Karoon Gas Australia has informed that as at 2000 hrs BRST on December 2, 2014, wireline logging of the Kangaroo-2 appraisal well, offshore Brazil, was complete and preparations were underway to run the 9-5/8” test casing prior to starting the production testing program which will take place over the coming weeks.
Karoon announced the spudding of the Kangaroo-2 well in November, 2014. The company says it will provide the next Kangaroo-2 appraisal well progress report following the completion of the production testing program. A decision on a potential side-track and coring program will be made on completion of the testing program, Karoon adds.
Following the completion of all operations on the Kangaroo-2 appraisal well, the rig will be moved to drill and evaluate the Kangaroo West prospect approximately 4.5 kilometres distant on the western side of Kangaroo salt structure. The Kangaroo-2 appraisal well is located in block S-M-1165, approximately 300 metres updip and 4 kilometres South of Kangaroo-1 and is the first well in the current Santos Basin exploration and appraisal drilling campaign. According to Karoon, the information obtained from Kangaroo-2 will be crucial for assessing the commerciality of the Kangaroo oil field and will be the basis for the Front End Engineering and Design (’FEED’) phase bringing the project a step closer to commerciality. Karoon holds a 65% interest in, and is operator of the jointly held S-M-1165 block, Santos Basin.
Upcoming Well Program
The exploration and appraisal drilling campaign, operated by Karoon, is expected to continue through first half 2015.
The rig contract provides Karoon with 2 firm wells plus 2 option wells, and, in the event of a successful drilling in the first 2 wells provides maximum flexibility for further appraisal of the Kangaroo oil discovery, including testing and appraisal of the Kangaroo West prospect.
Following Kangaroo-2, the second firm well in the program is the Kangaroo West-1 exploration well. The company says that 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 salt flank play was first proven by Kangaroo-1 with the intersection of a 76 metre gross oil column and oil recovered to surface from wireline DSTs. Results of the Kangaroo-2 further confirm the viability of the play, the company says. 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.
The ’Olinda Star’ semi-submersible drilling rig is drilling the entire drilling program.
