Neutron-Density cross-plot suggests water bearing Waarre sandstone with

10 – 15% porosity range.

No gas effect

Unlikely to be any oil as no fluorescence

Pickett plot for the Waarre sandstone indicates water with resistivity of approx 0.1 ohm.m at 96 deg C

(0.253 ohm.m at 25 deg C – 23,250 ppm NaCl equiv)

Childers Cove 1• Using the water saturation from the Waarre sandstone,

the lower sandstone is calculated to have a gas saturation up to approx 50%

• Using net sand / net pay cut-offs of– Vsh < 40%, Porosity > 8%, Water saturation < 60%

• Interval 2580 – 2622 mRT– Net sand 14.7 metres, Porosity 11.3%– Net Pay 11.7 metres, Porosity 11.7%, Sw 50%
