Modeling Supercritical Systems With Tough2- The Eoslsc Equation Of State Module And A Basin And Range Example
Conference Paper: Modeling Supercritical Systems With Tough2- The Eoslsc Equation Of State Module And A Basin And Range Example
AbstractA supercritical fluid equation of state module (EOSlsc) has been developed for use with the TOUGH2 geothermal reservoir simulator. Supercritical fluid conditions (D374"C) have been observed at depth in magmatic geothermal systems and are important in the deep heating zones of extensional geothermal systems as well. As interest in the sustainability of mature geothermal fields increases, and as exploration for high temperature resources becomes more attractive, the ability to model an entire field from ground surface to supercritical regions will become crucial. Tests using the EOSlsc module successfully reproduce sub-critical sample problem results of EOS 1. Supercritical validation suites are currently lacking, but preliminary models reasonably extend sub-critical model results to supercritical conditions. For example, generic models of extensional settings using EOSlsc with supercri tical temperatures at depth better-simulate observed temperature depth profiles (e.g. Dixie Valley, NV) than EOS 1 -based models.
