    Abstract: Described is an apparatus for gas identification using a re-entrant microwave cavity. The re-entrant microwave cavity includes a tubular body having an exterior wall, a top portion, and a bottom portion. An inner conductor is positioned within the tubular body. A measurement conduit is positioned within the central conductor and extends from the bottom portion to the top portion of the tubular body. A cavity entry in connection with a first end of the measurement conduit is formed proximate the bottom portion of the tubular body to receive one or more gases from below the tubular body. A cavity exit in connection with a second end of the measurement conduit is formed proximate the top portion of the tubular body to release the one or more gases from the tubular body. A high frequency connector is configured to connect the tubular body to a microwave source.

    Abstract: A system includes a housing configured to be secured to the casing string. The housing has a ring shape defining a central orifice for passage of the fluid and an interior surface facing the central orifice. A reflectometer is mounted on the interior surface and is configured to emit a microwave signal into the fluid in the central orifice, receive a reflected microwave signal from the central orifice, and determine a microwave reflection parameter. An acoustic transceiver is also mounted on the interior surface and is configured to emit an acoustic signal into the fluid in the central orifice, receive a reflected acoustic signal from the central orifice, and determine an acoustic reflection parameter. A processor is configured to determine the property of the fluid from the microwave reflection parameter and the acoustic reflection parameter.
