Abstract
Magnitude of return of reinjected water to production wells was evaluated by numerical simulations with TOUGH2 at the Ogiri geothermal field for 13 years operation. A function of specifying two kinds of fluid in TOUGH2 was used to distinguish reinjection water and deep recharge fluid. Production wells located relatively adjacent to reinjection zone showed high mass ratio of reinjected water to produced fluid.
