The new knowledge generated here is expected to advance the understanding of the microstructural heterogeneity and mechanical property anisotropy in different types of shales.Burnt oil shale is produced from shales with 5%-65% organic matter. It is produced by the combustion of oil shales in bottom or fluidized bed furnaces used for steam or electricity generation. The resulting ash is of highly variable composition, depending on the make-up of the original shale and the temperature at which it is produced.Clay Mineral Composition. From the analysis of the composition of clay minerals (Table 1; Figure 2C), the average contents of mixed-layer illite/smectite (I/S) (46.62%) and illite (49.26%) of all the shales were found to be high, while there are also great differences among the shales from different sections.

Shale gas is an unconventional natural gas that is found trapped within shale formations. [1] Since the 1990s a combination of horizontal drilling and hydraulic fracturing has made large volumes of shale gas more economical to produce, and some analysts expect that shale gas will greatly expand worldwide energy supply.
