You sound like a poster who knows a thing or two about the oil business. Since through three of your posts, and I haven't read down very far, there has been no mention of the
quality of your tar sands crude, perhaps we should start there. It's not Brent sweet light crude, it's not West Texas Intermediate, shit, it's fucking bitumen. It's great for asphault, roofing shingles, and sealing your canoe per the First Canadians first use.
The shit's dirty. If we needed fuel to escape orbit to avoid imminent planetary disaster, and we've squandered our other options, maybe, but damn, just on the outside chance the climate change scientists are correct in their hypothesis... right?
