Modeling of the Tbilisi (Georgia) Geothermal Deposit Under Climate Change Conditions
Georgia is rich with natural thermal waters and has a long tradition of their exploitation. Approximately 250 thermal springs and artificial wells are known, as well as spring clusters with water temperatures between 30°C and 108°C. The majority of these thermal water deposits have decreased well pressures due to irrational exploitation and climate change effects. In some cases, the complete termination of outflow has been observed. Based on the number of observed resources and their thermal potential, exploitation of thermal water deposits in the Tbilisi region is the most promising; thus, the assessment of its conditions are regarded as an important national priority. This paper summarizes the geothermal potential of the Tbilisi region based on development and application of a coupled 3D groundwater model using existing and newly obtained geologic, hydrogeologic, and geophysical data. Our modeling work resulted in a 10 year exploitation perspective of Tbilisi thermal deposits.
Abstract International collaboration is one mechanism to speed the development of carbon capture and storage. Support to investigate storage options for a coal-fired plant in the Chongqing Municipality was provided through a program funded by the World Bank. Geologic storage in saline reservoirs appears technically feasible based on the available evidence. The plant is located within a tectonically stable area of the Sichuan Basin, with low seismic activity and adequate capacity. However, multiple injection wells may be required, and the location of a fault near the plant merits additional distance for candidate sites. This study and guidance on future phases was augmented with capacity-building workshops in China and visits by the Chinese delegation to active carbon capture and storage sites outside of China.
