Future of petroleum production


Consumption in the twentieth century has been abundantly pushed by automobile growth; the 1985-2003 oil glut even fuelled the sales of low economy vehicles in OECD countries. In 2008, the economic crisis seems to have some impact on the sales of such vehicles; still, the 2008 oil consumption shows a small increase. The BRIC countries might also kick in, as China briefly was the first automobile market in December 2009. The immediate outlook still hints upwards. In the long term, uncertainties linger; the OPEC believes that the OECD countries will push low consumption policies at some point in the future; when that happens, it will definitely curb the oil sales, and both OPEC and EIA kept lowering their 2020 consumption estimates during the past 5 years. Oil products are more and more in competition with alternative sources, mainly coal and natural gas, both cheaper sources.
In terms of alternatives to oil, natural gas is the cleanest burning fossil fuel; it is also abundant and affordable. In terms of potential future developments, many gas and oil companies are considering the economic and environmental benefits of Floating Liquefied Natural Gas (FLNG). This is an innovative technology designed to enable the development of offshore gas resources that would otherwise remain untapped, because environmental or economic factors make it unviable to develop them via a land-based LNG operation. The only FLNG facility currently in development is being built by Shell, due for completion in around 2017.
Production will also face an increasingly complex situation; while OPEC countries still have large reserves at low production prices, newly found reservoirs often lead to higher prices; offshore giants such as Tupi, Guara and Tiber demand high investments and ever-increasing technological abilities. Subsalt reservoirs such as Tupi were unknown in the twentieth century, mainly because the industry was unable to probe them.Enhanced Oil Recovery (EOR) techniques (example: DaQing, China  ) will continue to play a major role in increasing the world's recoverable oil.

Hubbert peak theory

The Hubbert peak theory (also known as peak oil) posits that future petroleum production (whether for individual oil wells, entire oil fields, whole countries, or worldwide production) will eventually peak and then decline at a similar rate to the rate of increase before the peak as these reserves are exhausted. The peak of oil discoveries was in 1965, and oil production per year has surpassed oil discoveries every year since 1980.
Hubbert applied his theory to predict the peak of U.S. oil production at a date between 1966 and 1970. This prediction was based on data available at the time of his publication in 1956. In the same paper, Hubbert predicts world peak oil in "half a century" after his publication, which would be 2006.
It is difficult to predict the oil peak in any given region, due to the lack of knowledge and/or transparency in accounting of global oil reserves. The scientist and researchers from Oxford University argue that official figures are inflated because OPEC members over-reported reserves in the 1980s when competing for global market share. Based on available production data, proponents have previously predicted the peak for the world to be in years 1989, 1995, or 1995-2000. Some of these predictions date from before the recession of the early 1980s, and the consequent reduction in global consumption, the effect of which was to delay the date of any peak by several years. Just as the 1971 U.S. peak in oil production was only clearly recognized after the fact, a peak in world production will be difficult to discern until production clearly drops off.
The International Energy Agency (IEA) says production of conventional crude oil peaked in 2006. Since virtually all economic sectors rely heavily on petroleum, peak oil could lead to a "partial or complete failure of markets."
