Figure 20.26 Peak oil curve. The concept of peak oil revolves around the notion that we may be reaching global peak oil production. The
subdivisions of the graph represent the contributions of specific geographical regions to the overall global oil supply over time. NGL refers
to natural gas liquids, whereas heavy supplies are those that do not flow easily and have thus been previously ignored. If this scenario is
accurate, note the progressive drop in global oil supplies in the coming decades.

Figure 20.27 Geography of uncon-
ventional oil and gas deposits in
North America. The Athabasca oil
sands are believed to contain 178 bil-
lion barrels of oil, which is currently in a
semi-solid form called bitumen. Uncon-
ventional deposits in the United States
are mostly associated with extensive
shale deposits scattered around the
country. Although most of these plays
are largely known for their gas depos-
its, several contain abundant supplies
of shale oil.
