Slide 4: Types of Shale - Background
Types of Shale - Background Thermogenic: a conventional HC source without migration pathways Primary biogenic: shallow depth in a biogenic kitchen with limited migration Secondary biogenic: meteoric waters & anaerobic bacteria generate gas Free Hydrocarbons: all production from porosity - (Barnett –
Slide 5: Toolebuc Geology
Toolebuc Geology • Organic rich shale found across the basin (up to 20% TOC, average 9.5%) • Depth range surface – 900m across EXE permits • Over 25,000km2 of shale, up to 40m thick • Uncertain thermal maturity and therefore uncertain resource type - gas, oil or both? • Uncertain lithological and ge
Slide 6: Typical Toolebuc gas response

Slide 7: Toolebuc Shale Potential
Toolebuc Shale Potential • Two main facies • Facies A in the Western Eromanga higher ratio of Limestone to organic matter • Facies B, in NE Eromanga 70% to 95% organic rich compared to limestone www.exoma.net 7

Slide 13: Toolebuc Challenges
Toolebuc Challenges • Mobile hydrocarbons are present: – Wet gas shows when intersected – C1 to C5+ – Oil shows in conventional and water well drillers’ logs – Anecdotal evidence of gas flows in water bores • Not the generic “Barnett Shale” analogy as seen in the USA and Cooper Basin. • Potentially
Slide 14: Toolebuc Update
Toolebuc Update • Two dedicated Toolebuc wells cored to date – currently coring third well • Further 2 CSG wells have intersected Toolebuc, with 5 more CSG wells planned for 2011 • Cores are currently on desorption – producing gas • Bessies-1: Live liquid hydrocarbons discovered. Tests ongoing on re
