| Abstract | Numerical simulations of the Ogiri geothermal field were conducted using a fractured model for evaluating reinjected water return to production wells. A MINC method was applied to grid blocks both in production and reinjection zones for describing a quick return of reinjected water in reservoir. A mixing ratio of reinjected water to the produced fluid at respective production wells were quantitatively evaluated by using a function of two kinds of waters built in the TOUGH2 numerical simulator. |
