A controller is coupled to the waveguide sensor and configured to perform a compression-wave acoustic measurement on the fluid using the acoustic waveguide sensor in order to estimate the fraction of each component of the fluid and to perform a shear-wave acoustic measurement in order to estimate the property of the fluid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three-phase flow identification and rate detection","description":"An apparatus for estimating a fraction of each component of a fluid of interest flowing in a cased borehole and a property of the fluid includes an acoustic waveguide sensor having a waveguide configu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9739904","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
