Patent number: 10370959Abstract: A flow rate sensing system can include an optical waveguide, an optical interrogator that detects optical scatter in the optical waveguide, and an emitter that produces vibration in response to flow, the optical scatter being influenced by the vibration. A method of measuring flow rate can include detecting optical scattering in an optical waveguide, the optical scattering varying in response to changes in vibration produced by an emitter, and the vibration changing in response to the flow rate changing. A well system can include at least one tubular string positioned in a wellbore, multiple locations at which fluid flows between an interior and an exterior of the tubular string, multiple emitters, each of which produces vibration in response to the flow between the interior and the exterior of the tubular string, and an optical waveguide in which optical scatter varies in response to changes in the vibration.Type: GrantFiled: August 20, 2014Date of Patent: August 6, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Mikko Jaaskelainen, Priyesh Ranjan, Nitika Kalia

Patent number: 10365136Abstract: An opto-acoustic flowmeter can include an optical waveguide and an emitter that emits acoustic energy in response to flow, the acoustic energy comprising a flow rate dependent parameter. A flow rate measuring method can include configuring an emitter so that flow into or out of a tubular string causes the emitter to emit acoustic energy, arranging an optical line so that the acoustic energy is received by an optical waveguide of the optical line, and detecting optical scatter in the optical waveguide. A well system can include multiple locations where fluid is flowed between an earth formation and a tubular string in a wellbore, multiple emitters that produce an acoustic vibration corresponding to a flow rate of the fluid, an optical line that receives the vibrations, and an optical interrogator that detects optical scatter in an optical waveguide of the line, the scatter being indicative of the vibrations.Type: GrantFiled: August 20, 2014Date of Patent: July 30, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Mikko Jaaskelainen, Priyesh Ranjan, Nitika Kalia
