Over the past several years Senex has made material steps to realise the potential in the Australian east coast gas market.

Senex’s major development focus in the near term is on Project Atlas and the Glenora and Eos blocks of the Western Surat Gas Project. Together these two project areas constitute 334 petajoules (PJ) (57 mmboe) of 2P reserves, of which around 90% is currently undeveloped. The conversion of these undeveloped 2P reserves to developed reserves and production is the overwhelming priority for Senex.

The breakdown of our 1P and 2P reserves is as follows:

Senex engages the services of DeGolyer and MacNaughton (D&M) and Netherland Sewell Associates (NSAI) to independently assess reserves and resources prior to reporting any updated estimates. D&M and NSAI are independent resource estimating firms with considerable experience in the Cooper Basin and the Surat Basin respectively.
