Exploration - Our Role in Australia’s Energy Future

Exploration - Our Role in Australia’s Energy Future

Proven Success

Since mid-2009, we have announced 25 offshore discoveries.
We have discovered a total of ten trillion cubic feet of resources – more than 1.5 billion barrels of oil equivalent.

Developing Vital Energy Resources

Energy is not a luxury – it's the foundation for economic growth. Western Australia’s abundance of natural gas is emerging as a key resource for Australia and transforming it into a significant energy player on the world stage.

We’ve been a part of Australia’s history for more than 50 years. While we are proud of our achievements to date, we are building a new legacy. Our exploration and appraisal program is an important part of building economic prosperity here in Australia and around the globe.

Investing in the Search for New Energy

We are the largest exploration lease holder in Australia and we always look at opportunities to expand our resource base and add to our asset portfolio. We have an impressive queue of projects that will support energy security for Australia and drive growth for the Chevron Corporation.  Chevron is leading the investment of $80 billion worth of LNG projects on behalf of our joint venture partners which includes the Gorgon and Wheatstone projects.

We invest in leading edge technology to explore for and develop new resources. We are supported by our Perth-based Global Technology Centre which works to reduce development costs, maintain exploration success and improve recovery. Our partnerships with the WA Energy Research Alliance, CSIRO, University of Western Australia and Curtin University are vital for new research and development.

Chevron’s exploration success rates are amongst the best in the industry.

Asia-Pacific - 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.

Understanding the Region and its Geology

With 25 offshore discoveries announced since mid-2009, Chevron's exploration results are amongst the best in the industry – and demonstrate the quality of our exploration capability. In 2013, we had an 85 per cent exploration success rate – well above regional and global success rates for drilling.

We attribute our ongoing success to a combination of significant exploration funding, a detailed geological knowledge of the region, the quality of our drilling program and a commitment to technical excellence and safe operations.

Success starts with the geology.  It requires a detailed regional understanding of the potential of a basin to identify reservoirs and hydrocarbon traps. We have a talented and creative exploration team with global experience who are able to use our 70,000 square kilometres of seismic data to find new opportunities and prospects.

Technical Excellence

Since 2009, Australia has added a total of ten trillion cubic feet of resources – more than 1.5 billion barrels of oil equivalent. Our people and technology are the keys to our success. We have a talented team of scientists and engineers who interpret data with new tools and technology to find new opportunities. Our drilling and exploration campaigns are assisted by state-of-the-art drill rigs.

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. Our development drilling program represents one of the most significant investments we have made in offshore activities in Western Australia.

The Ocean America semi-submersible drilling rig is part-way through an extensive drilling program concentrating on prospects in the Exmouth Plateau and Greater Gorgon Deepwater exploration licenses.  The vessel began work for Chevron Australia in November 2013, and is capable of working in a water depth of 5,000 feet and drilling to a depth of 30,000 feet.  It has accommodation for 123 personnel.

North Western Australia Exploration Acreage Map

Great Australian Bight

We recently acquired two deepwater exploration interests in the Great Australian Bight – a deepwater frontier basin off the southern Australian coast. The acquisition nearly doubles Chevron’s offshore acreage holding in Australia. The new acreage spans more than 32,000 square kilometres and the six year program includes marine seismic surveys, geological studies and two exploration wells in each permit.

Cooper Basin

In February 2013, Chevron Australia reached agreement with Beach Energy to acquire working interests in two onshore gas blocks covering an estimated 810,000 acres in the Nappamerri Trough in central Australia.

The agreement provides an opportunity for Chevron Australia to actively evaluate and assess the potential for commercial shale and tight gas development in the prospective Cooper Basin, and potentially add to its industry-leading portfolio of natural gas projects in Australia.

The gas blocks in the Cooper Basin represent Chevron Australia's first onshore gas evaluation activity.
