Commencement of CO2 Injection Field Test at Sukowati Oil Field in Indonesia


Japan Petroleum Exploration Co., Ltd. (hereinafter ‘JAPEX’), PT Pertamina (Persero), the national energy company of Indonesia (hereinafter ‘Pertamina‘), PT Pertamina EP (hereinafter ‘PEP’), and Japan Organization for Metals and Energy Security (hereinafter ‘JOGMEC’) have started CO2 injection field test (hereinafter ‘the field test’) at the Sukowati oil field in East Java Province of Republic of Indonesia (hereinafter ‘Indonesia‘) on December 7, 2023.

The field test is based on the Joint Study Agreement signed this July (1) with Pertamina, PEP, and JOGMEC to conduct CO2 injection using the Huff & Puff method (2) into the Sukowati oil field to help verify the CO2-EOR (Enhanced Oil Recovery) and the CO2 sequestration effect.

This is the first CO2 injection into an oil and gas field in Indonesia for JAPEX and will be an essential step toward the commercialization of carbon neutral fields such as CCS (Carbon dioxide Capture and Storage) / CCUS (Carbon dioxide Capture, Utilization, and Storage) in the country.

In ‘JAPEX2050’, formulated to realize a carbon-neutral society, we set the commercialization of fields that contribute to achieving net zero emissions, centered on CO2 injection and storage technologies, as one of the focused efforts. Including the field test, we aim to grow as a comprehensive energy company supplying various energies needed as times change and increase our corporate value through solving issues and realizing businesses for carbon neutrality in Japan and overseas.
