Ichthys LNG Project

In 1998, INPEX acquired an exploration permit in the block where the Ichthys Gas-Condensate Field is now located, and following development studies including exploration, evaluation and FEED work, INPEX announced its FID in January 2012. Following the completion and commissioning of production facilities, INPEX commenced production in July 2018 and later began shipping condensate, LNG and liquefied petroleum gas (LPG).

Production ramp up has progressed very smoothly, and in 2019, 104 LNG cargoes were shipped from the project’s onshore gas liquefaction plant in Darwin. In 2020, shipments of approximately 10 LNG cargoes per month are expected given stable (plateau) production conditions.

Surrounding Blocks

INPEX holds interests in 20 exploration blocks in the vicinity of the Ichthys Gas-Condensate Field and has engaged in exploration activities that have led to the discovery of gas in at least 11 of these blocks. Evaluation work is now being performed on these discoveries. In the event that substantial amounts of hydrocarbons are confirmed as a result of these exploration and evaluation activities, INPEX expects to expand its business by leveraging the synergies of integration with the Ichthys LNG Project.

Prelude FLNG Project

INPEX in June 2012 acquired from Shell a 17.5% interest in the Prelude FLNG Project, which is located in WA-44-L, approximately 475 km north-northeast of Broome, off the coast of Western Australia. A production, liquefaction and shipment using FLNG, the Prelude FLNG Project consists of the Prelude and Concerto gas fields and will produce approximately 3.6 million tons per year of LNG, 400 thousand tons per year of LPG at peak and approximately 36,000bbl of condensate per day at peak.

Shell (the operator) made the FID on the Prelude FLNG Project in May 2011.

The FLNG sailed away from its construction site in Geoje, South Korea, in June 2017 and arrived in Australian waters in July 2017. After mooring work and commissioning, the initial phase of production commenced in December 2018. The FLNG facility shipped the project's first condensate cargo in March 2019, and first LNG cargo in June 2019.

INPEX acquired interests in offshore Western Australia WA-155-P (Part I) in July 1999, after which the Van Gogh and Ravensworth oil fields were discovered. The Australian Government granted production licenses for the above oil fields as the WA-35-L and WA-43-L blocks, at which oil production commenced in February and August of 2010, respectively. The development of the Coniston Oil Field, which saddles WA-35-L and WA-55-L, was started in December 2011, and crude oil production commenced in May 2015.

In April 1993, INPEX acquired an interest in the former JPDA03-12 contract area, located in the Timor Sea joint petroleum development area (JPDA), which was jointly managed by Australia and East Timor. Exploration within this contract area resulted in the discovery of oil and gas fields. Of these, studies revealed that the Undan structure and the Bayu structure, located in the adjacent former JPDA03-13 contract area, were a single structure. The interest holders unitized both contract areas in 1999, allowing joint development of the Bayu-Undan Gas-Condensate Field to proceed. The commercial production and shipment of condensate and LPG started in 2004 followed by LNG in February 2006.

In August 2019, JPDA was abolished as a result of the ratification of a maritime boundary treaty between Australia and East Timor, and the area fell under the sole jurisdiction of the East Timor government. In accordance with the treaty, discussions were held between both governments and PSC contractors. The parties agreed to keep the same conditions as the former PSC and consequently a new PSC with the East Timor government (Block title: PSC-TL-SO-T 19-12) was bound.
