Santos Spuds Roc South-1 Well Offshore Western Oz
Santos has started drilling the Roc South-1 well offshore Western Australia, partner Carnarvon Petroleum said June 18.
Since completing operations at the Dorado-2 well, the Noble Tom Prosser jack-up drilling rig has arrived at Roc South-1, about 15 km northeast of Dorado-1, and has drilled the surface hole down to around 195 metres measured depth in preparation for installation of surface casing, Carnarvon said.
Roc South-1 is in the WA-437-P permit offshore Western Australia. The joint venture partners are Carnarvon (20%) and Santos (80%, operator). The well is targeting similar structure and hydrocarbons to Dorado.
Last year, Carnarvon said the Dorado discovery in the North-West Shelf offshore Western Australia holds 283mn barrels of oil equivalent of proven and probable contingent resources. The total is made up of 171mn barrels of oil, 16mn barrels of condensate and 552bn ft3 of gas, the company said. Following the Roc South-1 well, the rig is scheduled to drill the Dorado-3 appraisal well.
