Western Gas (519 P) Pty Ltd plans to drill the Sasanof-1 exploration well in Exploration Permit WA-519-P, located in Commonwealth waters in the Carnarvon Basin offshore from Western Australia. The target hydrocarbon prospect is a light Group I condensate. Drilling is planned to commence at the earliest in Q1 2022 and could occur any time between Q1 2022 and Q4 2023, subject to approvals, vessel availability and weather constraints. Drilling activity are expected to take approximately 25 days. The Sasanof-1 location is about 156 km north of North West Cape (Exmouth area) and 207 km northwest of Onslow. Approximate water depth at the drilling location is 1,070 m. The Sasanof-1 well will be drilled using a semi-submersible mobile offshore drilling unit (MODU), which will be anchored to the seabed or, depending on rig availability, a dynamically positioned MODU may be used as an alternative. Activity support vessels will include general supply/support vessels and anchor handling vessel(s). The activity will also be supported by helicopter operations, primarily for passenger transfers/crew changes and minor supplies, but may also be used in the event of an emergency evacuation. Remotely operated vehicles will also be used. For the duration of drilling activities a 500 m temporary Petroleum Safety Zone will be in place around the MODU and a 5 km radius temporary Operational Area (Cautionary Area) will be in place around the well location. Drilling activities will be undertaken 24 hours per day, 7 days per week. |
