One source is oil sands. In the past, obtaining enough usable oil from the mixture had been expensive but the $70 cost per barrel of crude oil has now made processing oil sands commercially viable. Engineers and geologists estimate there's enough oil in the oil sands in the province of Alberta to rival Saudi Arabia's oil reserves. The biggest hurdle faced by the Canadian oil producers is finding enough staff to move to the remote regions where the oil sands are located. Says Neil Camarta, senior vice president of Petro-Canada, "we're a huge reservoir of oil. The limits are (finding) the people."
