Senex Upgrades Cooper Basin Gas Resources

Senex Energy has upgraded its its contingent gas resources in the South Australian Cooper Basin to 5.5 trillion cubic feet (Tcf) following analysis and interpretation of recent gas exploration results by Senex and independent estimators DeGolyer and MacNaughton.

The upgrade includes initial 2C and 3C contingent resources at the conventional Hornet gas field (PEL 115 and PEL 516) and ascribes initial contingent resources at Sasanof (PEL 516) and Paning (PEL 90).

The Hornet contingent resource is specific to the tight gas sands that occur at an average depth of about 2,500 metres. This area is known to be low in CO2, with potential for significant condensate yields, Senex said.

Contingent resources at Sasanof in southern Cooper Basin permit PEL 516 are estimated across both the tight sands of the Patchawarra formation and the Murteree Shale that flowed in excess of 200,000 cubic feet per day during testing of the Sasanof-1 well. Contingent resources at Paning in northern Cooper Basin permit PEL 90 (Senex 100%) are contained within the Toolachee coals that flowed at a maximum rate of 90,000 cubic feet per day during a four day production test from the Paning-2 well. This is one of the most significant results to date from deep coals within the Cooper Basin.

Senex Managing Director Ian Davies said the upgrade was a major step forward for the company’s gas development strategy and increased the level of confidence in the quality of the resource in the South Australian Cooper Basin.

“This is a terrific result for Senex that presents a realistic opportunity to significantly add to the productive capacity of a proven hydrocarbon province, which has already produced around 6 Tcf of gas,” Davis said.
