Reaction and Transport of Chemicals in a Two Phase Geothermal Reservoir

Abstract

Friedly (1991) and Friedly and (1992) developed a theory that described the transport of reacting chemicals in a porous media. This theory is limited to the isothermal transport of chemical species in the liquid phase but includes the possibility of precipitation of solids. Lichtner (1992) has considered simulation of interactions but also limits his consideration to the liquid phase. This work was extended by White (1994) by including the possibility of transport and reaction in the gas phase and by coupling the conservation equations for mass and energy transport to those for chemical species conservation. In this paper we outline this extension and then apply the method to several example problems.
