The use of modeling in drawing up guidelines for the exploitation of the Khankala geothermal field (Chechen Republic)
Résumé
Nowadays, geothermal waters have become an important form of energy and many
researchers have put to the forefront the issue of “sustainability” of the geothermal
reservoir development. Reinjection of the used fluid during exploitation allows
minimizing the possible negative effect on the environment and maintaining the
reservoir pressure and therefore the initial high flow rates. However, it has a major
disadvantage—a gradual temperature decrease in an aquifer, which needs to be taken
into account. The most effective methods assessing this disadvantage are based on
numerical modeling, which has been actively implemented in all areas of science. In
the current paper, mathematical modeling is applied for the Khankala geothermal
field in the Chechen Republic to forecast changes in the temperature regime of the
resource and define the optimal exploitation scenario to achieve its sustainable
development.
