A case study of the modeling of a hydrothermal reservoir: Khankala deposit of geothermal waters
Résumé
tIn 2013 the Grozny State Oil Technical University together with members of the “Geothermal resources”consortium started a pilot project to build a geothermal plant on the basis of the most promising XIIIlayer of the Khankala thermal waters deposit. Planned capacity of the projected facility is 22.8 GJ/h,which will heat a greenhouse complex. Geostatistical analysis and numerical simulations are requiredfor achieving sustainability in exploitation of the resource and in order to define new drilling sites. Inthis paper intrinsic random functions of k order kriging (IRF-k) is used for the XIII layer map creation andestimation of the temperature distribution within it. The results obtained by geostatistical approach areused for numerical simulation of the hydro-thermal process relied to reinjection of cold thermal waterback into the productive layer. The work carried out allows highlighting the most promising zones forexploitation and shows that the geothermal water temperature in the production well starts to decreaseafter 6 years.
