Abstract
Many geothermal reservoirs contain no steam(liquid Numerical models of systems of this typemay taking advantage ofthe using theNIGHTS simulator. NIGHTS the approximation: the fluid density is regarded independent of pressurc. depends composition. convection problems (freeand forced),and incorporates anonequilibrium thermal model for fractured systems. The simulator is routinely used for modeling the natural state of liquid-dominated hydrothermal reservoirs and also for calculating rcsponsc fluid operations in which the reservoir remains despite production-induced pressure decline.
