The Abadi LNG Project is based on an onshore LNG development scheme that INPEX as the operator is preparing for development alongside Shell in the Masela Block offshore Indonesia. The project is expected to produce approximately 9.5 million tons of LNG per year and up to approximately 35 thousand barrels of condensate per day. The project will also supply 150 million cubic feet of natural gas per day via pipeline to address local demand for natural gas. INPEX acquired a 100% interest in the Masela Block in November 1998 through an open bid conducted by the Indonesian authorities. INPEX subsequently conducted exploration activities as the operator, discovering the Abadi Gas Field through the first exploratory well drilled in 2000. Following exploration, evaluation activities and development studies, INPEX conducted Pre-FEED work from March to October 2018 based on an onshore LNG development scheme envisaging an annual LNG production capacity of 9.5 million tons. INPEX submitted a revised plan of development in June 2019 and received approval from the Indonesian authorities in July 2019. Alongside the approval of the revised development plan, the Indonesian authorities also approved an extension of the term of the Masela Block Production Sharing Contract (PSC) until 2055. Subsequently, detailed survey work in the planned construction site for the LNG plant and its surrounding areas was underway until it was suspended due to the impact of the COVID-19 pandemic. Considering the need to contribute to a net zero carbon society, INPEX is conducting a comprehensive study of measures such as the introduction of CCUS to make the project cleaner and further reduce costs and promote the project as a competitive and clean project with the aim of commencing production in the early 2030s.

MI Berau B.V., jointly established by INPEX and Mitsubishi Corporation, acquired an interest in the Berau Block in October 2001. In October 2007, MI Berau Japan Ltd., also a joint venture with Mitsubishi Corporation, acquired a stake in KG Berau Petroleum Ltd., effectively increasing INPEX’s interest in the Tangguh LNG Project to around 7.79%. In March 2005, Indonesian authorities approved an extension of the PSC and project development plans for the Tangguh LNG Project until 2035. Following development work, the first shipments of LNG began in July 2009. The final investment decision (FID) to expand the Tangguh LNG Project was made in July 2016. The Tangguh LNG expansion project will add a third LNG processing train, which is currently under construction, with production capacity of 3.8 million tons per annum, to the existing two trains with production capacity of 7.6 million tons per annum.

In 2004, INPEX acquired Blocks 05-1b and 05-1c, located 350 kilometers southeast of Ho Chi Minh City, Vietnam. In 2010, an exploration well was drilled in the Dai Nguyet (DN) structure leading to the discovery of gas and condensate accumulations. In 2014, another exploration well was drilled in the Sao Vang (SV) structure which also led to the discovery of gas and condensate accumulations. In 2017, a development plan for the SV/DN gas field was approved by the Vietnamese government, and sales of gas from the Sao Vang Gas Field commenced in November 2020. Development work will also continue on the Dai Nguyet Gas Field.
