Chevron Gorgon Project: Australia's LNG Mega-Project

Overview

The project is operated by Chevron, which holds approximately 47.3% interest. Other major partners include ExxonMobil (25%), Shell (25%), as well as smaller stakes held by Japanese companies Osaka Gas, Tokyo Gas, and Chubu Electric Power.

The project is located on Barrow Island, which is a Class A Nature Reserve, meaning it is a highly protected area with strict environmental regulations.

The total cost of the Gorgon Project was originally estimated at around $37 billion but has since ballooned to over $54 billion due to delays, cost overruns, and other challenges.

Key Components

• Gas Fields: The Gorgon and Jansz-Io gas fields are located in the Greater Gorgon Area in the Carnarvon Basin, offshore Western Australia. These fields contain an estimated 40 trillion cubic feet of gas.

• LNG Production: The project includes the construction of three liquefied natural gas (LNG) trains, each with a capacity of 5.2 million tonnes per year, making the total capacity around 15.6 million tonnes per year.

• Domestic Gas Plant: Besides LNG production for export, the project also includes a domestic gas plant that supplies natural gas to the Western Australian market.

• CO2 Injection Project: A significant feature of the Gorgon Project is its carbon dioxide injection project, which is one of the world's largest. This involves the capture of CO2 produced alongside natural gas, which is then injected into deep underground reservoirs beneath Barrow Island. The goal is to reduce the project's greenhouse gas emissions.

Discovery of the Gorgon Gas Fields

The Gorgon gas fields were first discovered in the early 1980s, marking the beginning of what would eventually become one of the world's largest and most complex natural gas projects.

Timeline of Key Events

• 1981: The Gorgon gas field was discovered by West Australian Petroleum Pty Ltd (WAPET), a joint venture that included Chevron, Shell, and BP. This discovery was followed by the identification of the Jansz-Io field in 2000, located about 130 kilometres west of Barrow Island, further adding to the potential of the project.

• 1994: Initial feasibility studies began for the development of the Gorgon field. However, due to the remoteness of the fields and the challenges associated with developing such a large-scale project, progress was slow.

• 2003: The Gorgon Joint Venture was officially formed, comprising Chevron, ExxonMobil, Shell, and other partners. This formalized the collaborative effort to develop the gas fields and build the necessary infrastructure.

• 2005: The Australian federal government granted environmental approval for the Gorgon Project, allowing the development to proceed on Barrow Island, a Class A Nature Reserve. This approval came with stringent environmental conditions to protect the island's ecosystem.

• 2007: Chevron announced the discovery of additional gas resources in the Jansz-Io field, which would be integrated into the Gorgon Project. This bolstered the project’s resource base and justified further investment.

• 2009:

  • September: Chevron and its partners made the final investment decision (FID) to proceed with the Gorgon Project. The FID represented a significant milestone, with an initial cost estimate of $37 billion. This decision came after years of planning, regulatory approvals, and securing long-term contracts with customers, particularly in Asia.

  • November: Construction officially began on Barrow Island, with the development of infrastructure such as the LNG plant, pipelines, and subsea facilities.

• 2014: The project was hit by significant delays and cost overruns, with the budget revised to over $54 billion. These issues stemmed from a combination of technical challenges, harsh weather conditions, and logistical complexities associated with working in a remote and environmentally sensitive area.

• 2016:

  • March: The first LNG production from the Gorgon Project commenced, marking a major achievement after years of challenges. The first LNG cargo was shipped to Japan, one of the project’s key customers.

  • December: Full production capacity was reached as all three LNG trains became operational.

Project Delays and Cost Overruns

Causes of Delays

1. Technical Challenges:

   The project required the installation of extensive subsea pipelines and facilities, some of the most advanced in the world. The technical complexity of laying pipelines in deep water and connecting remote gas fields to the LNG plant on Barrow Island contributed to delays.

   Building three LNG trains on an isolated island posed significant challenges. The construction required the importation of vast amounts of materials and equipment, often from overseas, which led to logistical bottlenecks.

2. Regulatory Hurdles:

   Barrow Island’s status as a Class A Nature Reserve meant that Chevron had to adhere to strict environmental regulations. Meeting these requirements, such as protecting the island’s unique wildlife and ecosystems, added complexity and time to the project.

   Securing the necessary permits for construction and operation was a lengthy process, involving multiple layers of government oversight and public consultations.

3. Market Conditions:

   The final investment decision was made during a period of global economic uncertainty following the financial crisis (2008-2009). While the decision proceeded, the crisis had lingering effects on capital availability, cost of materials, and investor confidence.

   The project was initially planned when LNG prices were relatively high. However, as the project progressed, global LNG prices became more volatile, putting pressure on the project's financial metrics and timelines.

4. Logistical Issues:

   The remoteness of Barrow Island presented significant logistical challenges. All materials, equipment, and personnel had to be transported to the island, leading to delays, especially during adverse weather conditions.

   Western Australia experienced labour shortages during the construction phase due to a booming mining industry. This competition for skilled workers led to higher costs and delays in project timelines.

Impact of Delays and Overruns

The initial budget of $37 billion was significantly exceeded, with the final costs estimated at over $54 billion. This increase was due to a combination of the factors mentioned above, as well as unanticipated technical difficulties and regulatory compliance costs.

The project was originally expected to commence production in 2014, but the first LNG was not produced until 2016. This two-year delay impacted the project’s financial returns and delayed revenue generation for the partners.

The delays and cost overruns attracted criticism from investors, analysts, and the public. Chevron and its partners had to manage expectations and justify the additional costs to stakeholders.
