The Promise and Peril of Shale Oil On a 160 acre parcel near Meeker, Colorado, Shell Energy Corporation is trying to efficiently extract the hydrocarbons from a layer of rock known as the Mahogany Shale. It's been tried before, many times, dating back to when cowboys noticed that if you used certain dark rocks in your fire ring, they'd catch fire. But Shell is taking the effort to a new level, spurred by record energy prices, accommodating federal land managers, and a willingness to radically evolve the technologies for extracting fossil energy from the earth. It will take ten to fifteen years to discover if the experiment will produce economically viable amounts of oil and natural gas, or if the EROEI – the energy returned on energy invested- will balance out, but the technologies involved in the experiment are so new that in the course of operations, some entirely different process may yet reveal itself, drawing the elusive genie of energy from the thousands of square miles of ancient seabed algae....
