✦ Synopsis

A rapid and practical test for oil-shale richness is of considerable technical importance. Although the Fischer-Schrader method has gained universal acceptance for determination of shale richness, there is need to relate results from this determination to fundamental parameters of the shale. One much-used relation is with elemental analysis, and numerous equations have been derived to correlate shale richness with organic carbon content. These relations have been reviewed, and from a number of intensively analysed samples selected from a coring in the Parachute Creek member of the Green River Formation equations relating oil yield by Fischer-Schrader determination to organic carbon content have been developedt: oil (wt %I = 0.8317(%&,,,) -02509 and oil (gal/ton) = 2.216(%C,r,) -0.7714

Additionally, more detailed knowledge of the uniformity of organic material throughout the Green River Formation was obtained. It was found that the fraction of kerogen which on pyrolysis yields liquid products is constant stratigraphically throughout the formation, even though the oil composition is not.
