To simplify the description of a shale reservoir that has irregularly shaped matrix and microfractures, it is assumed that the matrix element is a sphere with radius R m; each matrix element is composed of organics and clay grains, and gas flow in matrix is only diffusion (shown in Fig. 1.23).

Sandstone is a sedimentary rock composed mostly of quartz sand, but it can also contain significant amounts of feldspar, and sometimes silt and clay. Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone.

The Burgess Shale refers to a fossil-rich locality on Fossil Ridge between Wapta Mountain and Mount Field, just a few kilometres north of the small town of Field, British Columbia.

Shale is the most common sedimentary rock, which accounts for about 70 …Shale Uses. Shale is an economically precious rock. Its mining and processing are usually very costly, but the products are worth the investment. Black shales (rich in unoxidized carbon) are an important source of rock for oil and natural gas. The organic material inside the rock was transformed into oil and gas when the rock was buried.Black shale, variety of shale that contains abundant organic matter, pyrite, and sometimes carbonate nodules or layers and, in some locations, concentrations of copper, nickel, …
