    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 technique facilitates verification of the integrity of a lower completion prior to deployment of a corresponding upper completion. A lower completion is initially deployed downhole into a wellbore and comprises a plurality of functional components, such as a sensor, a communication system, a flow control system, and/or other functional components. A service tool system is removably deployed into the wellbore and comprises a service tool with an interface which interacts with the lower completion. The interface enables verification of the integrity, e.g. functionality, of various functional components of the lower completion without the use of an additional communication line, e.g. power cable, routed separately to the lower completion.
