Abstract Drill cores from 18 exploratory holes that were drilled into the unleached saline beds were tested for mechanical properties. Test cores were primarily selected from zones L4B, R4B, L3, and R3A. Regression analysis techniques were tried in an attempt to relate kerogen yield or apparent specific gravity to the parameters compressive strength, Young's modulus, and Poisson's ratio. Correlation coefficients were very poor, indicating that this type of analysis was not amenable to these data. Analysis of variance techniques were tried using a division of greater or less than 10% nahcolite together with the requirement of less than 3% dawsonite. Results showed that a larger percentage of nahcolite tended to lower the compressive strength and to increase Young's modulus. A second analysis was made using a division of less than 3% dawsonite and greater than 3% dawsonite together with the requirement of less than 1% nahcolite. For this analysis, a larger percentage of dawsonite tended to increase compressive strength, Young's modulus, and Poisson's ratio.
