Browse Basin

Located off the north-west coast of Western Australia, the highly prospective Browse Basin is home to a large number of gas and condensate discoveries, a number of which are being developed as LNG projects.

Santos has a substantial acreage position in the Browse with five exploration permits, including four operated permits. This material resource position can support multiple commercialisation options, including collaboration with adjacent resource owners for brownfield expansion and backfill of LNG projects.

In 2012, Santos made a significant gas and condensate discovery at the Crown-1 exploration well in WA-274-P, located between the Poseidon and Ichthys fields. With the well intersecting 61 metres of net gas pay, Crown looks increasingly to be Santos’ largest ever operated discovery. The Crown discovery is located close to existing and proposed LNG projects in the Browse Basin.

In August 2014, Santos made a significant gas-condensate discovery at the Lasseter-1 exploration well, located in WA-274-P approximately 35 kilometres east-south-east of the Crown discovery.
