Commercial success with shale gas well in the Cooper Basin

The Moomba-191 shale gas well in the Cooper Basin has flowed gas at a stabilised rate of 2.6 million standard cubic feet per day (mmscf/d) from the Roseneath, Epilson and Murteree (REM) shale targets for over two weeks.
This result enables Santos to announce Australia’s first commercial production of gas from a shale well.
Moomba-191 is a dedicated vertical shale gas well located in licence PPL 7 (Santos 66.6%), approximately eight kilometres north-east of the Santos-operated Moomba gas plant in South Australia.
The well is located within 350 metres of existing gas gathering infrastructure.
Connection activities have commenced and the well will be tied-in to Santos’ existing gas gathering infrastructure this year.
The well is another milestone for Santos’ Cooper Basin unconventional gas program, which commenced in 2004, and follows other Santos firsts including Australia’s first shale fracture and coring program in 2006 and first independently certified shale and unconventional resource bookings in 2008.
Moomba-191 was drilled to a depth of 3,010 metres with the aim of appraising the gas potential of the REM unconventional gas targets in the Moomba North area. Thickness and properties, including gas content, of the REM were consistent with pre-drill expectations, reflecting the extensive technical understanding arising
from Santos’ long involvement and operation of conventional activities in these fields.

Each of the REM intervals was fracture stimulated and monitored via microseismic in an adjacent well. By only stimulating the shale zones of Moomba-191, Santos has gathered valuable data to assist in the design of future shale gas wells, including a dedicated horizontal shale gas well in the Moomba North area planned for early next year.

Following well stimulation, completion and clean-up activities, Moomba-191 has been producing dry gas at a stabilised rate of 2.6 mmscf/d and has reached 3 mmscf/d through a 52/64” choke.
These flow rates are an excellent result considering Moomba-191 is a vertical shale well primarily designed for data gathering. Initial analysis of the gas composition indicates the CO2 content is consistent with that historically produced in the Moomba North area of the Cooper Basin.
CEO David Knox said shale gas flows from Moomba-191 were a significant strategic milestone in Santos’ program to unlock the vast unconventional gas potential of the Cooper Basin.
“The data we have gathered from the well will be critical in the design of both our first horizontal shale gas well, which we plan to drill early next year, and the ongoing vertical well appraisal program, of which Moomba-191 is a part,” Mr Knox said.
