PEL 105 Cooper Basin Pirie-1 Well Prospect
The northern Cooper Basin province hosts the massive 100 MMbbl Tirrawarra Oil Field in the liquids-rich Patchawarra Trough. Austin Exploration through its farmin partner Adelaide Energy (ADE) acquired 93 km 2D seismic in 2008 to high-grade drilling targets in this proven hydrocarbon province.
- PEL 105 spans the central Patchawarra Trough from the Permit’s western limit between the Moorari and Kudrieke fields east to the huge Santos-operated Bookabourdie Field
- Re-interpretation of geophysical data has allowed ADE to identify a large hydrocarbon target between the producing Moorari and Kudrieke fields
- The Pirie-1 exploration well will be drilled in 2009 on a significant closure above the abandoned 1983 Toonman-1 well
- Toonman intersected tight hydrocarbon saturated sand in an era when fracture stimulation was in its infancy – ADE will fracture the tight sands to access un-risked P10 OOIP of 23 MMbbl and P50 OOIP 2 MMbbl.
- The 2008 Wakefield Seismic Survey acquired 93 km 2D seismic to identify and mature a range of drilling targets including around the flanks of the Bookabourdie structure.
- Proximity to pipeline infrastructure and processing facilities high-grades all discoveries in PEL
Geologic Data Suggests a Large Hydrocarbon Formation is Present
Cooper Basin Highlights
The Cooper Basin contains approximately 160 gas fields and 75 oil fields currently on production. These fields contain approximately 630 producing gas wells and more than 340 producing oil wells which feed into production facilities at Moomba in South Australia and Ballera in Queensland through approximately 5,600 kilometres of pipelines and flow lines via 15 major satellite facilities incorporating field boost compression (65 satellite compressors, 15 nodal compressors).
The Moomba facility also incorporates substantial underground storage for processed sales gas and ethane, while Ballera has a smaller underground storage system for processed sales gas.
Natural gas liquids are recovered via a refrigeration process in the Moomba plant and sent together with stabilised crude oil and condensate via pipeline to Port Bonython near Whyalla, South Australia.
Ethane is sent to Qenos in Sydney via a dedicated pipeline. Sales gas is sent to Adelaide and Sydney via pipelines from Moomba and sales gas is sent to Mt Isa and to Brisbane via pipeline.
