As a result, the joint venture partners plan to run a drill stem test tomorrow morning to determine whether the interval contains moveable hydrocarbons.
Murrippi-1 is the second of two wells being drilled by the Beach-led joint venture to test prospects in the ‘oil fairway' between the Christies, Sellicks, Callawonga and Parsons oil discoveries in PEL 92 to the southwest, and the Growler and Wirraway oil discoveries in PEL 104 to the northwest.
The first well, Ballapurudda-1, was drilled in December 2007.
Murrippi-1 was primarily targeting the basal Birkhead Formation/Hutton Sandstone and Patchawarra Formation, with secondary targets in the Poolowanna and mid-Birkhead Formations.
Pre-drill P50 recoverable reserves of 600,000 barrels of oil for the Hutton formation and 0.17 million barrels for the Patchawarra Formation are estimated.
Possible ‘fill to spill' potential of the structures is in the region of 2-3MMbbls of recoverable oil.
Great Artesian is fully funding its 60% interest in Murrippi-1, estimated at $1.14 million net, while operator Beach holds the remaining 40%.
