Since beginning its activities in Australia in 1993, Apache Energy has invested more than A$5 billion in acquisitions, field development and exploration.

Today, it holds 167 million barrels of oil equivalent in reserves and operates production of approximately 19,000 barrels of oil and condensate per day and 365 terajoule (TJ) per day of gas in Western Australia. It holds 7.6 million acres, including exploration permits and production licenses, in the Carnarvon, Browse and Gippsland Basins in offshore Australia with a number of new projects coming on line in the next few years. 

Varanus Island

Varanus Island, approximately 75 kilometers (km) offshore northwest Australia, is the hub for the Harriet Joint Venture and John Brookes Joint Venture oil, condensate and gas gathering infrastructure. Apache is operator of both joint ventures, and is a 68.5 percent owner of the Harriet Venture and a 55 percent owner of the John Brookes Joint Venture.

Facilities include a fixed conventional oil platform at Harriet, monopod platforms at Victoria, Double Island, and John Brookes platform; oil processing facilities and 750,000 barrels of liquid storage; five gas plants, two sales gas pipelines to the main West Australia's gas trunklines and an oil export system.

Production for the two joint ventures is approximately 8,000 Bpd of oil and condensate and 365 TJ/d of gas.

This operation is West Australia’s second largest domestic gas facility and caters for approximately 30 percent of West Australia's gas demand. Oil produced by the Harriet and John Brookes joint ventures is blended and sold to a variety of customers throughout Australia and Asia.
