Rafael initial flow tests promising

Sasanof-1 exploration well

Buru Energy has revealed that, after some minor operational delays, Rafael-1 testing commenced on 25 February and gas flows to surface accompanied by condensate were obtained during the initial cleanup flow. 

During the initial stabilised portion of the cleanup period, gas rate was estimated to be between 4 and 5 million cubic feet per day (mcfpd). 

The indicative condensate gas ratio was estimated to be between 20 and 30 barrels of condensate per million cubic feet of gas; however, these are field measurements and need to be verified with continued sampling and lab analysis. 

According to Buru, field measured gas quality was “excellent”, with only 2 per cent observed carbon dioxide (CO2) content. 

The test program was suspended on 27 February due to cyclone warnings with all crew safely demobilised from the well location.

Once precarious conditions pass, the test will resume with a longer flow period and the acquisition of separator samples to determine the condensate and liquid petroleum content more accurately.  

Buru executive chairman Eric Streitberg said this is the first sustained gas flow from conventional reservoirs in the Canning Basin, demonstrating the producibility of gas at Rafael. 

“We now need to obtain the additional flow data and gas analysis from this test and integrate these into our reservoir models,” said Streitberg.
