  For design calculations, use a linear temperature distribution from the reservoir temperature to the production wellhead temperature (not the injection gas surface temperature). Temperature surveys in this case indicate that the injection gas rapidly acquires the temperature of the production fluids in the annulus when the well is in normal operation (after unloading) so it would be a mistake to estimate the valve design temperature equal to the linear temperature distribution from the reservoir temperature to the surface gas injection temperature. For troubleshooting analyses, a temperature virtually equal to the production temperature in the annulus at valve's depth can be used because, as previously indicated, the injection gas can be considered to be at that temperature.
