Santos General Manager Unconventional Resources Carl Greenstreet echoes Mr Dello’s outlook for the development of unconventional resources in the basin, commenting that although it is still early days, Santos remains encouraged by the potential of unconventional resources in Central Australia.
“Across the Cooper Basin in South Australia and south-west Queensland, and the Amadeus Basin and McArthur Basin in the Northern Territory, we have 100,000 sq km of highly prospective acreage in unconventional gas plays,” says Mr Greenstreet.
“The Cooper Basin has significant shale gas potential estimated at in excess of 80 Tcf.”
Mr Greenstreet says the success in 2012 at Moomba-191 was the first step in unlocking that potential.
“Since then we have drilled a total of 11 wells and fracture stimulated and flow tested seven, with highly encouraging gas flows from all of them. Moomba-191 continues to produce at over 1.7 MMscf/d approximately 18 months after coming online.”
Two horizontal shale wells, Roswell-2H and Moomba-193H, have since been drilled and fractured stimulated as a follow up program to the Moomba-191 result, with Moomba-193H currently online as the first shale gas producer currently flowing at 1.1 MMscf/d.
“An emerging unconventional play in the Cooper Basin is the Deep Coal Natural Gas Resource,” says Mr Greenstreet.
“The Cooper Basin’s vast oil and gas reserves have been primarily sourced by the Permian coal units and Santos is a first mover in appraising the resource and commercial potential of this new unconventional play.”
