Petrobras, Mitsui Sign Accord to Study Utah Oil-Shale (Update2)) but noted this excerpt. https://www.bloomberg.com/apps/news?pid=20601101&sid=a7GoYrjLZeE0&refer=japan
"Petrobras's oil-shale extraction process uses low temperatures, has no moving parts and produces far lower carbon emissions than making oil from other alternative sources such as coal, he said. Water isn't needed to operate or cool the process; it is a byproduct of their system, said Demarco Epifanio, the Petrobras International Unit executive responsible for the project.
``I have no doubt this will be a success,'' he said. ``Everyone else is selling an idea while we have a project that works.''
Expanding Output
Petrobras, which has been producing oil from shale commercially for 30 years in Brazil's Parana state, is seeking to expand oil output in the U.S. and other markets and to use its patented Petrosix processing technology to diversify the sources of oil, according to the statement.
The company only produces about 3,800 barrels of oil a day using its process in Brazil. If it's proven viable, the Utah project, which will receive $12 million for studies over the next 12 months, can produce much more, Epifanio said.
``Petrobras never does anything small,'' he said. ``In Brazil we developed this 30 years ago out of necessity. We didn't have many other sources of oil, but we have been developing and perfecting the technology since then and are looking for projects that would allow us to use it on a larger scale.''
