Regarding the status of offshore facilities, construction work has finished on a floating central processing facility (CPF) and a floating production, storage and of offloading (FPSO) facility. A naming ceremony for the facilities was held in the South Korean shipyards in February 2017, naming the CPF “Ichthys Explorer” and the FPSO “Ichthys Venturer.” At the end of April 2017, the CPF sailed away from the South Korean shipyard following the completion of commissioning and preparation work, arrived at the Ichthys gas-condensate field at the end of May, and mooring was completed in late June. Plans call for the FPSO to set sail for the project site soon. In other offshore-related work, installation work was finished in January 2017 on almost all of the subsea infrastructure and equipment needed to produce natural gas and condensate. The drilling of production wells is ongoing. With regard to the onshore LNG plant, INPEX has basically finished construction work on the main facilities and is currently carrying out connection work for the delivered and installed modules, as well as is making steady progress with commissioning. Looking ahead at the production schedule, installation and commissioning work will be undertaken and production from the wellhead will commence. Thereafter, the Ichthys LNG Project will, during the current fiscal year (ending March 31, 2018), begin production of condensate, liquefied natural gas (LNG) and liquefied petroleum gas (LPG) in sequence and then ship these products.

INPEX holds 14 exploration blocks in the vicinity of the Ichthys gas-condensate field and is currently engaging in exploration activities. Of this total, exploration work has led to the discovery of gas at eight blocks (WA-56-R, WA-57-R, WA-58-R, WA-74-R, WA-281-P, WA-274-P, WA-513-P, and WA-514-P). Evaluation work is now being performed on these discoveries. In the event that substantial amounts of crude oil and natural gas are confirmed as a result of this exploration and evaluation activity, synergies and other effects with the Ichthys LNG Project are expected to further expand business.

INPEX Oil & Gas Australia 17.5%
Shell* 67.5%
KOGAS 10.0%
OPIC 5.0%

In June 2012, we 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 project using FLNG, the Prelude FLNG Project consists of the Prelude and Concerto gas fields and will approximately produce 3.6 million tons per year of LNG, 400 thousand tons per year of LPG at peak and approximately 36 thousand barrels per day of condensate at peak.

Shell (the operator) made the FID on the Prelude FLNG Project in May 2011. Development of the Prelude FLNG Project is currently under way.
The Project is expected to begin contributing to the company's financial performance, including its cash flow, in 2018.

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 JPDA03-12, a contract area located in the Timor Sea JPDA, which is 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 in the adjacent 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, and LNG in February 2006.
