RE: fractures OilEng
I'm not a reservoir geologist or engineer either. So I defer to your experience.
But I recall that natural geologic conditions to generate economic deposits of oil and gas depend on when maturation occurs, if host and reservoir formations are present and when deformation occurs. I'll see if I remember this correctly: Natural pressure within the source rock formation develops by the maturation of kerogen and the developing hydrocarbons are released to the source rock formation, the gas is released more rapidly than the oil (depending on the nature and type of kerogen (or source deposit in the case of coal gas/no oil) due to lower viscosity. If extensive fracturing is present, free gas is produced and eventually the pressure source to drive the oil to the fractures is depleted. Also, depending on the stratigraphy and condition of overlying stratigraphic (trapping) conditions, the gas and oil may migrate (or in the absense of trapping conditions) the migrating hydrocarbons maybe lost to more permeable formations that could result in uneconomic accumulations.
Husky drilled into a sizeable zone that was a drillers nightmare ...could the formation(s) be so badly deformed the released hydrocarbons were never trapped or lost to subsequent migration? I believe an analogy would be hydrocarbon seeps at surface.
