In at least one example, the desired property is gas oil ratio. In another example, the desired property is gas brine ratio. In a further example, the series of correlation equations comprises the Batzle and Wang relations. In another example, the receiving comprises receiving a plurality of input signals representing a plurality of measured properties of a fluid downhole and the processing comprises processing the plurality of input signals using the correlation equation expressing the desired property in terms of the plurality of measured properties.

Abstract: A stepped reflector on the outside of a bottomhole assembly produces two reflections in response to excitation of a transducer. The velocity of the fluid in the borehole is estimated using the two reflections. Alternatively, a change in the gas content of the borehole fluid is estimated from changes in the electrical impedance of a transducer in contact with the borehole fluid.

Abstract: An apparatus is disclosed for controlling heat flow in a downhole tool using a thermal rectifier material. The thermal rectifier material is positioned between a heat source and a heat sink for reducing flow of heat returning from the heat sink to the heat source. That is, the thermal rectifier conceptually operates as a “thermal check valve” so that heat, which has flowed (or been pumped) out of a region, has difficulty returning to that region. Another embodiment of an apparatus is disclosed for controlling heat flow in a downhole tool, which includes a thermal rectifier material surrounding a liquid supply, wherein the thermal rectifier material allows more heat to flow through the thermal rectifier in a first direction away from the liquid supply than in a direction through the thermal rectifier material toward from the liquid supply. A method for controlling heat flow in a downhole tool using a thermal rectifier material is also disclosed.
