Technologies for Geoinformation Modeling of Spatial Distribution of Geothermal Resources

The paper deals with the technologies of geoinformation modeling of potential geothermal resources and technically accessible geothermal resources distribution on the example of Dagestan.
One of the tasks that precedes the development of potential heat of dry rocks is the task of obtaining information on the spatial distribution of geothermal resources. The solution of this problem allows: to identify the territories that have the greatest geothermal potential, to compare these territories with the objects of infrastructure, as well as with maps of the potential of wind and solar energy for possible combined use. This information is very important when choosing the optimal areas for the construction of geothermal energy facilities.
The task of obtaining information on the spatial distribution of geothermal resources is complex and has a number of sub-tasks, such as the construction of a geological model and a model of the temperature field of the region, so its solution is possible with the use of specialized geoinformation technologies. In these geoinformation technologies lies the concept of constructing a system of three-dimensional geoinformation modeling (STGM).
A three-dimensional geoinformation model of the territory of Dagestan was created in STMG. Within the framework of the project, three-dimensional geological model and a three-dimensional model of the temperature field were constructed, which formed the basis for the construction of cartographic models for the distribution of potential geothermal resources and technically accessible geothermal resources.
As a result of geoinformation modeling, the regions of Dagestan are identified, which are the most promising from the point of view of the technical potential of using geothermal energy in the communal sector. For hot water supply are promising areas of Central Dagestan, the neighborhoods of settlements: Kizilyurt, Shamkhal, Sulak, Khasavyurt and Kizlyar. For heating perspective: the whole area of Piedmont Dagestan from north to south and the northern part of the republic, starting from the settlement of Kizlyar.
