Modeling of Temperature Conditions of Reinjection in Geothermal Reservoirs

Abstract

A thermal simulator is presented that originally was developed to model multiphase fluid flow in hydrocarbon reservoirs. The model has a modular structure. The module, and the fluid module are highly independent parts of the model. The integrated finiteform is used. changing the fluid module (the multicomponent, multiphase hydrocarbon module) to a one component, steam--water system, the model can be used to simulate geothermal A new numerical solution technique is applied: the pressure and temperature distributions are calculated directly, without iterations from the mass and energy balance equations. No mass and energy balance errors occur. model used to decreasr rates of the Transdanubian spa, where the water supply is coming from temperature sources a other application simulated the pressure and temperamre distributions gcothermal field
