Callawonga
In a statement, the company said the Callwonga-1 well, located in Eromanga Basin permit PEL 92, started free-flowing about 2100 barrels of oil per day, which are being primarily transported via truck 40km to Tantanna, before being piped to Moomba.
Drilled in July, the well encountered 8m of net oil pay in the Namur Sandstone and flowed oil on drill stem test at a rate of 2400bopd.
Beach, which holds a 75% stake in PEL 92 with Cooper Energy (25%), said Callawonga-1 was the most westerly oil production achieved to date in the Cooper/Eromanga region and demonstrates the high oil prospectivity of PEL 92, particularly in the area west and north of the Christies field.
The joint venture recently carried out a 3D seismic survey in this region, the results of which will be used to better delineate Callawonga and identify prospects for drilling in 2007.
Beach assesses P50 recoverable oil reserves in the Callawonga Field to be 1.5 million barrels (MMbbl), of which its share is 1.1MMbbl.
Talia
Mapped using 3D seismic data, Talia-1 is an anticlinal feature located on a regional high and flanked by producing oil fields: the Sturt oil field is 3km north, Sturt East is 3km northeast and Tantanna is 4km southeast.
Beach’s junior partner in the well, Great Artesian Oil and Gas, said the wildcat would test whether oil has migrated westward of the Sturt oil field onto this regional high.
Based on the nearby oil production, primary reservoir targets have been identified as the McKinlay/Namur, Birkhead and Hutton Sandston formations, with secondary potential in the Poolowanna Formation.
With a planned total depth of 1840m, the Talia-1 well is targeting a pre-drill estimate of 320,000-800,000bbl of recoverable oil reserves if the prospect is filled to the maximum extent of the structural closure.
Expected to take 11 days to drill and three days to evaluate, Talia-1 is the third in a five-well, back-to-back program planned for PEL 107, in which Beach holds a 40% stake, Great Artesian has 40% and Magellan Petroleum, 20%.
