Karoon Gas Australia has encountered light oil at the Kangaroo-1 exploration well on Block S-M-1101 in the Santos Basin off Brazil, partner Pacific Rubiales announced on 25 January 2013.

Karoon drilled the Kangaroo prospect to 3,049mRT. Mudlog, wireline petrophysical and MDT pressure data confirmed the presence of a 25m oil column in the Eocene, which was not the primary target.

"The discovery of oil in the Eocene reservoir at the Kangaroo-1 well provides additional information with respect to other potential prospects within the Karoon blocks," Pacific Rubiales said in a press statement. "The well exhibited good oil shows at the base of the Miocene aged carbonate layers, but these are still under a detail evaluation to determine their potential."

The well intersected the Eocene reservoir section 300m down dip from the trap crest. Karoon estimates that the entire trap holds a potential gross hydrocarbon column of approximately 350m.

A wireline program is underway with full results expected within days. Karoon said that it will determine whether to run a drill stem testing program after the wireline evaluation is completed.
