Exxon reportedly eyeing oil-shale work on W. Slope

Exxon Mobil could use its long-idle Colony Project site to begin new research into extracting oil from shale, government regulators and industry experts say.

News of the possible revival at the site comes nearly 25 years after Exxon Mobil predecessor Exxon Corp. shut down its oil-shale research at the Colony Project and threw thousands of western Colorado residents out of work. May 2, 1982, became known as “Black Sunday.”
