Heat extraction in fractured hydrothermal reservoirs: Final report
The main objective of the Heat Extraction Project has been the development of means to estimate the thermal behavior of geothermal fluids from fractured hydrothermal resources based on production of mixed reservoir fluids from heat sweep by reinjected brine and resource fluid cooled by drawdown and infiltrating waters. Several reports and publications, listed in the concluding section of this report, resulted from the application of the SGP heat sweep model to achieve this objective. The Heat Extraction Project made major advances in the development of the 1-D Heat Sweep Model and its application in geothermal fields in several countries. Heat sweep joint studies are underway for reinjection evaluation at the Los Azufres, Los Humeros, and La Primavera fields in Mexico, for the 500 t/h reinjection test for the redevelopment program at Wairakei, New Zealand, for two hot water supply recirculation systems to be developed in the USSR, and for the phase 2 test at the Hot Dry Rock project at Fenton Hill, New Mexico. Advances were also made in the cooperative studies with CFE at Los Azufres on the evaluation of the effects of early operation of small wellhead generators on the reservoirs of potentially large geothermal fields. 9 refs., 5 figs.
