Ex PEL 100 (BAS ~74% PRL 207-209)

Ex PEL 100 encompasses PRL 207–209 and is 296 km² in area. It contains the Cleansweep oil discovery and is adjacent to the Cuttapirrie oil and gas field and the Verona gas field.

PRL 209 contains the Cleansweep oil discovery. The well discovered oil in a channel in the lower Birkhead reservoir. The well was suspended after producing almost 10,000 barrels of oil with much of the production equipment remaining on location making it possible to quickly return the well to production. 

Cleansweep was drilled without the benefit of a later acquired 3D seismic survey. The seismic will be interpreted with a view to targeting the upside potential of a Birkhead channel reservoir. 

The licence also contains the Athelstan oil prospect which a previous operator has assessed to be an unrisked, mean prospective resource of 1.2 million barrels of oil within the Poolowana, Birkhead and Tinchoo formations. Athelstan has been identified with the benefit of Dundinna 3D seismic survey and is on trend with the Santos owned and operated Keleary oil field. 

The license contains several oil prospects, which a previous opeartorhas assessed to be a mean unrisked prospective resource of 4.8 million barrels of oil (JV share). The potential exists in the Tinchoo, Poolawanna and Birkhead target horizons.
