Regional Geological Setting and Shale Gas Plays

Potential gas shales in Ontario

Same plays as in NE U.S. and Quebec

Best potential in:– U. Devonian Kettle Point Fm (Antrim shale equivalent) – M. Devonian Marcellus Formation– U. Ordovician Blue Mountain Formation and

Collingwood shale (Utica equivalents)• Gas shows, no current production• Unexplored (only one shale gas exploratory well)• Large prospective areas

Maturity Studies• Obermajer, Fowler & Snowdon, AAPG 1999

• Core, cuttings, outcrop

• Most samples are mature, in oil window

• Increase in maturity to southeast (Repetski et al, 2008)

• Lack of samples in southeast where shales are thickest – gas window?

Biogenic or Thermogenic ?

• No direct evidence for any of the Ontario shales

• Natural gas in drift and bedrock over prospective shales is associated with fresh water and may be biogenic

• Shallow, low temperature• Antrim shale in Michigan is at least in part

biogenic• Best potential for thermogenic gas may be in

the deeper thermally mature Blue Mountain / Collingwood shales

Summary

• Shale gas potential in Kettle Point, Marcellus, and Blue Mountain / Collingwood formations

• Large prospective areas• Thermally immature to mature• Favourable depths and thicknesses • Natural gas shows reported – large number in Kettle

Point formation• Gas is there - Can it be commercially recovered?• Research project initiated by Ontario Geological Survey
