Received December 16, 1974. The work upon which this report is based was done under a cooperative agreement between the U.S. Energy Research and Development Administration, Laramie Energy Research Center, and the University of Wyoming. Reference to specific trade names or manufacturers does not imply endorsement by the U.S.E.R.D.A. Prior to completion of this work Laramie Energy Research Center was a unit of the U.S. Bureau of Mines.

The raw Colorado shale oil used in this study was provided by DOE s Laramie Energy Research Center (LERC). It was prepared in the Paraho tests in a surface retort operated in the so-called indirectly heated mode. As received, it was an emulsion containing 6% water and about 0.5% fine particles in the shale oil. Heating this mixture to 170°F broke the emulsion most of the water and fines settled out after standing at... 

X omestic tar sands are known to contain over 30 billion barrels of oil, - most of which occurs in a few deposits in Utah (I). The Laramie Energy Research Center (LERC) is investigating many of these deposits in order to determine the potential for exploitation of this resource. 

Late in 1975, personnel from Laramie Energy Research Center (LERC), then of the U.S. Energy Research and Development Administration, conducted an in situ recovery experiment in the Northwest Asphalt Ridge deposit near Vernal, Utah. Reverse combustion was chosen as a recovery method because it was felt that this method was more likely to succeed for in situ recovery of tar sands hydrocarbons. 

Work in the area of hydrocarbon-type analysis, i.e. saturate, olefin, and aromatic, has been conducted at the Laramie Energy Research Center (LERC) for over two decades. During this time, a significant portion of the eflFort has been directed towards the quantification and characterization of the various types of olefins found in Green River Formation shale oils and their distillate fractions (1-9). 

The authors are indebted to R. W. Sanders, M. R. Smith, J. H. Reeves, C. L. Nelson, and M. R. Grove for their assistance with the analyses. E. S. Getchell, R. M. Garcia, and G. M. Garnant provided assistance with preparation of the manuscript. We are also indebted to the staffs of the Laramie Energy Research Center, Lawrence Livermore Laboratory s Oil Shale Project, the Pittsburg and Midway Coal Company, and Phyllis Fox of the University of California, Berkeley, for providing us with samples. This research was supported by ERDA Contracts RPLS-2126 and RPLS-1654.

Similar class fractionation schemes coupling chemical extraction with short-term mutagenicity testing have been used with a variety of complex test materials. Other fractionation schemes applicable to synthetic oils have been developed by the Laramie Energy Research Center and Battelle Northwest Laboratories.
