Hydrogeochemical and Isotopic Evidence for Seawater Contribution to Geothermal Waters in Mesozoic Granites of Eastern China

Energies
The geothermal system in the Jiaodong Peninsula is situated within a continent–ocean transition zone, where complex interactions among meteoric water, geothermal fluids, and seawater produce diverse hydrogeochemical and isotopic signatures, complicating ...

Magnetotelluric studies in Mongolia: Progress status and outlook

Mongolian Geoscientist
Mongolia is a unique natural laboratory for studying intracontinental surface deformation and intraplate volcanism due to its location within the high plateaus of the Central Asian Orogenic Belt, far away from active plate margins.

Geothermal Reservoir Characterization for Steam Field Management in Kamojang Geothermal Field-West Java

Atom Indonesia, 2011
Kamojang is the first geothermal field in Indonesia with a vapor dominated system reservoir. Kamojang has been exploited for over 20 years producing about 1100 tons/hour of steam which is equivalent to 140 Mwe electricity energy. This research is aimed to study the reservoir character after 20 years of exploitation and to investigate the effect of ...
