The peak of increasing oil supply, according to the International Energy Agency (IEA), will happen some time around the 2020 to 2030. This could increase the demand for oil extracting companies and peripheral technology that can find oil in more difficult locations. The manufacturing of oil from coal and natural gas is a potential benefit of a peak in oil supply.

This peak in demand will benefit countries with lots of untapped oil, such as Brazil and Saudi Arabia. The importance of oil will only grow over time. Sources of unconventional oil will also benefit as the demand for these more expensive sources increases. … "Peak Oil Supply" has a significant impact, so an analyst should put more weight into it.
