THERMOHYDRODYNAMIC MODELING OF THE NATURAL STATE OF THE MUTNOVSKY GEOTHERMAL RESERVOIR (KAMCHATKA)

Abstract

The paper presents results of modeling of the natural state of the Mutnovsky geothermal field (Kamchatka) developed to produce electric energy. The modeling was performed using the TOUGH2 program, currently the most perfect instrument for analyzing heat-and-mass transport in porous-fissured medium. It is based on the conceptual model of a geothermal reservoir based on previous investigations. The results confirmed the main statements of the conceptual model: location of heat sources, pattern of fluid flow in the reservoir, and location of the two-phase zone, and can serve as a basis for predicting the behavior of the Mutnovsky reservoir during its exploitation.
