Australia's AWE said Monday that it is flowing gas at its Woodada Deep-1 onshore shale gas exploration well in Western Australia.
Two shale zones – targeting the Middle Carynginia and Upper Carynginia – were fractured with gas recovered to the surface. According to the company's update on Monday, gas flow is continuing with declining water rates.
The Middle Carynginia formation lies between 7,776 feet to 7,956 feet (2,370 meters to 2,425 meters) while the Upper Carynginia formation lies between 7,490 feet to 7,644 feet (2,283 meters to 2,330 meters).
"Measurement of gas flow rates will not be able to be made until clean-up and flow back of the well has been completed, which is expected during the next week," AWE said in a statement. "The forward plan is to continue clean up and flow back operations, collect gas samples for analysis and measure production data," AWE added.
After gas samples from the Middle Carynginia and Upper Carynginia formations are analyzed, AWE will start hydraulic fracture stimulation of a third formation above the Upper Carynginia formation, AWE's managing director Bruce Clement told Rigzone on Monday.
AWE is also involved in the nearby Arrowsmith-2 shale well, which is currently flowing gas through hydraulic stimulation. The company also aims to flow gas through hydraulic stimulation at the Senecio-2 well at a later date, Clement disclosed to Rigzone.
All of the three wells are located in the North Perth Basin.
The Woodada Deep-1 well – fully owned by AWE – is located within Licence 5. Arrowsmith-2 and Senecio-2 are sited in Exploration Permit 413 (EP 413) and Licence 2 (L2) respectively. AWE holds a 44.252 percent interest in EP 413 and a 50 percent interest in L2.
