Bonaparte Basin

The Bonaparte Basin is located in coastal waters off the north coast of Australia, straddling the border between Western Australia and the Northern Territory, and is one of Australia’s most significant gas provinces.

Santos has had a long and important association with the Bonaparte Basin, with its interests including the producing Darwin LNG project, the Petrel, Tern and Frigate fields, the Caldita Barossa gas fields, as well as exploration acreage.

Santos is a founding partner in Darwin LNG, which commenced production in 2006. The 3.7 mtpa LNG plant, located at Wickham Point, draws its gas from the offshore Bayu-Undan gas and condensate fields, located 500 kilometres north-west of Darwin.

Along with its partners in the Darwin LNG project, Santos is exploring multiple feed gas options to backfill and expand the Darwin LNG facility, which has government environmental approval to expand the site up to 10 million tonnes per annum.

2017 Marine Seismic Surveys

In 2017, Santos is planning to undertake two three dimensional (3D) marine seismic surveys in the Commonwealth waters of the Bonaparte Basin. The first survey, called Fishburn, is proposed for exploration permit WA-459-P, and the second survey, called Bethany, is proposed for exploration permit NT/P85.
