Abstract: Methods for determining phase fractions of a downhole fluid via thermal properties of the fluids are provided. In one embodiment, a method includes measuring a temperature of a fluid flowing through a completion string downhole in a well and heating a resistive element of a thermal detector at a position along the completion string downhole in the well by applying power to the resistive element such that heat from the resistive element is transmitted to the fluid flowing by the position. The method also includes determining, via the thermal detector, a flow velocity of the fluid through the completion string and multiple thermal properties of the fluid, and using the determined flow velocity and the multiple thermal properties to determine phase fractions of the fluid. Additional systems, devices, and methods are also disclosed.

Abstract: A downhole sensor system includes a first sensor package having a substrate, an integrated circuit chip mounted to the substrate, the integrated circuit chip including a processor, a transducer chip mounted to the integrated circuit chip, and a plurality of sensors configured to measure at least shock, pressure, temperature, and humidity. At least one of the plurality of sensors is mounted to the transducer chip such that a stack is formed at least from the substrate, the integrated circuit, the transducer chip, and the sensor. The plurality of sensors are in communication with the processor.
