The spatial distribution of pre-exploitation conditions (e.g. temperature and pressure distributions, liquid and vapor saturations, circulation characteristics of high-temperature fluids) in the Dachny site of the Mutnovsky hydrothermal system, obtained earlier using a 3-D mapping method (Kiryukhin et al, 1991), are revised on the basis of natural state simulations performed with the computer code TOUGH2 (Pruess, 1991). A 3-D model of the natural state conditions at the Dachny site was developed. The fine-tuning of the model has been achieved by comparing model results to the observations made in geothermal wells 1, 24, 01, 016 and 26 during flow tests conducted during 1983--1988. The behavior of these five wells in response to two exploitation scenarios, one with no reinjection, the other with 100 kg/s of liquid injection into well 027, was also computed.
