Apparently Utah sits on a large reserve of tar sands, especially in the northeastern part of the state near Dinosaur National Monument. A Canadian company has leased about 32,000 acres to open a pit mine. The process would be similar to that in Alberta, Canada, but would be less water-intense and would not rely on strip-mining. Rather, it would rely on deep, salty groundwater (~2500 feet below the ground surface) and a relatively non-toxic compound called limonene to extract the oil. Water recycling in the pits would ensure that no wastewater ponds sit onsite and potentially harm local ecology. It does sound like an improvement on Alberta’s methods, but I have to admit that my ears perk up at the thought of mining tar sands in Utah. You should see the satellite image of the area north of Ft. McMurray in Alberta – that’s a massive mining operation. I’ve traveled a lot in southern Utah and appreciate its remote and inhospitable scenery. I start to feel like an environmentalist: “Protect the wilderness from all encroachment!!”
Sometimes, though, nature solves its own problems. There is very little rain or surface water in northeastern Utah, and apparently the aquifer 2500 feet below ground isn’t quite as productive as the mining company expected:
But records on file with the Utah Division of Water Rights hint U.S. Oil Sands may be struggling to find the deep water. The company drilled three dry wells before finding water somewhere between 2,000 and 2,500 feet in a fourth well, according to Dennis Sorensen, with the Utah Division of Water Rights. In June the company requested a drilling permit for a fifth well.
Ok, well, that will settle things, then, won’t it? Hard to get the oil off the sands if you don’t have any water. And drilling wells 2500 feet deep is expensive, not to mention pumping salty water out of those wells from those depths. I’d say that if this company figures out how to make profit with that water source and without contaminating the local area or strip mining, they’ll have fully earned their money.
