Mikha is a PhD candidate and a geothermal geochemist specialising in non-condensable gas reinjection, using field data, experiments, and modelling to improve reservoir performance and storage efficiency. He has professional experience as a geochemist and wellsite geologist, and has worked in several geothermal fields in Indonesia, most recently as a geochemist for the Salak geothermal field. Mikha's PhD research focuses on developing reactive transport models for non-condensable gas (NCG) reinjection in geothermal systems with controlled mineralisation.
