Abstract

Numerical simulations of the Ogiri geothermal reservoir were conducted using a fractured reservoir model with particular focus on the periods of power plant maintenance when all production and reinjection wells are shut-in for a few weeks. The results show that the steam-water two-phase zone in the shallow reservoir shrinks somewhat and the single-phase water zone expands.
