Galilee Basin Location

  • Galilee Basin is located between

the Bowen, Cooper and Georgina Basins

  • Uncomformably overlain by the

Eromanga Basin for most part

  • Minimal existing infrastructure

Previous CSG Exploration

  • 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 to >100mD

  • Enron followed up the corehole program with single production wells at

Rodney Creek and Crossmore

  • ATP529 purchased by Galilee Energy in 2000 and a further 4 production

wells were drilled at Rodney Creek and production tested producing large volumes of water with minimal gas

  • Rodney Creek 8 corehole drilled by Galilee Energy in a more crestal

position on the Glenaras Anticline and completed desorption testing

  • ver entire stratigraphic coal interval
  • Gas contents higher than past results
  • Saturation between 50% and 70%
  • Confirmed good to moderate permeability

Previous Exploration

»Galilee CSG Exploration »PESA Symposium 2010

  • Rodney Creek 8 gas

contents much higher than previously found

  • Difference from

Previous Rodney Creek wells thought to be due to testing methodology on

  • lder wells
  • Quick crush
  • Discreet sampling
  • Ambient

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 1:
  • Drill and complete a production pilot
  • Construct water holding facilities and production test wells
  • Stage 2
  • Drill 7 coreholes
  • Acquire 500km 2D seismic
  • Reprocess 2000km 2D seismic

AGL/Galilee Energy Exploration Program

  • Stage 1:
  • Production pilot drilled and completed – 2 under-ream and 3

fraced wells

  • 380 ML produced water holding pond constructed
  • Wells placed on pump, though currently shut in due to pump

issues

  • New pumps to be installed over the next month
  • Stage 2
  • 5 coreholes drilled, 6th currently coring, 7th top hole

completed

  • Acquired 541km 2D seismic
  • Reprocessed 2231km 2D seismic, mainly 1981 to 1985 data

Well and Seismic Locations

  • Exploration program

designed to appraise all ATP529P

  • Corehole program has

targeted several different types of play

  • Glenaras step out wells

to assist in field delineation

  • Thick preserved Triassic

cover for higher gas saturations

  • Thick Permian coal

bearing packages identified from seismic

Galilee Gold Rush

  • At time of AGL Farm In

minimal exploration was underway

  • Majority of basin was not

covered by tenure

  • Acreage release by QLD DME in

August 2008 combined with AGL Farm In renewed exploration interest

  • Currently most of basin

covered by tenure

  • CSG well density has tripled

from 13 to 38 wells1 and increasing

AGL/Galilee Energy Results

»Galilee CSG Exploration »PESA Symposium 2010

  • Crossmore South and Vera

Park 1 identified similar coal packages and gas contents as Rodney Creek 8

  • Acacia 1 and Mt Myth 1 were

drilled in areas where thick Triassic cover was preserved

  • Initial gas content results

suggest values lower than Glenaras and Rodney Creek, decreasing towards the north- east

AGL/Galilee Energy Results

»Galilee CSG Exploration »PESA Symposium 2010

  • Wells targeting thick coal

package yielded positive results

  • Laugharne Creek 1 targeted a

thick Permian section approximately 180ms thick compared to an average of 100ms at Glenaras

  • Multiple clean seams

encountered over a 340m interval

  • Aramac Coal Measures much

thicker than previously encountered

Gas Content Trends

  • Gas content for the Galilee Basin is generally low
  • Previous results range from <1m3/t at Splitters Creek 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

identified to date

  • Results by depth show no particular trend, however when viewed by

area a trend is apparent

Gas Content Variation

  • Possible causes in variation…
  • Gas stripped from coal due to meteroic water flushing of seams?
  • Higher heatflow associated with granite emplacement in the

Maneroo Platform locally raising temperature increasing gas generation?

  • However..
  • Gas composition and limited isotope values show thermogenically

derived gas on the western side of the Koburra Trough, no biogenic addition

  • No gas composition, isotope data or coals seam water is open file or

exists for eastern wells to confirm water flushing or gas source

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
  • ne
  • Glenaras 4 drilled in late 2008 transitioned from Allaru Mudstone

into Wallumbilla Fm, Toolebuc Fm absence initially thought to be due to small scale local faulting

  • The Sardine seismic survey acquired in late 2009 provided good

definition of the Toolebuc Fm across ATP529P

  • Apparent frequent faulting throughout the Toolebuc and Wallumbilla

formations was observed on all lines with minimal structure seen to propagate through the Cadna-Owie Fm

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 may not succeed, any development would require dense seismic imaging, most likely 3D, to accurately map out all structure

  • Toolebuc Fm has a gross average thickness of 15m within ATP529

further reducing its attractiveness as an exploration target

So what does this mean for ATP529P

  • Historical testing appears to have underestimated gas contents
  • Gas thermogenically generated
  • Southern portion of permit is more prospective than northern

portion

  • AGL and Galilee Energy are encouraged with results to date
  • Further work based on final DAF gas contents and additional

saturation values would assist in better defining trends

  • The addition of more eastern and central Koburra Trough Wells

would make a more robust interpretation

  • Shale gas potential in Toolebuc Fm appears limited due to faulting

and thin formation
