Senex Updates on Ethereal-1 Drilling in South Australia's Cooper Basin

Senex Energy Ltd., a Brisbane-based exploration and production company, provided Wednesday an update on drilling at the Ethereal-1 well in PEL 637 in South Australia's Cooper Basin.

Ethereal-1 gas exploration well (PEL 637: Senex 60 percent and operator, Origin Energy 40 percent)

The Ethereal-1 well is the second of two wells to be drilled in the southern Cooper Basin as part of Senex’s gas exploration program with Origin Energy. Both wells (Efficient-1 and Ethereal-1) are designed to evaluate material gas accumulations in the Permian section of the Allunga Trough.

Ethereal-1 reached total depth of 10,610 feet (3,234 meters) Jan. 2, and the results were on prognosis and in line with expectations. The results of Ethereal-1 also correlate to the hydrocarbon zones intersected in the Efficient-1 well. The joint venture has cased and suspended Ethereal-1 for fracture stimulation and production testing. Both wells were identified from the Bauhaus 3D seismic survey and are in close proximity to the Bauhaus-1 gas discovery.

In the northern joint venture area, Senex is continuing seismic interpretation to identify drill locations.

Senex is free-carried by Origin Energy for its share of expenditure.
