Gorgon Gas ProjectIt is one of the world's largest natural gas projects and the largest single resource project in Australia's history.
Includes the construction of a 15 million tonne per annum LNG plant on Barrow Island. LNG tanks transport to international markets while domestic gas piped to WA mainlandApproval in 2007, expected to start up in 2014.

Domestic Gas Agreements
Government Grants
The Carbon Dioxide Injection Project (discussed later) is an $850 million project aimed at minimising greenhouse gases.The government has contributed $60 million towards the project.
Suggested reasons to contribute:• The government will make
$40 billion off the lifetime of the project
• Looks good to support environmental causes in the public eye
Overall Gorgon Risk
The Gorgon project had to evaluate upstream risks in LNG production, midstream risks in shipping, and downstream risks in LNG off-take agreements
Overall Gorgon Benefits
The Gorgon fields are jointly developed by Australian subsidiaries of three international energy companies – Chevron, Royal Dutch Shell and Exxon Mobil. Each sponsor has a strong credit rating and is responsible for financing its share of the project costs. This combination of strong credits adds a strong layer of comfort to the syndicate of lenders.
Upstream Risks and Benefits
• Plant Construction Risk• Each participant is responsible for
financing its respective equity share of project costs.
• Cost overrun risk mitigated by Operator having substantial stake in project
• Strong experience of Engineering, Procurement, Construction contractors (JGC, KBR, Clough & Hatch)
• Plant Operational Risk• Excellent track record from Chevron
• Gas Reserves Risk• Greater Gorgon Fields have reserves
of 40 tcf (trillion cubic feet)
Upstream Cont.
• Political and Environmental Risk
• Stable fiscal, legal and political environment in Australia
• Strategic importance to monetize Western Australia’s gas resources
Midstream Risk
• Vessel Construction Risk
• Vessel Operational Risk
• Charterer Risk• Sponsor Risk• Vessel Debt-Related
Risk
Midstream Benefits
- Strong track record in LNG shipbuilding for Hudong. - Vessel supervision to be carried out by both Mitsui OSK Lines and
ExxonMobil - Project Development Agreement to enhance shipbuilding process
and vessel quality. - Liquidated damages in case of construction delays, cost overruns
to be covered by the sponsors. - Mitsui OSK Lines and China Shipping Development are large
reputable and financially solid ship owners. - CEXIM (Export Import Bank of China) provided long term fixed
rate loan to help mitigate interest rate risk.
DownStream
Risks:
Off-take Risk: which is an agreement between a producer of a resource and a buyer of a resource to purchase/sell portions of the producer's future production.
Benefits:
Strong, robust off-taker (PetroChina & Petronet India)
Global increase in demand for LNG.
Investment Analysis
The budget for the total Gorgon project is USD $37 billion.
A massive USD $869 million debt was raised to help finance the cost of 4 massive LNG tanker ships constructed by Hudong-Zhonghua Shipbuilding.
The project is expected to spend about $20 billion on goods and services alone during the construction period.
Budget Increase for Gorgon
•Chevron has admitted that the $37 billion dollar budget will increase.
• -Increasing labour cost
• Productivity issues
• The high Australian dollar
-Half of Gorgon’s cost are in Australian dollars.
•Chevron is currently performing an assessment that will help them understand the movements in cost.
•Oil prices are 60% higher than at the time of the projects sanction.
•Chevron is still very confident that production will still be commencing around the stated schedule in late 2014.
GDP Increase Gorgon will increase
Australia’s GDP by $63 billion dollars.
Australia’s gas export are predicted to quadruple over the next decade
About $33 billion will be spent on local goods and services.
Will create about 10000 direct and indirect jobs at peak construction.
Government Attitudes• An integral role in making the project viable.• A partner, directly and indirectly
11/04/2023
Government Policies
Under current arrangements, the commonwealth will receive all royalties from the batch of looming petroleum projects in WA because the gas sits in federal waters, even though the processing facilities will be on state land.
‘it was only fair that WA should receive a share of oil and gas royalties’ -- Norman Moore
Tax Issues• PRRT (used to exclude the North West Shelf and East Timor) • The new tax - Minerals Resource Rent Tax• The expanded PRRT (Petroleum Resource Rent Tax)• Increased taxation based on their profits (super-profits tax),
not on the quantity of resource extracted• The power of government to introduce new taxes is
essentially limited to what people are prepared to pay.
CO2 Injection• Gorgon field contains about
14-16% CO2 which is removed during gas processing operations and is usually emitted via atmospheric venting
• The joint venture has invested about $2billion in the design and construction of the worlds biggest commercial CO2 injection facility and should reduce the projects emissions by 40% (3.6million tonnes/y)
• Approximately 120 million tonnes of CO2 will be safely injected underground during the life of the Gorgon Project (6x more than any project in the world), positioning Australia as a world-leader in CO2 injection technology.
• The CO2 extracted from the reservoirs will be extracted as per normal gas processing, and then compressed and injected into the Dupuy formation underneath Barrow Island
• Once injected, the CO2 will dissolve into the sandstone and become permanently stored in the underground reservoir Dupuy
• Once injection has started, a reservoir surveillance program will monitor movement of the injected CO2 and observe the effects on the reservoir.
• The movement of the injected CO2 will be monitored using time-lapse seismic data and surveillance wells to detect the arrival time and the volume of CO2 at the well
The Environment
Barrow Island was set aside as a nature reserve in 1910 in recognition of its outstanding flora and fauna values
It is currently reserved as a Class ‘A’ Nature Reserve for the purpose of ‘Conservation of Flora and Fauna’, which represents the highest level of protection afforded under State legislation
Subsea gathering systems and subsea pipelines will be installed to deliver feed gas from the Gorgon gas fields to the west coast of Barrow Island
The feed gas pipeline system will be buried as it traverses from the west coast to the east coast of the Island where the system will tie in to the Gas Treatment Plant located at Town Point
How to protect Barrow Island and surrounding waters during production and operation?
1) Devise a plan
2) Seek Approval
3) Adhere to the plan
“This Plan has been prepared to ensure that the installation and pre-commissioning of the DomGas pipeline as described in Section 3.0 is conducted in a manner that protects environmental values and reduces impacts to the environment as far as practicable”
Environmental OutcomesRisk is evaluated and defined on a scale from 1-10
(7,8,9,10) deemed acceptable
Implementation
The Inherent Risk is assessed and then management and mitigation measures are taken to reduce the risk to acceptable levels (Residual Risk)
Health & Safety
“For us, it's not about statistics – it's about keeping people safe”
Chevron – as the operator of Gorgon – is committed to making sure Health, Environment and Safety is at the forefront of all development plans
The company provides an all encompassing medical service for injury treatment and management, injury prevention programs, drug and alcohol testing and health education
Investing in the Health of the Gorgon Workforce The health of Chevron's construction and operational workforce is looked after by Medibank Health Solutions as part of a $20 million five-year contract to deliver medical personnel and services on Barrow and Thevenard islands
