Our business

Senex is an oil and gas business with a solid foundation and bold growth ambitions.

It is focused on growth in three areas:

  • Oil in the Cooper-Eromanga Basin
  • Gas in the Cooper-Eromanga Basin
  • Coal seam gas in the Surat Basin







Oil in the Cooper-Eromanga Basin

Cooper BasinCooper Basin

Senex is a major oil producer in the South Australian Cooper-Eromanga Basin, with a strong acreage position. The company is pursuing a rapid development strategy, targeting a significant increase in oil reserves and production capability in the short to medium term.


Gas in the Cooper-Eromanga Basin

Senex is working towards developing a large-scale, cost-competitive gas resource in South Australia's Cooper-Eromanga Basin - including both conventional and unconventional gas plays. The company gained an impressive portfolio of unconventional gas acreage when it acquired Stuart Petroleum Limited in 2011. It has subsequently expanded its portfolio through key farmins to have a commanding position in some of the Basin's most prospective areas for unconventional gas.

Senex's unconventional gas acreage includes:

  • Shales: Thick, mature Roseneath and Murteree shales
  • Coals: Thick, mature Toolachee coals and thick Patchawarra coals
  • Tight sand and coal sequences: Thick Toolachee sand and coal sequences

Senex began exploring for unconventional gas in May 2011 when it drilled Vintage Crop-1 in the southern Cooper Basin.


Coal seam gas in the Surat Basin


Senex holds four strategically located coal seam gas tenements in Queensland's booming energy hub, centred on the Surat Basin. The company's highly-productive tenements are located close to existing infrastructure and in the feedstock region of several multi-billion dollar liquefied natural gas (LNG) projects.

In partnership with experienced coal seam gas exploration companies, Senex is undertaking an ambitious exploration program to unlock significant coal seam gas reserves.
