Barossa Gas Project: Learn more

Founded in 1954, the South Australia Northern Territory Oil Search (SANTOS) has been safely and sustainably developing resources first across Australia, then the Asia Pacific and is now a global energy company.

In 1963, Santos pioneers discovered natural gas in the Gidgealpa 2 well, located in the Cooper Basin region. Later in 1966, our Moomba 1 site confirmed this region as a major petroleum province.

As a result of these discoveries, Santos had a commercially viable quantity of gas which enabled sales agreements with the South Australian Gas Company, the Electricity Trust of South Australia and the Australian Gas Light Company in 1969.

1963

First significant discovery

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, 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.

1980s

Tirrawarra discovery

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.

1990s

Major Australian enterprise

A number of acquisitions in the 1990s provided Santos with additional opportunities onshore and offshore Australia, Indonesia, Malaysia, Vietnam and Papua New Guinea.

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 Western Australia.

2011

In 2011 the Santos GLNG project was sanctioned. First production of LNG was announced on 24 September 2015.
