In September 1998, INPEX acquired an interest in the Offshore North Caspian Sea Contract Area in Kazakhstan’s territorial waters. The Kashagan Oil Field is located within this area in the Caspian Sea where the water reaches depths of 3-4 meters, approximately 75 kilometers southeast of Atyrau, Kazakhstan. Following the drilling of the first exploratory well in September 1999, the Kashagan Oil Field was discovered in 2000 and commercial quantities of oil were confirmed in 2002. After development work, the shipment of crude oil commenced in October 2016. INPEX and its partners have achieved the project’s initial production volume target of 370,000 barrels per day and are currently working to increase the daily production volume to 450,000 barrels.

Meanwhile, the presence of hydrocarbons has been confirmed in the Kalamkas, Aktote and Kairan structures, which are located adjacent to the Kashagan Oil Field. Appraisal of these three structures is being conducted in parallel with the development of the Kashagan Oil Field, with a view to expanding the total production of the contract area.

INPEX acquired an interest in the Azeri-Chirag-Deepwater Gunashli (ACG) oil fields in the south Caspian Sea offshore Azerbaijan in April 2003. At the ACG oil fields, oil is being produced at the Chirag, the Central Azeri, the West Azeri, the East Azeri, the Deepwater Gunashli and the West Chirag locations. In September 2017, INPEX and its partners agreed with the State Oil Company of the Azerbaijan Republic (SOCAR) to extend the duration of the production sharing agreement (PSA) for the ACG oil fields by 25 years until December 31, 2049. The revised PSA came into effect in January 2018.

In April 2019, INPEX and its partners made the final investment decision (FID) on the further development of the Azeri-Chirag-Deepwater Gunashli (ACG) oil fields through the commissioning and deployment of a new production platform. The new platform is expected to commence production in 2023 with the aim of expanding the volume of proved reserves and enhancing the project’s value.
