Abstract
We present a model of the rate at which water migrates under gravity through a vapour-saturated geothermal reservoir from an injection well. Our model accounts for the vaporisation of a fraction of the liquid as it is heated by the hot permeable rock. We show that injection from a central well at constant flux leads to a radial migration of liquid into the reservoir at a rate scaling as with the depth of the liquid layer decreasing with radius.
