Ann: South Erregulla - Wagina Gas Discovery, page-24

The Wagina Sandstone results from the logging while drilling, mud logs and wireline tools
confirm the presence of a conventional gas resource at South Erregulla.
The Wagina Sandstone was encountered at 4,072m MD and observed to be made up of 160m
of thick, clean and gas charged sands. The discovery is made up of two net pay zones:
• a 16 metre section of high-quality flow units with peak porosities of 14% and an average
of 9%; and
• a lower permeability gasifier section of 61 metre with an average porosity of 6%.
Both sections are measured to be gas saturated and over pressured with reservoir pressures
inferred to be in excess of 7,500 psi. The Wagina discovery will now be added to the future well
testing program to retrieve the final information required for a formal resource assessment
