The economics of mining and processing the deep, thick oil shale deposits of the central Piceance Creek Basin is examined using a modified risk analysis computer program. The oil shale deposits in the Central Basin are at an average depth of 1,000 feet below the surface and occur in alternating sedimentary layers up to 2,000 feet thick. Several mining techniques are evaluated and costed for data input into the analysis. Processing plant capital investment and operating costs are modified from published technical reports. The input variables are defined as parametric and nonparametric probability distributions. Also included in the analysis are depletion allowance, federal tax, state and local taxes, royalties, and lease payments.
