Balnaves

The Balnaves field is located in License WA-356-P offshore Western Australia. Apache operates the license, holding a 65% interest; KUFPEC Australia holds 35%.

The Balnaves field is an oil accumulation in the Mungaroo formation in a separate reservoir beneath the large gas reservoirs of the Brunello gas field. Drilled in 2009 by the Stena Clyde semisub, the Balnaves-1 discovery well is part of a series of gas exploration and appraisal wells in the Julimar-Brunello complex. The discovery well encountered 64 feet (20 meters) of net oil pay in the B20 sand – a light, high-quality oil accumulation at a depth of 10,600 to 10,700 feet (3,231 to 3,261 meters).

The Balnaves-3 appraisal well test-flowed 9,076 barrels of oil and 13 MMcf/d of natural gas from a 16-foot (5-meter) perforated section, confirming good reservoir deliverability. Balnaves-2 was a sidetrack from the discovery, and Balnaves-4 was a sidetrack from Balnaves-3.

Field Development

The field will be developed through two horizontal production wells connecting to an FPSO via subsea tie-backs. One water injection well will be used to maintain reservoir pressure, while gas will be re-injected into another reservoir to produce through the Wheatstone LNG project. Apache will lease the Armada Claire FPSO, owned by Bumi Armada, for Balnaves’ development.

The vessel has a production capability of 80,000 barrels of oil and 50 MMcm/d of natural gas and storage capacity for 750,000 barrels.

Production is scheduled for 2014, with gross peak production of about 30,000 barrels of oil per day
