“…Such an extrapolation is based on the assumption that the relationship a = K/pC (1) (where a = thermal diffusivity, p = density and C = the heat capacity of the material) holds good for oil shales in general. The good correlation which was previously observed (Wang et al, 1979a) between K values calculated from eq 1 and those measured directly by experiment indicates that this may well be the case. Considerable interest has long existed in novel organic substances which offer advantageous use as plasticizers, binders, or burn modifiers in solid explosive or propellant compositions.…”

A comparison of the functional dependence of thermal conductivity (K) on temperature and organic content, Is presented for the oil shales of Colorado, Utah, and Wyoming. Data are presented for the thermal conductivities of Utah shales with oil yields ranging from 28 to 312 liters per ton (L/t). The K values for these samples span a decade from 0.3 to 3.0 W nr1 deg"1 depending on the amount of organic matter in the shale. Retorting brings about a substantial decrease in K\ the values for the retorted shales falling in the range 0.2-2.0 W nr1 deg"1.The thermal conductivities of Wyoming oil shales vary from 0.7 to 1.3 W m~rdeg"1 for oil yields between 152 and 68 L/t, respectively. The Kvalues for Utah oil shales are in general higher than those corresponding to their Colorado and Wyoming counterparts-the differences being particularly more pronounced at low levels of organic content. The importance of mineral composition in determining the magnitude of K is discussed in this regard.

The dependence of thermophysical properties such as thermal conductivity, thermal diffusivity, specific heat, and dielectric constant on organic content is discussed for oil shales of the Green River Formation. The applicability of thermophysical measurements for assaying and retort diagnostic purposes is also discussed in the light of methods that are currently in use in oil shale science and technology.
