As a result of a government-orchestrated merger, INPEX Corporation and Teikoku Oil agree to form INPEX Holdings on April 3, 2006. On October 1, 2008, the merger was completed with Inpex Corporation being formed from INPEX Holdings, INPEX, and Teikoku Oil, and the headquarters were moved to Akasaka, Tokyo. The Mahakam Bloc, the original INPEX's first site, was nationalized by the Government of Indonesia in 2018, and is currently operated byPertamina.
Teikoku Oil
Teikoku Oil Company Ltd was founded as a semi-governmental company to unify the existing Japanese oil exploration companies in 1941.

Projects
Operations in Japan
The main focus of the company's operations in Japan is the Minami-Nagaoka Gas Field in Niigata Prefecture.
Ichthys
INPEX created a venture company called INPEX Browse, Ltd on 1 September 1998. 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. The official name of the proposed development project will be the Ichthys Development, which the company wanted to base on the Maret Islands. After farming out 24% of the permit ownership to Total S.A.'s subsidiary Total E&P Australia the concept and location was changed. The location of this project, and the issue of industrialising the Kimberley coast is under discussion in Australia. Environmentalists and local ecotourism operators are concerned about industrial infrastructure destroying the pristine nature of this coast line. The original project consisted of an offshore Central Processing Facilities, supplying two phase gas to an onshore facility on the Maret Islands. The facilities on the Maret Islands were to include gas receiving, LNG process plant, product storage and export facilities. Maret Islands are located approximately 200 km south-east of the Ichthys Field, which is approx. 440 km north of Broome and 800 km south west of Darwin. The project for the LNG plant to be located on the isolated Maret Islands was scrapped with the LNG Plant now to be built at Blaydin Point industrial site which is located on the Middle Arm Peninsula in Darwin, Northern Territory, with a pipeline from the lchthys Field to the LNG Plant, after regulatory delays in Western Australia. The Ichthys Project's Front-End Engineering Design was completed in April 2011. Final Investment Decision was announced on 13 January 2012. In January 2012 Inpex said the 8.4 million tonne per annum project near Darwin will cost about $34 billion, some 60 per cent more than Inpex's original estimate of $20 billion. Inpex said it and French energy company Total, its joint venture partner, had given the final approval to the project. Total had expressed interest in increasing its stake in the project from 24% to 30%, and negotiations between the two companies were underway. The project will pump $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. The EPC early works phase, such as commencement of site development, infrastructure works and accommodation village and dredging began in 2012. LNG Production in the magnitude of app. 8.4mtpa is projected to be online by fourth quarter of 2016.
Abadi
In November 2008, INPEX acquired a 100 per cent participating interest in the Masela Block in Indonesia. Gas was discovered in 2000 when the Abadi-1 exploratory well was drilled. This marked the first discovery of crude oil and natural gas in the Arafura Sea in Tanimbar, Mollucas, Indonesia. A development plan was submitted to the Indonesian government and subsequently approved. Preparatory measures for Front-End Engineering Design, set to begin in the first half of 2012, are currently in process. In 2017 the company is ready to start the Pre FEED phase and hold a joint workshop with SKK Migas.
