“The hydrocarbons locked up in shale rocks in Colorado, Wyoming and Utah, known as kerogen, was again touted as the answer to America's energy problem.”
“Oil shale is sedimentary rock that contains solid bituminous materials -- called kerogen -- that are released as petroleum-like liquids when the rock is heated.”
“Traditionally, the shale has been surface mined like coal and heated until an oil-like substance called kerogen turns to liquid and oozes out.”
“Geologists estimate, and re-estimate, the Earth's carbon reservoir at more than 75 million billion metric tons, mostly buried in limestone, dolomite, ossified gunk called kerogen, coal, oil, and natural gas.”
“This is a sedimentary rock that contains a solid compound called kerogen, which can be refined into a synthetic crude oil.”
“When the oil shale gets to a suitable temperature, the hydrocarbon material - called kerogen - becomes a vapor.”
“Oil shale development involves extracting kerogen, a precursor to crude oil, out of the earth by first heating it to the point where it becomes liquid.”
