Karoon to drill Kangaroo-2 in November (Brazil)
- Business & Finance
Karoon Gas Australia has informed the company expects to start the 2-4 well appraisal and exploration drilling campaign in the Santos Basin, off Brazil, during the second week in November 2014.
The primary objective of the upcoming drilling program is to drill the lower risk appraisal well in the Kangaroo oil discovery, off Brazil.
During July 2014, Karoon contracted the Queiroz Galvao semi-submersible drilling rig, the Olinda Star to complete up to 4 wells in Karoon’s 65% owned and operated Santos Basin blocks, S-M-1037, S-M-1101, S-M-1102, S-M-1165 and S-M-1166. The rig is currently completing operations with Petrobras and hand over of the rig is expected in the next 2-3 weeks.
Low risk appraisal drilling
The Kangaroo-2 appraisal well is designed to confirm the size of the oil column, the presence and size of a possible gas cap, reservoir continuity and properties, and flow rates. Karoon says this information will be crucial for assessing the commerciality of the Kangaroo oil field and, which upon success, will be the basis for the Front End Engineering and Design (’FEED’) phase bringing the project a step closer to commerciality.
The Kangaroo-2 appraisal well is located approximately 300 metres updip from Kangaroo-1 and will test the thick reservoir sequence observed in all surrounding wells. It is anticipated that a 350 metre plus gross hydrocarbon column will be intersected in this well.
Exploration drilling in a proven play type
The second well in the program is the Kangaroo West-1 exploration well, targeting a net un-risked prospective resource of 330mmbbls. Due to the large size and proximity to Kangaroo, a successful outcome at Kangaroo West-1 would materially add to any possible development of the Kangaroo oil field, Karoon explains in the release.
The play type for Kangaroo West-1 is proven at Kangaroo-1 with the intersection of a 76m gross oil column and oil recovered to surface from wireline DSTs. Kangaroo West-1 is located on the western flank of the same salt structure as Kangaroo-1 and has the same trap type and reservoir and seal intervals that have been mapped into the prospect from surrounding wells.
Rig contract provides maximum flexibility
The rig contract provides Karoon with 2 firm wells plus 2 option wells, providing maximum flexibility for further appraisal of the Kangaroo oil discovery, including testing and appraisal of the Kangaroo West prospect in the event of a successful drilling in the first 2 wells.
