Senex Energy fracking at Australian well

Senex Energy has announced that it has completed a multi-zone hydraulic fracture stimulation programme at the Sasanof-1 unconventional gas exploration well in the Cooper Basin, South Australia.

The stimulation programme tested four intervals within the Permian section through a 4½in cased test well, fracture stimulating the upper and lower Patchawarra tight sands, as well as the Roseneath and Murteree shales.

Senex Energy managing director Ian Davies said the company’s exploration programme is focused on gathering data that will inform and shape its continuing investigations to prove up a world-class unconventional gas resource.

"In evaluating the success of this unconventional gas well, gas flow to surface is one of several key measures," he said.

"Other important measures of success include the presence of condensate and heavy gases, as well as low carbon dioxide levels."

During the flow-back stage at the site, the company will measure and observe the behaviour of the well to check gas deliverability and quality with preliminary test results expected in about two weeks.

Senex now plans to carry out post-stimulation clean-up work at Sasanof-1, located in PEL 516, to remove fracture stimulation fluid and any excess sand from the well bore.
