ELECTRIC COMPANYInventors: Xiaolei Shirley Ao, Oleg Alexander Khrakovsky, Yue Ma, Shawn Li Doria, Jin Chang Xu

Publication number: 20150107371Abstract: A method and system for measuring characteristics of an acoustic signal traveling through a fluid in a pipe uses an ultrasonic transducer attached directly to the pipe. The transducer is disposed in a housing attached to an outside surface of a flange of the pipe. The transducer fires an acoustic signal and its characteristics are measured.Type: ApplicationFiled: October 18, 2013Publication date: April 23, 2015Applicant: General Electric CompanyInventor: Oleg Alexander Khrakovsky

Patent number: 7942068Abstract: In one embodiment, a multi-path ultrasonic flow meter for determining the flow rate of a fluid in a conduit is disclosed comprising at least two transducer pairs attached to the conduit at two chord locations, one greater than and one less than a mid-radius chord, wherein the composite ratio the two path velocities to the flow rate is substantially constant over the range of Reynolds numbers. In another embodiment, a method of determining the flow rate of a fluid in a conduit is disclosed comprising the steps of determining a composite velocity by determining a weighted average of a plurality of path velocities, determining a chord velocity ratio based on the path velocities, determining a profile correction factor based on the composite velocity and the chord velocity ratio, and determining the flow rate based on the composite velocity and the profile correction factor.Type: GrantFiled: March 11, 2009Date of Patent: May 17, 2011Assignee: GE Infrastructure Sensing, Inc.Inventors: Xiaolei Shirley Ao, Robert Caravana, Edward Randall Furlong, Oleg Alexander Khrakovsky, Benjamin Edward McDonald, Nicholas Joseph Mollo, Lydia Shen
