Karoon encounteres multiple oil bearing zones at Kangaroo-2 appraisal well

MELBOURNE, Australia -- Karoon Gas has completed drilling at the Kangaroo-2 appraisal well, located in Block S-M-1165 in the Santos basin, offshore Brazil, at a total depth of 2,369 mRT (meters below rotary table) and encountered multiple oil bearing zones.

Five separate oil bearing reservoir sand intervals over the interval 1,660 mRT to 2,000 mRT in the Palaeocene and Maastrichtian age formation have been penetrated, with each interval having a separate oil/water contact.

The gross oil column thickness totals 250 m, and no gas cap was penetrated.

The Palaeocene section contains a 90 m gross oil bearing reservoir with a net to gross over 70% and porosities in the range of 26% to 34%. Three separate oil columns are present with sampling estimates of 40 degree API oil with a Gas Oil Ratio (GOR) of 500 scf/bbl.

The Maastrichtian section contains two oil bearing reservoirs. At the top of the Maastrichtian, an 85 m gross oil bearing reservoir interval has a net to gross over 60% and porosities in the range of 22% to 26%.

The lower Maastrichtian oil bearing reservoir interval has a thickness of 75 m, a net to gross of 25% and porosities in the range of 21% to 25%. Oil recovered from the Maastrichtian reservoirs is estimated to be 40 degree API with a GOR range of 550–700 scf/bbl.

Karoon holds a 65% interest in, and is operator of the jointly held S-M-1165 block in the Santos basin.
