Special Report 1: Ichthys LNG Project

WA-285-P
WA-37-R

INPEX participated in an open bid
conducted by the Australian Federal
Government for the WA- 285-P block,which is located off the coast of Western
Australia about 200 km from the Kimberleyregion. In August 1998 we acquired theexploration permit for this block. In the ﬁrst
drilling campaign, three exploratory wells
were drilled and discovered the presenceof gas and condensate from March 2000.
We then conducted a 3-D seismic survey.
A second drilling campaign began in2003, and three exploratory wells weredrilled that resulted in conﬁrmation of theextent of gas and condensate. Furtherwells were drilled beginning in 2007.
Through these endeavors, we conﬁrmed
sufﬁcient recoverable reserves of gas andcondensate for commercial development.

The Ichthys LNG Project is the ﬁrst large-scale
LNG project undertaken by a Japanese company
as an operator. The target for FID is Q4 2011,
and the production start target is Q4 2016.

10km

We are currently proceeding withfront-end engineering and design (FEED)
activity, securing government approval,
LNG marketing activities and ﬁnanceactivities, with an FID target of Q4 2011.
After FID, we will begin with detailed
engineering work on both the onshore andoffshore facilities, followed by equipment
procurement and the construction of theLNG plant and other facilities. The target
date for production startup is Q4 2016.
In August 2006, INPEX was granted
Major Project Facilitation status for theIchthys Project by the Federal Minister
for Industry, Tourism and Resources.
This status recognizes the fact that thisproject would contribute to the long-term
economic development of Australia.

Environmental Impact Survey andContribution to Regional Communities
INPEX is working closely with theAustralian Federal and Northern Territory
Governments and other Australianstakeholders, as well as people associatedwith the project, to ensure that the Ichthys
Project proceeds as planned.

About the Environmental
Impact Survey

One of two large-scale LNG projects in which INPEX iscurrently engaged, Ichthys is an enormous gas and condensate
ﬁeld discovered in 2000 by us about 200 km offshore from
Western Australia. We will build offshore production facilities,
an 889-km subsea gas export pipeline and an onshore LNG
plant, with production targeted for Q4 2016.
Production volume(expected):

LNG 8.4 million tons/year
LPG 1.6 million tons/year
Condensate approx. 100,000 bbl/d (peak rate)

FID target:

Q4 2011

Production start target: Q4 2016

At the offshore rig

INPEX is conducting an environmental
impact survey in accordance with guidelines
established by the Australian Federaland Northern Territory Governments toassess the impact of aspects of the Ichthys
Project. These included the environmental
impacts of the offshore processing andproduction facilities, the subsea pipeline
and the planned LNG plant (near Darwin
in Australia’s Northern Territory). We
submitted a draft Environmental Impact
Statement (EIS) summarizing these
activities to both governments in April
2010. This report was submitted for public
review during the period July–September
2010, and the opinions of a variety of
stakeholders were taken, focusing on thosein the Darwin area where the LNG plant will
be built. By June 2011, INPEX had been
granted environmental approval for theIchthys Project from the ministers of theAustralian Federal and Northern Territory
environmental agencies based on the EIS.

The name “Ichthys,” which means“ﬁsh” in ancient Greek, is derived
from the many fossilized ﬁsh thatwere discovered in onshore areas inclose proximity to the block.

Project History

Support for Local Communities
In proceeding with the Ichthys Project,
INPEX places great importance oncommunications with local communities
and building a relationship of mutual
understanding with the indigenouspeople of the project area. INPEX seeks
to be considered as a trusted corporate
citizen, and therefore we do our utmost
to deepen communications with people
in local communities.
In the case of the Ichthys Project,
our efforts include providing vocational
training opportunities for young people,
such as local indigenous peoples, throughthe donation of approximately AUD2
million for the construction of the Larrakia
Trade Training Centre. The goal of theschool, which opened in April 2011, is toenable students to earn qualiﬁcations
that will help them develop their careers,and currently 300 students are enrolled
to learn professional skills. In addition,
INPEX donated to those affected by theQueensland ﬂoods.

Project Development Concept
Onshore Facilities

Offshore Production Facilities
FPSO

These are composed of a central processing facility(CPF) for the separation of natural gas and condensate
and a ﬂoating production storage and ofﬂoading (FPSO)
vessel for the storage and ofﬂoading of condensate.

The FPSO receives condensate from theCPF and handles storage (storage capacity
1.2 million barrels) and shipments (85,000bbl/d peak). Some of the natural gas is repressurized and sent back to the CPF.

■Condensate: 85 thousand bbl/d (peak rate)

These are composed of the LNG plant andonshore storage facilities. The planned site forthese facilities is Blaydin Point, which is acrossthe harbour from Darwin.
■LNG: 8.4 million tons/year■LPG: 1.6 million tons/year■Condensate: 15 thousand bbl/d (peak rate)

Outline of Development Concept
LNG: 8.4 million tons/year
Production volume:

Condensate: 100 thousand bbl/d (peak rate)
LPG: 1.6 million tons/year

Subsea development wells:

30 wells at Brewster, 20 wells at Plover

Reservoir depth:

Approx. 3,900 m - 4,600 m

Subsea production facility:

Flowline, ﬂexible riser, etc.

Offshore production facility: CPF + FPSO
Gas export pipeline:

42” subsea pipeline (approx. 889 km)

Darwin onshore facilities:

Produce, store and ship LNG, LPG andcondensate

CPF
Processes the product received via theﬂexible risers from the development wells,
separating it into gas and condensate.

Onshore storage tankcapacity:
Natural gas

C3 Tank: 1 × 85,000 m³

C4 Tank: 1 × 60,000 m³

100km

200km

Gas Liquefaction Plant
The gas liquefaction plant will extract
condensate and LPG from the natural
gas pumped via the pipeline. Using
two trains, the liquefaction plant willthen cool the remaining natural gas
to –162°C to form LNG. It will handle
shipments of approximately 8.4 million
tons/year of LNG, 1.6 million tons/yearof LPG and 15,000 bpd of condensate.

These are pipes for transporting
product from the seabed to the CPF.
