The Models of Estimating Oil Shale Flows and Price

The fast economical growth of Estonia in past years has set us several questions on sustainability of oil shale mining in Estonia. For how long do the oil shale resources last? What are the mining expenditures in the areas of different mining conditions and how do they change in future? Thus, in which districts is it feasible to mine? What is the optimum point of trade oil shale quality? The quality of oil shale and the future mining cost. Where is it feasible to mine at all? The useful component of oil shale is kerogen (organic matter). The main quality indicators of oil shale are calorific value and oil yield. Oil shale bed consists of oil shale layers altered b
