samclem,
Gee. I seem to remember that Syncrude and Suncore can make money down to $15/barrel. Shell just 'raised the bar' by paying more per barrel for an oil sands asset than anyone else ever had.
DON"T follow the technologies. Find a well-run oil company by checking are they replacing the barrels they produce with new barrels discovered. And check their balance sheets. In the past 20 years, several previously well-run oil companies have dug themselves into a hole. Shell got into trouble a couple of years ago by reporting their reserves on the generous side. Not quite Enron, but a couple of big guys got sacked.
Don't pay too much for an asset and don't buy the hype. I just saw a special on the Bronfmans and how the grandson of the old man lost the family $6 billion US.
