Abstract: A logging tool for use downhole includes sensor modules that monitor fluid flow in a wellbore. The sensor modules are disposed on flexible arms that project radially outward from the logging tool, so that the modules are located at discrete radial positions in the wellbore. The sensor modules include a flow sensor, an optical sensor, and a fluid conductivity sensor. The rate and type of fluid flowing in the wellbore can be estimated due to employing the different sensor types. A location sensor estimates the radial location of the modules so that a flow profile of the flowing fluid can be obtained.

Abstract: An apparatus for performing a measurement of a downhole property includes an optical fiber having a first section that has a first set of fiber Bragg gratings with a first resonant wavelength inscribed therein and a second section that has a second set of fiber Bragg gratings with a second resonant wavelength different from the first resonant wavelength inscribed therein. The second section is in series with the first section. An optical interrogator emits a swept-wavelength frequency domain light signal having varying wavelength amplitude modulation into the optical fiber, receives a frequency domain return light signal, and transforms the frequency domain return signal into a time domain to determine a resonant wavelength shift of each fiber Bragg grating and the corresponding location of each interrogated fiber Bragg grating. A processor converts the resonant wavelength shift of each interrogated fiber Bragg grating into the downhole property measurement.
