Drilling is expected to take 18 days to reach a total depth of 2127 metres, Innamincka said.
Avery will fund part of the well costs to earn a 25% interest in the Aspen farmout block, a 55 square kilometre area in the south-eastern part of PEL 103 and about 8km northeast of the Cummin-1 drilled in 2004.
Containing a potential 17 million barrels of in-place oil, the Aspen Prospect’s primary targets include the Hutton Sandstone, Poolowanna Formation and sandstone units within the Triassic section.
“Fair to excellent reservoir properties - porosity and permeability - are expected to prevail in these sandstones,” Innamincka said.
“[But] effective hydrocarbon charge is considered the main risk.”
The Aspen prospect is an anticlinal structure on the broad Innamincka High - the largest structural culmination in the Cooper and Eromanga Basins, the company said.
Cummin-1 was the third well drilled on the Innamincka High to explore for a crestal hydrocarbon accumulation. Very encouraging oil shows were reported throughout the Eromanga section in addition to a small oil discovery, Innamincka said.
The first two wells – Innamincka-3 and 4 drilled in the early 1980s - also had encouraging oil shows, but failed to intersect an economic oil accumulation.
