Many countries have negligible coal reserves. The United States, Russia, and China contain the largest percentage of global coal reserves. Major coal regions in the United States are outlined in Figure 2-8. Lignite and anthracite are found predominantly in the Gulf Coast (Texas) and Northern Great Plains (North Dakota, South Dakota, and eastern Montana) regions. Sub-bituminous coal is located in the Rocky Mountain region. Bituminous coal is located in central Texas, central Colorado and Utah, the Interior region of Illinois, Missouri, and Iowa, and the Eastern region stretching from Alabama to Pennsylvania.
The composition of the highest rank coal, graphite, approaches 100% carbon. Coal becomes darker and denser with increasing rank. Coals burn better if they are relatively rich in hydrogen; this includes lower rank coals with higher hydrogen to carbon ratios. The percentage of volatile materials in the coal decreases as coal matures. Volatile materials include water, carbon dioxide and methane. Coal gas is gas absorbed in the coal structure or coal matrix. It is primarily methane with lesser amounts of carbon dioxide.
Unconventional oil refers to hydrocarbon production from low permeability shale (shale oil) and tar sands. Unconventional gas refers to gas production from coal (coal gas), low permeability sands (tight gas), and low permeability shale (shale gas). The primary difference between conventional and unconventional oil and gas is the ability of the fluid to flow through rock. The objective of this chapter is to describe how oil and gas resources are formed and distributed throughout the world. We begin by discussing the geologic environment.
