With the advent of distributed temperature sensing (DTS), accurate andcontinuous monitoring of the wellbore-temperature profile is possible, whichhelps identify fluid flow from each reservoir layer. The reliable prediction offluid flow during large drawdown requires an accurate value of theJoule-Thomson coefficient (JTC), which is a measure of the change intemperature (T) of a fluid for a given change in pressure (P) atconstant enthalpy. The JTC also serves as an input for the interpretation oftemperature-log data, which can be used to identify water- or gas-entrylocations. Furthermore, an accurate JTC value is important when modeling thethermal response of the reservoir.
The equation-of-state (EOS) method can be used to predict the JTC ofreservoir gas. However, this might not be an easy task because of thecomplexity involved. In contrast, a simple and reliable method to evaluate theJTC for reservoir gas is presented. Conditions under which this method isapplicable are discussed in detail by referring to a typical phase diagram. Inaddition, a discretized approach to calculate the temperature change during athrottling process with the JTC is also presented.
The methodology has been validated at three levels with experimental dataavailable in the literature--comparison of experimental vs. predicted JTCvalues of mixtures, comparison of experimentally observed vs. predictedtemperature drop for a given pressure drop with laboratory-scale data, andcomparison of experimentally observed vs. predicted temperature drop for agiven drawdown with actual reservoir data. A good match with experimental datawas obtained within all three areas, demonstrating the reliability of themethodology.
