Another aide, Jim Seymour, explained that at the present level of technology, there will be no hope of exploiting the rich tar sands of Alberta to such a degree that the Canadian federal government would allow exports to flow once again...
...tar balls were the first debris to hit U.S. waters from the runaway Mexican oil well that has dumped 265,000 tons of oil into the Gulf of Mexico, causing one of the biggest oil spills in history-and potentially a major environmental disaster...
Mexican beaches were the first to be hit. They were spotted last week with giant puddles of crude oil and thick clusters of tar balls. The Mexican government mounted an emergency airlift to carry newly hatched Atlantic ridley turtles, an endangered species of giant sea turtle, from the polluted beaches...
...contrast, the accumulation on South Padre Island's spectacular beach was not much heavier last week than usual: bits of tar routinely float in from passing tankers. Bathers have got used to oil-stained feet. Thus few cancellations were reported at hotels. Padre Island, a thin barrier reef that stretches approximately 130 miles north from its highly developed southern tip, was slightly harder hit. But the oil was still no worse than a thick line of tar at the water's edge...
Though the U.S. has some oil-saturated tar sands, they are not large or accessible enough to justify expensive exploitation by the Government. But some 76 billion bbl. in oil, about three times the nation's proven reserves of conventional crude, are known to be recoverable from the shale rock concentrated in western Colorado and stretching into Utah and Wyoming. No plants are in operation at present, but at least five companies are running experimental digs in the area. To produce a barrel of oil, about 1½ tons of rock must be mined and heated...
