In response to the deep interest in unconventional gas exploration in the Cooper Basin, and the high demand for unconventional gas well data as it becomes available, DMITRE has set up the Cooper Basin Unconventional Wells and Data web page. The web page lists the unconventional gas wells that have been drilled in the Cooper Basin, open file data release dates, and has direct links to available well completion reports and wireline log data.

Well completion reports for all publically available wells can be downloaded via SARIG

All openfile logs for other wells can be purchased from DMITRE, by emailing
