Slide 3: Galilee Basin Location
2 Galilee Basin Location • Galilee Basin is located between the Bowen, Cooper and Georgina Basins • Uncomformably overlain by the E Eromanga B Basin i for f mostt partt • Minimal existing infrastructure »Galilee CSG Exploration »PESA Symposium 2010
Slide 4: Previous CSG Exploration
3 Previous CSG Exploration p • During the early 1990’s Enron as holders of ATP529P drilled several coreholes with the best results located at Rodney Creek and Crossmore • 40% to 50% saturation with pipeline quality gas composition • Thick coal intervals up to 35m net with good to moderate perm, 5mD
Slide 5: Previous Exploration
4 Previous Exploration p • Rodney Creek 8 gas Gas Content DAF Vs Depth contents much 9.00 higher than Rodney Creek 8 8.00 previously found 7.00 • Difference from Diff f 6.00 Previous Rodney ntent (m3/t) Creek wells thought 5.00 to be due to testing Gas Con 4 00 4.00 methodology on 3.00 older wells 2
Slide 6: AGL Farm In
5 AGL Farm In • In July 2008 AGL entered into a Farm In agreement with Galilee Energy for 50% of ATP529P • The Farm In is in two stages • Stage g 1: • Drill and complete a production pilot • Construct water holding g facilities and p production test wells • Stage 2 • Drill 7 coreholes • Acquire 500k
Slide 7: AGL/Galilee Energy Exploration Program
6 AGL/Galilee / Energy gy Exploration p Program g • Stage 1: • Production d i pilot il ddrilled ill d and d completed l d – 2 under-ream d and d3 fraced wells • 380 ML p produced water holding gppond constructed • Wells placed on pump, though currently shut in due to pump issues • New pumps to be in
Slide 8: Well and Seismic Locations
7 Well and Seismic Locations • Exploration program designed to appraise all ATP529P • Corehole program has t targeted t d severall diff differentt types of play • Glenaras step p out wells to assist in field delineation • Thick preserved Triassic cover for higher gas saturations • Thick hi k Permian
Slide 9: Galilee Gold Rush
8 Galilee Gold Rush • At time of AGL Farm In minimal exploration was underway • Majority of basin was not coveredd by b tenure t • Acreage release by QLD DME in g August 2008 combined with AGL Farm In renewed exploration interest • Currently most of basin covered by tenure • CSG well density has tri

Slide 11: AGL/Galilee Energy Results
10 AGL/Galilee / Energy gy Results • Crossmore South and Vera Park 1 identified similar coal packages and gas contents as Rodney Creek 8 • Acacia A i 1 andd Mt M Myth th 1 were drilled in areas where thick Triassic cover was preserved • Initial gas content results suggest values lower than Glenaras
Slide 12: AGL/Galilee Energy Results
11 AGL/Galilee / Energy gy Results • Wells targeting thick coal package yielded positive results • Laugharne Creek 1 targeted a thi k P thick Permian i section ti approximately 180ms thick compared to an average of 100ms at Glenaras • Multiple clean seams encountered over a 340m interval • Aramac Co

Slide 16: Gas Content Trends
15 Gas Content Trends • Gas content for the Galilee Basin is generally low • Previous i results l range ffrom <1m3/t/ at S Splitters li C Creek k up to >7m3/t / at Rodney Creek 8 giving saturations of 52% to 67% at Rodney Creek 8 • Rodney Creek 8 has the highest gas contents and saturations identifi

Slide 19: Gas Content Variation
18 Gas Content Variation • Possible causes in variation… • G stripped Gas i d ffrom coall d due to meteroic i water flushing fl hi off seams? ? • Higher heatflow associated with granite emplacement in the Maneroo Platform locally y raising g temperature p increasing g gas g generation? • However.. •
Slide 20: Shale Gas Observations
19 Shale Gas Observations • The Toolebuc Fm is found throughout the Eromanga Basin with ATP529P being no exception • All wells drilled to date have encountered the Toolebuc Fm except one • Glenaras 4 drilled in late 2008 transitioned from Allaru Mudstone into Wallumbilla Fm, Toolebuc Fm absence init

Slide 22: Shale Gas Observations
21 Shale Gas Observations • Initially thought to be an issue with the acquisition or processing of the seismic, till the absence of the Toolebuc Fm in Glenaras 4 was applied • While faulting of this nature would not be a reason shale gas production d ti may nott succeed, d any development d l t woul
Slide 23: So what does this mean for ATP529P
22 So what does this mean for ATP529P • Historical testing appears to have underestimated gas contents • G thermogenically Gas h i ll generated d • Southern portion of permit is more prospective than northern p portion • AGL and Galilee Energy are encouraged with results to date • Further work based
