Japan Oil, Gas and Metals National Corporation (JOGMEC) has embarked on its first overseas geothermal research project in partnership with PT Geo Dipa Energi (GDE), marking a significant milestone in its geothermal business activities.
The initiative is being undertaken as part of two Japanese government-led programs: the Asia Zero Emissions Community (AZEC) initiative and the Asia Energy Transition Initiative (AETI).
Indonesia, which holds the world’s second-largest geothermal resource potential, has become a prime destination for investment by Japanese companies seeking opportunities in geothermal resource development.
JOGMEC and GDE have been working toward this collaboration since 1 March, 2023, when the two parties signed a Memorandum of Understanding (MoU) aimed at establishing a cooperative relationship in geothermal development. As a result of ongoing efforts, they have now formalised and commenced the joint research agreement.
“Acidic fluids cause corrosion in wells and piping equipment. If the spatial distribution of acidic fluids can be accurately identified and neutral fluids can be selectively collected, it will contribute to the long-term stable operation of geothermal power plants.”
This research will apply JOGMEC’s risk evaluation methodology for acidic fluids to large-scale geothermal fields in Indonesia. The fields will serve as test sites for further advancing the technique through detailed technical evaluation. In addition to supporting GDE’s ongoing research and exploration in its operational areas, the project is also expected to benefit geothermal resource development in Japan.
“JOGMEC and GDE will continue to cooperate in geothermal resource development to achieve energy transition, which is important for both countries to simultaneously promote stable energy supplies, sustainable economic growth, and climate change measures.”
This joint research underscores the deepening cooperation between Japan and Indonesia in sustainable energy and represents a step forward in regional energy transition and environmental resilience.
