Apache has successfully tested the Spar-2 appraisal well in permit WA-4-R, offshore Western Australia.

The well test showed 58 million cubic feet of natural gas and 950 barrels of condensate per day.

Spar-2 was completed over a perforated interval of 40m within 50m of high-quality gas pay in a single zone at the top of the Barrow Group formation.

The appraisal well is located 1.6km south-west of the Halyard-1 discovery and 29km south-west of Apache’s John Brookes platform.

Apache’s Australia subsidiary will transport gas from the Spar and Halyard fields to Western Australia’s domestic gas market through an existing Apache-operated pipeline ten miles south-east of Spar-2 and through the Varanus Island processing and transportation hub.

First production from Spar is expected in late 2012 following first production from Halyard in the second half of 2011 as additional capacity becomes available at Varanus Island.

Apache owns a 55% interest in the WA-4-R permit, while Santos owns the remaining interest.
