Santos Begins Appraisal Program Offshore Western Australia

Santos has started its Carnarvon Basin exploration and appraisal program offshore Western Australia. The company has spud it Bligh 1 exploration well using the Sedco 703 semisubmersible recently. Other wells included in this program are Immortelle 1, and two appraisal wells, Mutineer 3 and Exeter 3.

The Bligh 1 exploration well is in Santos' WA-191-P permit, which also holds the Mutineer and Exeter oil fields discovered earlier this year. Immortelle 1 will be drilled in the TP/7(1) permit south of Barrow Island. The Mutineer 3 and Exeter 3 appraisal wells will be drilled back-to-back mid-October to optimize a development plan for the Mutineer and Exeter fields. The Bligh 1 well is 10 kilometers east of the Mutineer discovery and is targeting an upside oil resource potential of 50 million barrels. It will be drilled in waters 156 meters deep and is expected to take 19 days. The well will test the same reservoir as encountered in the Mutineer/Exeter discoveries. The second confirmed oil exploration well, Immortelle 1, is scheduled to spud in mid-October within the Carnarvon Basin, but south of Barrow Island in the TP/7(1) permit. Partners in WA-191-P are Santos as operator with 33.4%, KUFPEC with 33.4%, Nippon with 25%, and Woodside with the remaining 8.2%.

Partners in TP/7(1) are Santos as operator with 43.71%, Apache with 39.66%, Mobil with 12.47%, and Pan Pacific Petroleum with the remaining 4.16%.
