Karoon Gas Australia Ltd has made a second oil discovery in its three well Santos Basin exploration drilling campaign.

Oil is contained within an interbedded sand and shale interval of Maastrichtian age and has been confirmed from sampling of over a 200 metre gross section so far.

The discovery has been confirmed by wireline petrophysical, MDT pressure data, fluid sampling and mudlog analysis. Multiple fluid samples have been taken and will be fully analysed when recovered to surface. The well is positioned about 150 metres down dip from the trap crest, allowing for additional prospectivity higher in the structure.

Wireline testing of the discovery is continuing with full results expected over the coming week. The well will then drill ahead as planned, to 4573mR
