SHALE GAS• The US Energy Information
Administration has estimated that the entire Cooper Basin (SA and QLD) has a risked recoverable shale gas resource of 85 Tcf
![Page 11: UNCONVENTIONAL HYDROCARBON PLAYS IN THE PERMIAN SUCCESSION …](https://reader034.fdocuments.in/reader034/viewer/2022052106/6287ed0a2a41e9139408ef8f/html5/thumbnails/11.jpg)
SHALE GAS
ADSORPTION CAPACITY is a function of a number of parameters including:• Organic carbon content• Organic maceral type and maturity (surface area)• Temperature
~ 24 scf/t at 3800 psi, T = 167.8°C

SHALE GAS
DIFFERENT TO TYPICAL NORTH AMERICAN SHALE GAS PLAYS
• Lower organic carbon contents, organic maceral type (Type III) and high temperatures mean that ADSORBED gas contents for Roseneath and Murteree shales will be significantly lower than for typical North American shale plays.
NOT TRUE SELF SOURCING SHALE RESERVOIRS?
• Some of the gas in the Roseneath and Murteree shales may have migrated from other source units
SILTSTONES
• A much higher percentage of gas stored as FREE gas in pore space.

• Glacial topography created when Australia lay near the south pole is preserved in the subsurface
• The Permian sediments infilling this topography offer a variety of hydrocarbon resource plays
• Exploration for continuous gas plays in the Cooper Basin is progressing well with gas flows from fracture stimulated vertical wells exceeding 2 mmcf/d.
• Assessment of resource plays in the Arckaringa and Pedirka basins is less advanced at this stage, with play fairways yet to be identified.
