Conference Paper: Fluid Inclusion Studies At Tatapani Geothermal Field, District Surguja, Chhattisgarh, India

Abstract
Fluid inclusion studies, Th and Tm measurements were carried out on samples from Tatapani Geothermal Field, district Surguja. The Th may be categorized into 3 groups (a) >200"C, (b) 15O-20O0C, (c) ~150°CT.m ranges from -0.3 to -21SoC, and salinity varies from 0.5% to 23.3%, with an average of 8.9%. Most of the fluid inclusions are two phase suggesting boiling at depth. The correlation of fluid inclusion data with other geothermal indicators suggest that the system initially at 25OoC, which was cooled due to mixing with meteoric water. The mode of 190-200°C indicates a period of stabilized temperature in the reservoir. Shallow mixing generated low salinity low temperature fluid inclusions. Thus, though the shallow reservoir indicates temperature of 140- 15OoC, the reservoir at deeper level may have higher temperature.
