Hi Geodud:

Could you explain a bit more about the fracturing issue you have brought up.  I am not a geologist so I am not sure I have this correct, but this is my understaning.  Please feel free to correct me.

My understanding of the Canol shale is that it is tectonically fractured and this is good thing as naturally fracturing increases recovery factors in shales.  There is a paper done by the Canadian Geologic Society on this.  My understanding it was fractured by the collision of the Alaska plate which resulted in the uplift of the Franklin and McKenzie Mountains with the Central Mackenzie Valley between.

The Canol Shale is a very brittle shale containing a mostly quartz and very little clay.  Hence it readily fractures.  This is considered a very good thing from the point of hydraulic fracturing.  Imagine the difference between trying to shatter clay vs glass. 

This is why the first discovery well in the NWT in 1920 was a Canol oil well which blew out and sent oil 50 feet in the air.   Shale don't normally have enough permeability to naturally flow unless they are fractured.  It is great if nature fractures the shale rather having to do it artifically with huge pumping units.  Nature is better at things than engineers.

Husky ran a 3D seismic program.  One of the purposes of this program will be to identify natural fractures.  The horizontal wells are then run so that they intersect these fractures.  The multistage fracking then tries to tie the matrix - which is not naturally fractured - into this network of natural fractures and to the well bore.
