New discovery: Australian operator looks great in Canning Basin
Main Australian onshore operator Buru Energy has discovered what appears to be a large build-up of wet gas in the remote Canning Basin in northwest Australia.
Buru and his 50:50 joint venture partner Origin Energy began an exploration campaign for two wells in the Canning in mid-April 2021. The Canning is his area of interest which contains his Ungani oil field and a multitude exploration permits.
The first well – Currajong-1 – was drilled on July 1, 2021 using the Ensign 963 platform. The well has been drilled and tested. There was good reservoir development in the Ungani dolomite reservoir, but testing failed to recover the oil.
The second well – Rafael-1 – was confirmed today as a gas and condensate find that is being prepared for production testing.
A total gross interval of 165 meters of gas column is present from 3,785 meters to 3,950 meters deep.
From the interpretation of the wireline logs, there appears to be at least 50% net dolomite reservoir section in the gas column, Buru said.

Petrophysical interpretation and wireframe recordings suggest that the net section of the reservoir is similar to the conventional dolomite reservoir at the Ungani oilfield, and Buru added that there are several features suggesting that the gas column could be more important than what has been observed so far.
A production test that Buru hopes to complete by the end of December will gather information on tank deliverability, tank fluids, tank pressures, and potential tank limits.
Eric Streitberg, executive chairman of Buru, said: “Subject to further analysis of the available data and the results of the impending production test, Rafael’s discovery has the potential to be a very large wet gas build-up in a high quality conventional dolomite reservoir, with very low CO2 content in the gas. “
“We take a methodical and thoughtful approach to the evaluation of the discovery and intend not to waste time in commercializing the resource if its potential is realized.”
“Buru Energy has been operating in the Canning Basin for many years and we have a deep understanding of the operating environment and stakeholders. Our in-depth studies of gas marketing pathways in the Canning Basin have also given us a good understanding of how a resource can be monetized. “
“The commercial value of a gas resource is greatly improved if the field is large and contains a conventional high-flow reservoir with high pressure and high liquid content, as we hope Rafael will be confirmed. We have several other critical steps to take. take to understand what we encountered at Rafael, but the indications are promising.
