Exploration - Our Role in Australia’s Energy Future

Exploration - Our Role in Australia’s Energy Future

We are Creating History

Our exploration rates are amongst the best in the industry.

We have made 21 offshore discoveries in Western Australia since mid-2009, underpinning potential expansions of the Gorgon and Wheatstone Projects.

Developing Vital Energy Resources

We’ve been a part of Australia’s history for over 60 years. While we are proud of our achievements to date, we are building a new legacy. For us, now is the time to invest in the future and our exploration and appraisal program is an important part of that future investment.

Energy is not a luxury – it's the foundation for economic growth. And by investing in the future, we're helping to build economic prosperity both here in Australia and around the globe. Right now, we’re undertaking our biggest drilling campaign in Australia as well as the largest ever 3D Seismic Survey in the country.

Investing in the Search for New Energy

Australia remains one of Chevron's global exploration focus areas.

Our recent success in Australian waters highlights the quality of our exploration capability in the region and the significance of Australia to Chevron's energy portfolio globally.

Chevron Australia has achieved unprecedented exploration success offshore Western Australia with 21 discoveries since 2009.

Atwood Osprey drill rig

In May 2011, Chevron Australia took delivery of the Atwood Osprey drill rig. The rig is a sixth generation ultra-deepwater semi-submersible rig able to conventionally moor in up to 2,438m (8,000 feet of water) and accommodate up to 200 people.

Asia-Pacific is Rich with Opportunities

As we aspire to build an Asia-Pacific gas business here in Australia, we will continue to expand our already substantial holdings. We hold the largest natural gas resource position in Australia in the prized offshore North West Shelf region. Our operated interest spans more than 42,000 square kilometres of acreage and our non-operated interests across more than 14,000 square kilometres - including our 16.7 percent participation in the North West Shelf Venture.

Our campaign involves deepwater semi-submersible drilling in the Greater Gorgon Area, Exmouth Plateau and the Wheatstone area.

A History of Success

With 21 offshore discoveries since mid-2009, it is clear why Western Australia is central to Chevron's global strategy of building an internationally competitive gas business in the Asia Pacific region.

Exploration is a big part of our business. Globally, Chevron's exploration results are amongst the best in the industry - and our performance in Australia has largely contributed to that success.

We have a strong history of exploration success both in terms of quantity and quality of discoveries. The Acme-1 discovery announced in August 2010, remains one of our most significant natural gas discoveries in Australia in terms of net gas pay.

We attribute our on-going success to a combination of significant exploration funding, the quality of our drilling program and a commitment to technical excellence and safe operations.

Technical Excellence

In mid-2011, Chevron Australia took delivery of the Atwood Osprey drill rig. The rig is a sixth generation deepwater semi-submersible rig able to conventionally moor in up to 2,438m (8,000 feet of water) and accommodate up to 200 people.

It is a purpose-built rig, which underpins our long-term commitment to find, appraise and develop Australian gas resources for domestic and international markets. The rig is involved in drilling exploration wells as well as drilling development wells for the Gorgon Project. Our development drilling program represents one of the most significant investments we have made in offshore activities in Western Australia.

The Atwood Eagle, a second rig we have contracted to Chevron Australia for the current drilling program, is a semi submersible rig with a maximum water depth of 5,000 feet and a drilling depth of 25,000 feet. Successful discoveries would be linked to facilities already operating or being planned – in turn providing substantial benefits to Australia.

Gorgon

Over the past few years numerous natural gas discoveries have been made in the Carnarvon Basin - offshore north Western Australia - to bolster supply for the Gorgon Project and its potential expansion. The extensive drilling program contained several exploration and appraisal wells within various permits in the Greater Gorgon area.  The work to prepare for this program involved extensive seismic processing and interpretation, geological modelling and detailed well planning.

For Chevron Australia, these gas finds represent long-term activity undertaken to mature exploration prospects via a mixture of desk-top studies and acquisition and analysis of seismic data. And while the gas finds in the Greater Gorgon acreage support the company’s long-term growth plans for Gorgon, our drilling successes underpin Chevron’s plan to build an internationally competitive gas business to supply energy to Australia and the Asia Pacific.

Wheatstone

In 2011, two wells Acme West-1 and Acme West-2 located in the WA-205-P permit area added additional resources adjacent to the significant Acme discovery.

The discoveries are expected to help support potential expansion opportunities at the Wheatstone liquefied natural gas (LNG) hub.  

Exmouth Plateau

In the Exmouth Plateau, Chevron has announced a number of discoveries in this frontier region.

The Elfin-1 (WA-268-P) and Kentish Knock South-1 (WA-365-P) exploration discoveries were announced in the first quarter of 2013, marking Chevron Australia's 20th and 21st discoveries since mid-2009. During 2010 and 2011, we announced the Brederode-1 discovery (WA-364-P) and Vos-1 discovery (WA-439-P).

These discoveries continue to grow our discovered gas portfolio in Australia.
