A TEMPERATURE DROP MODEL FOR TWO-PHASE FLOW IN GEOTHERMAL WELLBORES
This temperature-drop model is formulated as an answer to the question, ''How much further up the wellbore will a unit mass of fluid be when its temperature is exactly one-degree cooler than at its current position''. The repeated calculation yields a temperature profile extending upwardly from the bubble point. This approach is based on a paradigm that emphasizes temperature and volume for a system that is dominated by one component. It has only a small overlap with the more popular paradigm for this topic which involves mechanical pressures and energy balances. A set of plots is given which shows the effects on temperature and pressure profiles due to changes of single factors when all other factors are held constant. The factors include common wellbore and reservoir parameters. These latter plots give considerable insight into wellbore processes and the nature of constraints on two-phase flow for an essentially one-component substance.
