[7][8] The Mahakam Bloc, the original INPEX's first site, was nationalized by the Government of Indonesia in 2018, and is currently operated by Pertamina.

[12] The main focus of the company's operations in Japan is the Minami-Nagaoka Gas Field in Niigata Prefecture.

This was for a previously wholly owned INPEX project in the offshore Basin off the north west coast of Western Australia where a gas-field was discovered in the WA-285-P permit area.

Environmentalists and local ecotourism operators ware concerned about industrial infrastructure destroying the pristine nature of this coast line.

INPEX said it and French energy company Total, its joint venture partner, had given the final approval to the project.

The project was estimated to contribute $3.5 billion into the Australian economy each year, and require around 2,700 workers during peak construction, and another 300 jobs ongoing once it is operational.

In November 2008, INPEX acquired a 100 per cent participating interest in the Masela Block in Indonesia.

[20] In 2017 the company was ready to start the Pre FEED phase and hold a joint workshop with SKK Migas.

[21] INPEX is a minority shareholder in the Kashagan Field in Kazakhstan and the Azeri-Chirag-Guneshli project, offshore Azerbaijan in the Caspian Sea.
