The company in December 2012 has shut the well at the completion of Kockatea swabbing operations, to observe pressure build-up characteristics of the fracture stimulated zone.

Norwest Energy is currently conducting a pressure and temperature gradient survey to confirm fluid interfaces in the wellbore, and to measure existing reservoir pressure at the perforations.

The company said the study of surface pressure and sonic fluid level data has showed that the reservoir has move towards its original pressure, with positive signs the reservoir is able to recharge.

Flow back operations and a detailed monitoring and evaluation program is also undergoing, after the discovery of both oil and gas flowing from the Kockatea Shale interval, post the hydraulic fracture stimulation in September 2012.

Around 78% of injected fracture fluids were recovered after swabbing the well to a maximum planned depth of 2,600m, during flow back.
