Its name was an acronym for South Australia Northern Territory Oil Search.
Santos made its first significant discovery of natural gas in the Cooper Basin with the Gidgealpa 2 well in 1963. The Moomba 1 discovery in 1966 confirmed this region as a major petroleum province.
As a result of these discoveries, Santos had a commercially viable quantity of gas and entered into gas sales agreements with the South Australian Gas Company, the Electricity Trust of South Australia and the Australian Gas Light Company. Gas supplies commenced in 1969.

The 1980s saw Santos develop a major liquids business following the discovery of oil at Tirrawarra in central Australia in the early 1970s. A liquids recovery plant was built at Moomba, South Australia along with a fractionation and load-out facility at Port Bonython.
By the 1990s Santos had become a major Australian operating enterprise with interests in United States and United Kingdom petroleum provinces and in emerging areas such as the Timor Sea and Carnarvon Basin in Western Australia.
A number of acquisitions in the 1990s provided Santos with additional opportunities onshore and offshore Australia, Indonesia, Malaysia, Vietnam and Papua New Guinea.
In 2011 the Santos GLNG project was sanctioned. The project is due to produce first gas in 2015.
In 2014, Santos celebrated 60 years since being incorporated on 18 March 1954.
