Udacha-1 is about 12km northwest of the Moonanga gas field and 17km east of the Sellicks oil field.
The Udacha prospect is primarily a Permian oil and gas play. The well will test the hydrocarbon potential of a faulted anticlinical closure at the Patchawarra level.
Secondary potential existed in the Tolachee and Epsilon formations and Tirrawarra Sandstone, according to Beach.
The well’s planned total depth is 2775 metres. It is expected to take about 19 days to drill and evaluate.
After drilling Udacha-1, the Century 3 rig will move about 5km southwest to drill Middleton-1 in PEL 106, due to spud in early February.
Participants in Udacha-1 are operator Beach Petroleum (15%), Great Artesian Oil and Gas (32.5%) Magellan Petroleum Australia (30%, subject to commercial discovery), Enterprise Energy (12.5%, subject to commercial discovery), and Rawson Resources (10%, subject to commercial discovery).
