Lakes Oil chairman Rob Annells said tests have confirmed the oil was high quality, but Lakes now needed to work out how much is there, according to an ABC Online report.
Drilling will resume early next week, Annells said.
Wombat-3 was the first onshore well to recover oil from the Strzelecki formation, Annells told EnergyReview.Net last month.
The Wombat Block is located in PEP 157. An overriding royalty of 5% of the wellhead value of any hydrocarbon production is payable to Roma Petroleum, a former holder of the permit.
