Exploration of geothermal activity using time series analysis of subsurface gases data from Bakreswar hot springs area, eastern India

Quantitative Approximation of Geothermal Potential of Bakreswar Geothermal Area in Eastern India

“…But, heat and He generated due to each series were utilized to calculate the amount of heat production at the said reservoir at a certain instant of time. However, He emanation at the study area shows stable activities for a longtime-interval (5 years), as established by [19]. Therefore, He generation is also stabilized for a long period, i.e., He generation due to every radioactive decay series Location of the study area Bakreswar in the map of India (modified after [19]).…”

“…The reservoir, which is nothing but a volume consisting of hot permeable rocks, is usually sandwiched by capping of impermeable rocks. And it is favourably connected to a recharge (surficial) area [18], from which geothermal fluids percolated to recharge the aquifer cyclically [18,19]. The circulating fluids, to which the heat is transferred from the reservoir, escape through fracture and features from the deep reservoir and manifest through geysers, fumaroles, hot springs, etc.…”

“…The circulating fluids, to which the heat is transferred from the reservoir, escape through fracture and features from the deep reservoir and manifest through geysers, fumaroles, hot springs, etc. [8,19]. Moreover, through diffusion and advection process, the radioactive inert gases (like 222 Rn & 220 Rn) including the stable and inert gases (such as He, Ar) are spontaneously migrating upward from the deep Earth to the superimposing atmosphere [20][21][22].…”

“…It is notable that geothermal energy sources are still overlooked in India for power generation even after the existence of a lot of potential resources, which are seen in twelve geothermal zones of the country [19]. However, several of them could be well utilized for the generation of power by means of developing geothermal power plants.…”
