Santos is the biggest producer of domestic gas in Western Australia and has been operating in the west since its first offshore discovery, in the Carnarvon Basin, in the early 1980s.
The company also has a strategic infrastructure position in WA, with interests in three of the State’s major domestic gas plants, at Varanus Island, Devil Creek and Macedon.
Gas, condensate and oil from the offshore John Brookes, Harriet and Spar-Halyard fields is piped to the Santos-operated Varanus Island processing facility. The sales gas is then transported to mainland WA via two 100-kilometre pipelines, where it is supplied to major mining and industrial customers. Oil and condensate are stored on the island and transferred to tankers for direct export.
Gas and condensate from the offshore Reindeer field are transported to the Santos-operated Devil Creek processing plant, near Karratha, via a 105-kilometre pipeline. Gas from the offshore Macedon field is piped to the Macedon Domestic Gas Plant near Onslow. Sales gas from both facilities is compressed and sent to the WA domestic gas market.
Santos will continue to pursue near-field exploration opportunities and build on its position as the leading supplier of gas to the WA market.
The Van Gogh oil project comprises three offshore fields – Van Gogh, Coniston and Novara – serviced by the Floating Production Storage and Offloading (FPSO) vessel, Ningaloo Vision, operated by Santos and located approximately 40km north of the North West Cape.
The Pyrenees oil project, comprising the Crosby, Ravensworth and Stickle offshore fields, and serviced by the Pyrenees Venture FPSO vessel, is stationed approximately 25km north of the North West Cape.
The company has also had exploration success in the Carnarvon’s Bedout Sub-basin, with the Dorado and Roc discoveries, and in the Browse Basin, with the Crown and Lasseter discoveries. In 2019, a successful appraisal programme de-risked the development options for Dorado, which is forecast to have an initial gross oil production rate of between 75-100 kbbl per day.
