Senex Energy Silverstar

$15m gas exploration announced in Cooper Basin

An Australian oil and gas producer will soon start a $15 million gas exploration operation in South Australia’s Cooper Basin.

Senex Energy will begin drilling its Silver Star-1 gas exploration well as part of a broader work program done in a joint venture with Origin Energy.

No jobs are advertised yet, but they will appear on Senex’s career page: senexenergy.com.au/working-with-us/current-jobs

“The Silver Star-1 well is an exciting step in the Senex and Origin Energy exploration project agreed in 2014 to unlock material high-risk gas acreage in the South Australian Cooper Basin. The areas on which we are focused have multi-Tcf potential, and gas exploration programs, such as this are crucial to unlocking more supply for the East Coast market,” Senex managing director and CEO Ian Davies says.

The Silver Star-1 PEL 638 tenement is joinly owned by Senex (53.75 per cent), operator Origin Energy (33.75 per cent) and Planet Gas (12.5 per cent). It is the first drilling location in the northern area of Senex’s joint venture with Origin, a staged program targeting material volumes of basin centred and stratigraphic gas in the Patchawarra and Allunga Troughs.

Aggregate project expenditure under the arrangement is up to $252m, from which $105m will be deployed on the first-stage work program including Silver Star-1.

Silver Star-1 is a high impact gas exploration well located in the northern Cooper Basin and is expected to be drilled to a depth of approximately 3.6km, with a potential lateral section of up to 1.5km.

The well follows the drilling of Efficient-1 and Ethereal-1 in the southern Cooper Basin, which were both cased and suspended having successfully intersected stratigraphically trapped tight gas in the Permian sandstones. The Ethereal-1 well was fracture stimulated and production tested, with the next step to complete a nitrogen lift test to increase gas production.
