Karoon Gas Australia (Karoon) has said that it expects to commence the 2-4 well appraisal and exploration drilling campaign during the second week in November 2014

The primary objective of the upcoming drilling programme is to drill the lower risk appraisal well in the Kangaroo oil discovery.

During July 2014, Karoon contracted the Queiroz Galvao semi-submersible drilling rig, the Olinda Star to complete up to four wells in Karoon’s 65 per cent 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.

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. 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 up dip 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.

The second well in the programme is the Kangaroo West-1 exploration well, targeting a net un-risked prospective resource of 330 mmbbls. 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.

The play type for Kangaroo West-1 is proven at Kangaroo-1 with the intersection of a 76-metres 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.
