Obama is the Keystone Cops, going over a cliff and still never getting his "man".
Poor old "heavy crude" sometimes called "bitumen", it's not as fast flowing as "light, sweet crude", so it's called "dirty". Alberta oil sands have been a huge target of foreign funded attacks by our stupid, greedy "greens".
Interesting to know, Alberta is not the only producer of "heavy crude", even though you wouldn't know it from our far left media/environmentalists.
Increasing U.S. Dependency on Foreign Crude Oil
Over the past five years, studies of global oil production have consistently predicted that diminishing discoveries of conventional crude oil will cause worldwide oil production to peak and irreversibly decline by the end of the present decade., , , ,  But heavy hydrocarbons still remain as a largely untapped petroleum resource — heavy crude oil and natural bitumen (also called “tar sands” or “oil sands”) exist in abundance.
Heavy oil was discovered in California before the turn of the previous century and currently comprises about half of the state’s crude oil production. With this production spread among more than 200 reservoirs, significant infrastructure to access heavy oil is already in place.
Foreign interests are sponsoring Canadian environmental groups to stop the Gateway pipeline. WHY? What's in it for them, except control of our oil without investment in it?
Even the middle east realizes that "heavy crude" has to be looked at.
Middle East oil countries should increase production of heavy oil as oil prices remain higher and improved technology makes it easier, those attending an industry conference in Bahrain were told.....
Production and refining of heavy crude costs more than recovering and processing light crude. Production of heavy oil from oil sands in Canada’s Alberta province has an estimated break-even point of $35 a barrel, Mirza noted. But Bahrain’s heavy oil could be recovered at a cost of between $8 and $9 a barrel, he said.Hello environmentalists, the gig is up. You should go to the middle east and tell them that they need the same environmental controls as Canada has had imposed on them. But they won't because environmentalists are chicken little's, running around in circles, wearing polar bear suits, yelling that the sky is falling, the sky is falling!
Oil prices in recent weeks have fluctuated in a range of $70 to $80 a barrel, which OPEC officials have declared an ideal range.
“Heavy oil will be a savior to the ever-increasing demand for fossil fuels from the developing nations,” Mirza was quoted as saying.
