REAL Energy has discovered gas in the first exploration well it has drilled on its permit area in the Cooper Eromanga basin.

The Tamarama 1 well, which spudded on 8 September, was cased and suspended for future testing after making the find in permit area ATP 927P.

The petrophysical evaluation, using a conservative 8 per cent porosity cut-off for pay calculation, indicated the well encountered 21 metres of net sandstone gas pay in the Toolachee Formation and 66 metres of net sandstone gas pay in the Patchawarra Formation.

Real Energy managing director Scott Brown said he was pleased with the information recovered so far.

“Real Energy is the first oil and gas player to drill in this area outside structural closure, attempting to prove up basin centred gas play in this area,” he said.

“We are very excited by the results received to date on Tamarama-1, which appears to confirm our understanding of the basin centred gas in this area.”

Results from the initial drilling program are to underpin Real Energy’s forward work plan, with successful wells to be cased and suspended for flow testing in early 2015.

In an announcement, the company said its acreage was prospective for conventional oil, shale oil and gas and basin centred gas (BCG) – low-permeability, gas-saturated reservoirs that are abnormally pressured, regionally pervasive, and lack down-dip water contacts.

Mr Brown told Oil & Gas Australia that the potential for BCG in the area had been considered previously, but was believed at the time to be uneconomic.

“These formations have been quite prolific in other parts,” he said. “We’re proving up a concept.”

The Tamarama 1 well is located 50 metres from a pipeline with spare capacity, he said, with the block surrounded by proven and producing gas and oil fields operated by Santos.

Real Energy has since committed to drilling its next well dubbed Queenscliff-1.

“Queenscliff-1 will further advance our knowledge of this exciting play within our acreage,” Mr Brown said.
