Karoon Gas Australia Ltd. reached an agreement with QGOG Constellation S.A. to contract the semisubmersible drilling rig Olinda Star. The contract includes the drilling of up to four wells offshore Brazil, in Karoon’s S-M-1037, 1101, 1102, 1165 and 1166 blocks.
The rig contract consists of two firm wells, the Kangaroo-2 appraisal well and the Kangaroo West-1 exploration well, and two option wells. The drilling campaign is expected to begin during September 2014 with the Kangaroo-2.
According to Karoon Gas executive chairman, Robert Hosking, the main goal is to appraise the Kangaroo oil discovery.
“The Kangaroo-2 appraisal well is designed to confirm the size of the oil column, reservoir continuity and properties, and flow rates for the Kangaroo oil discovery,” says Hosking. “This information will be crucial for assessing the commerciality of the Kangaroo field, and on success, will be the basis for the front-end engineering and design phase.
The two option wells will provide flexibility for further appraisal and testing of Kangaroo and Kangaroo West, in the event of a further discovery.
In 2013, Karoon Oil & Gas along with partner Pacific Rubiales announced the discovery of a 25m light oil column at their Kangaroo-1 exploration well on Block S-M-1101 in the Santos Basin. 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.
Karoon holds and operates 65% of the blocks in the Santos Basin, with Pacific Rubiales Energy who holds the remaining 35%.
