Ya,
Didn't pick up the word " heavy oil" in their written presentation, only " higher density", unless it was uttered verbally in a conference call or such. My definition of heavy would be less than 20 API, although I suppose this would be open to Sulfur/ viscosity etc.
My understanding also is that heavy oil is a result of water inundation, evaporation or bacteria breaking down what was once light crude. Obviously that particular interval of higher density oil was compromised somewhat, although no oil/ water contact was encountered.
It is also postulated that heavy oil is usually found on the margins of the basin structure. Hence, if that were to hold here, then lower Bell probably represents the limit of the northern extremity of SNE.
Your thoughts, if any?
Cheers
