Can someone clarify the $ illustration? its the per daily barrel that is not clear?

 otherwise...very good article!

Estimates of Capital Expenditures for one of these conversion facilities are between $5,500 and $7,200 per daily barrel. An estimate of what it costs to convert a barrel of heavy oil to light oil is around $8.20. When you consider that there is almost an unlimited supply of heavy oil out there on the planet that isn't even being drilled, that $8 dollar a barrel figure is peanuts.
