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.
And, 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.

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

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.

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.

Latest Exploration Success 

Our most recent discovery was in April 2015, when we announced a further drilling success in the Greater Gorgon Area located in the Carnarvon Basin.

The Isosceles-1 exploration discovery well encountered approximately 134 metres (440 feet) of net gas pay in the Triassic Mungaroo Sands in 968 metres of water (3,175 feet). The well fulfilled the second year work commitment in the exploration program. It is located in the WA-392-P permit area approximately 95 kilometres (60 miles) northwest of Barrow Island, off the coast of Western Australia. 

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.

We have a 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.

Great Australian Bight

In October 2013, Chevron Australia acquired two deepwater exploration permits (EPP44 and EPP45) in the Great Australian Bight – A deepwater frontier basin approximately 300 kilometres west of Port Lincoln off the southern Australian coast.

The acquisition spans more than 32,000 square kilometres and nearly doubles Chevron’s offshore acreage holding in Australia.

The Bight Basin is similar in size to the North West Shelf and these two blocks contain significant hydrocarbon exploration potential.

As operator with 100 percent interest, Chevron’s work program includes marine seismic surveys, geological studies and two exploration wells in each permit.

Australia’s largest 3D seismic survey in the Bight Basin now complete

The Nerites 3D seismic data acquisition program over Chevron Australia acreage in the Great Australian Bight was completed safely with 22,000 square kilometres of data acquired.

The two-stage program represents the largest seismic survey undertaken in Australasia and Chevron globally to-date.

Chevron is currently interpreting the seismic data to determine its drilling program, including drilling locations and rig selection. At this stage, it’s expected drilling would start late 2017/18.

Great Australian Bight Deepwater Marine Program

In partnership with Chevron, CSIRO is conducting an integrated field research program targeting unexplored deepwater regions in the Great Australian Bight.

The multimillion dollar program aims to assist in building an enhanced baseline picture of the sea floor environment, geology and the benthic ecology to better understand the southern continental margin. Led by the CSIRO in collaboration with a number of academic and government research agencies, including Geoscience Australia and the University of Adelaide, the program will include extensive field studies conducted in 2015 and possibly 2016.
