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.

Harriet Joint Venture

Apache has a 68.5 percent interest is the operator.  The Harriet Joint Venture currently produces 5,000 Bpd and 120 TJ/d of gas. To date, 495 petajoules (PJ) of gas and 82.5 million barrels (MMBbl) of oil and condensate have been produced.

East Spar Joint Venture

Apache has a 55 percent interest and is the operator. Gas and condensate production commenced in November 1996 with the completion of two subsea development wells, East Spar-1 and East Spar -3. East Spar -6 was added to production in 2003. Production from the East Spar field ceased in 2006 and further appraisal work is being completed in the areas for further developments.

John Brookes Joint Venture

Apache has a 55 percent interest and is the operator. The John Brookes field was discovered in 1998 and successfully appraised in 2003.  First production began in September 2005. Located 35 km from East Spar and 55 km northwest of the Varanus Island Hub, it currently produces 245 TJ/d of gas and 2,800 Bbls of condensate.  

Legendre

Apache has a 77.4 percent interest and is the operator. The Legendre facility is located approximately 150 km north of Karratha in Western Australia. The facilities include the Ocean Legend, a mobile offshore production unit, and the Karratha Spirit, a floating storage and offtake vessel. The field commenced production in May 2001, with peak production of 45,000 barrels per day (Bpd). Currently the field produces approximately 3,000 Bpd, with production jointly sold to various Australian and Asian traders and refiners.

Stag

Apache has a 33.3 percent interest and is the operator. The Stag facility is located approximately 60 km northwest of Dampier in Western Australia. The facility includes a conventional platform connected to the Dampier Spirit, a floating storage and offtake vessel. The field has been producing oil since May 1998, with current production of approximately 7,000 Bpd sold to a variety of customers throughout Asia.

Van Gogh

Oil production commenced in February 2010 at our Van Gogh development in Production License WA-35-L in the Exmouth Basin, offshore Western Australia. Apache, the Van Gogh field operator, owns a 52.5-percent interest in the field with INPEX owning the remaining interest. Van Gogh is located 32 miles (53 km) north-northwest of Exmouth. Van Gogh, discovered in 2003, is Apache's first field development utilizing a floating production, storage and offloading (FPSO) vessel. The field was developed with 19 horizontal production laterals, two water injection wells and one gas injection well. The total horizontal interval drilled for all of the production wells exceeds 106,000 feet (32 km). The Ningaloo Vision FPSO has capacity to process 150,000 barrels of liquids per day, including 63,000 barrels of oil per day, and store 540,000 barrels of oil. www.apachevangogh.com.au

Pyrenees

Production commenced at the nearby BHP Billiton-operated Pyrenees FPSO development project in March 2010. Apache owns a 28.6-percent working interest. Production from the Crosby, Ravensworth and Stickle wells processed through the floating production, storage and offloading (FPSO) vessel at Pyrenees is expected to be brought on in phases, with approximately half the field ramping up from first oil and the other half over the next six months.
