Abstract: Cooling of downhole components is effected using an expendable refrigerant, such as water. Refrigerant, in thermal communication with a component to be cooled, is evaporated in an evaporator. Vapor is removed from the evaporator and released into a borehole, in order to cool the component. A pump may be used to remove the vapor from the evaporator and force the vapor into the borehole.

Abstract: A method of measuring multiphase flow of components in a wellbore fluid mixture by selectively heating components (e.g. oil and water) in the flow with electromagnetic energy, and detecting the heated components at a known distance downstream. The flow and velocity of components in the flow stream can be estimated with the present method. Example types of electromagnetic waves include infrared, microwaves, and radio waves. The different components can be heated simultaneously or at different times. The heated components can be detected with one or more temperature probes, and oil wet or water wet probes can be used to improve thermal contact to the corresponding components in the fluid stream.
