Senex Spuds Paning-2 Unconventional Gas Well

Senex Energy has commenced its 12 well unconventional gas exploration program with the spudding of the Paning-2 well in northern Cooper Basin permit PEL 90. The targeted total depth of the well is 3,175 metres.

Paning-2 is located 1.2 kilometres southwest of Paning-1, which was drilled in 1980 by Delhi Petroleum as a conventional gas exploration well. The Paning-2 well is the first unconventional gas exploration well to be drilled in the region and is designed to provide valuable information about the potential for gas production from the tight sands and deep coal seams of this new region, Senex said in a statement.

The Paning-2 well is the first exploration well to test the potential of the Permian tight sand sequence that exists within the entire Patchawarra Trough.

Paning-2 will test massive Permian coals known to exist throughout the Patchawarra Trough where Senex holds an extensive acreage position. Data from the desorption of Permian coals cored in previous Senex wells indicates gas contents of at least 600 standard cubic feet per tonne (equivalent to approximately 17 cubic metres per tonne). The productivity of the Permian coals was proven by Santos at the Moomba-77 well, where Patchawarra Formation coals flowed at 100,000 cubic feet per day.

The unconventional gas target located in deep coal seams within this 9,000 acre structure is estimated to contain potential gas in place of 2.1 Tcf.
