The company’s Australian subsidiary plans to bring gas from the Spar Field and nearby Halyard Field to Western Australia’s domestic gas market via an existing Apache-operated pipeline 10 miles southeast of Spar-2 and through the Varanus Island processing and transportation hub.
First production from Halyard of approximately 50mmcf per day is expected in the second half of 2011 with Spar following in late-2012 as additional capacity becomes available at Varanus Island.
Apache owns a 55% stake in both WA-4-R and adjacent Permit WA-13-L, where Halyard is located, while Santos owns the remaining interests.
Spar-2 was completed over a perforated interval of 131ft within 163ft of high-quality gas pay in a single zone at the top of the Barrow Group formation.
The appraisal well is located about one mile to the southwest of the Halyard-1 discovery and approximately 18 miles southwest of Apache’s John Brookes platform.
The Halyard-1 discovery, drilled in 2008, test-flowed at a peak rate of 68mmcf of gas and 936 barrels of condensate per day from 91ft of net pay in the Cretaceous Halyard sandstone.
