If Yulleroo-2 is non-commercial then maybe we will not hear about these guys for some time......on the other hand, if she comes up with the goods then who knows ......I guess only time will tell.


ARC Energy Limited advises that operations at the Yulleroo-2 exploration well, operated by ARC Energy and located in the onshore Canning Basin Permit EP 391, commenced at 17:00
hours WST on 22 January, 2008. Current operation at the well is a remedial cementation of the 508mm (20”) conductor pipe before drilling ahead in 444mm (17.5”) hole. ARC is the operator and 100% equity holder in EP 391 and the Yulleroo-2 well.

Yulleroo-2 is located 75km east of Broome with good all weather access to the Great Northern Highway. The spud of the well has been delayed while operational problems with Century Rig 18 were rectified by the Contractor.

Yulleroo-2 is the third major play type to be tested in ARC Energy’s Canning Basin regional drilling program. The Yulleroo-2 well location is 2.5 kilometres to the east of the Yulleroo-1 gas discovery made in 1967. Mapping of the pre-existing seismic data over the Yulleroo structure,
including recently reprocessed data, shows a large faulted four way dip closed structural trap, with the Yulleroo-2 location mapped as being up-dip from the Yulleroo-1 gas discovery. The primary goal of Yulleroo-2 is to provide a definitive evaluation of the Yulleroo-1 gas flows to
enable a better estimate of potential gas reserves and commerciality of the Yulleroo structure.

The vertical Yulleroo-2 well being drilled to a total depth of ~3,500m will test a series of stacked
closures and is prognosed to intersect the primary objective Tournaisian Gas Sands at between
2,900 to 3,200 metres drill depth. Potential recoverable volumes in the Yulleroo prospect range
from a mean of 474 BCF of gas to a P10 of 928 BCF of gas.

Managing Director’s comments:
“We are very pleased to be spudding a well at the third location in our Canning Basin program.
Yulleroo-2 is the final well in this season’s program and has demonstrated our ability to operate in the basin well outside the weather window that conventionally has restricted operations in the area.

The previous wells in the program at Valentine/Stokes Bay and Valhalla have been extremely encouraging. The Yulleroo area is also very prospective with wet gas recoveries from the Yulleroo-1 well (albeit at low flow rates) and multiple follow-up opportunities. Seismic processing
and preliminary mapping of the recent Yulleroo 2D seismic survey has delineated leads nearby at Ungani, Big Red Roo, Jackeroo and Desperado. These leads are large, and potential reservoir volumes could be substantial, and justify the construction of ARC’s planned Great Northern Gas Pipeline designed to deliver gas to Alcoa in the southwest of Western Australia.”
