I onl,l unlaoa I t' I ' f xtracting oil from shale has always E b""n-"t best-an expensive, risky proposition. Even now, as oil shale gradu- ally lumbers toward commercial produc- tion, some doubs linger about whether or not producing oil from shale will prove profitable, particularly in light of today's economics. But at Paraho Development CorP. in Technology Base Crand Junction, CO, no such unce(ainties seem to exist, and managers of the small company (approximately 100 employees), bustle with enthusiasm for the oil shale industry in general and Paraho in particu- lar. Paraho has doubled the number of employees in the past year, and if all goes as planned, could have 1,500-2,000 employ- ees by 1986. Those plans include a pro- posed commercial oil shale faciliry the Paraho-Ute project, 50 miles southeast of Vernal, UT, as well as continued expansion of the company's research and technology, including maintaining the facility at Anvil Points, near Rifle, CO. Back to the Poinb In fact, Paraho's history is firmly an- chored to Anvil Points, where the U.S. Navy holds shale lands known as Naval Re- serves One and Three. During the 1940s and 1950s, the federal government, primar- ily through the U.S. Bureau of Mines, con- ducted research on oil shale mining and processing at the site, and the knowledge gained in those years has served as a basis for much of the shale technology used today. John B. Jones, Jr., a chemical en- gineer, was one of the researchers who worked on the project and helped develop the Bureau of Mines retort, a vessel in which crushed shale is heated to remove the oil. When the government program was discontinued in the 1950s, Jones and Rus- sell Cameron, who also worked on the project, formed their own engineering firm, Cameron and .lones. The company con- tinued to research oil shale and was in- volved in developing the Petrosix retorting process that is now being used in Brazil. The firm of Cameron and Jones was dis- solved in 1965, and Jones went on to form his own company, Development Engineer- ing, Inc. After he became self-employed, Jones Paraho's Anvil Points oil shale facility near Rifle, CO. co.invented a new retorting method that { Shale Counrr* Fehuary/March 1982 was based on the one devised at Anvil retort.
