| Abstract | Numerical studies of tracer test in vapor-dominated geothermal reservoir are conducted using two-dimensional cross sectional model. To investigate the flow path of the injected water, we used alcohols (methanol, ethanol, propanol, and butanol) as two-phase tracers. A pair of production-injection well scheme is used. TMVOC module of TOUGH2 simulator is used to simulate alcohol movement in the model. Sensitivity studies on parameters such as permeability and porosity are conducted over the range of reasonable value applicable to the vapor-dominated geothermal reservoir. Varying injection location is also conducted to observe injected fluid movement toward the production well. |
