Tests results released Monday for the Karoon Gas operated Kangaroo-2 appraisal well in offshore Brazil confirmed a “significant” oil deposit at the shallow water discovery.

The Kangaroo-2 appraisal well was drilled in Block S-M-1165, about 943 feet up-dip from the Kangaroo-1 discovery well.

A production test conducted over a 12 hour period through three perforated intervals in the Paleocene A, B and C sandstone reservoirs confirmed a 820 foot gross oil column Paleocene and Maastrichtian aged reservoirs.

A maximum flow rate of 3,700 barrels per day of 33 degree API oil was attained through an 88/64 inch choke with a gas-oil-ratio of 540 cubic feet per barrel and no water or sand production, Australia-based Karoon said.

A separate production test was conducted across the 59 foot lower perforated interval in the Paleocene C reservoir that achieved a maximum flow rate of 2,500 barrels per day through with a gas-oil-ration of 450 cf/bbl.

Production testing in the current Kangaroo-2 well bore is now complete and two side-track wells are being planned to better define the resource size and recovery factors at the well.

Karoon operates Block S-M-1165 and holds a 65 percent interest in Kangaroo-2.

Ontario-based Pacific Rubiales Energy holds a 35 percent interest in the well.
