Zh. Duan et al., PREDICTION OF BOILING, SCALING AND FORMATION CONDITIONS IN GEOTHERMAL-RESERVOIRS USING COMPUTER-PROGRAMS TEQUIL AND GEOFLUIDS, Geothermics, 25(6), 1996, pp. 663-678
Predictions of boiling, scaling, and solubility of gases are important
to the exploitation of geothermal resources. These chemical phenomena
are strong functions of the composition, temperature and pressure of
the working fluid and are therefore difficult to predict from prior ex
perience or tabulated data. Thermodynamic models of geothermal brine b
ehavior recently developed by the authors are introduced and used to s
tudy various problems involved in geothermal energy production. The mo
dels have been extensively tested. Results of comparisons with laborat
ory measurements indicate that predictions are very close to experimen
tal data for a wide range of conditions. Comparisons with field data a
lso show remarkable agreement. Here the models are also applied to the
prediction of breakout and scale formation in geothermal wells. Good
agreement is obtained with actual well performance. Copyright (C) 1996
