The combined additional, unrestricted liquid production from the aggregate shale/tight oil formations examined in this paper could reach 6.6 mbd by 2020, in addition to another 1 mbd of new conventional production. However, there remain obstacles that could significantly reduce the U.S. shale output: among them, the inadequate U.S. oil transportation system, the country’s refining structure, the amount of associated natural gas produced with shale oil, and environmental doubts about hydraulic fracturing, one of the key technologies for extracting oil from shale. After considering risk factors and the depletion of currently producing oilfields, the U.S. could see its production capacity increase by 3.5 mbd. Thus, the U.S. could produce 11.6 mbd of crude oil and NGLs by 2020, making the country the second largest oil producer in the world after Saudi Arabia. Adding biofuels to this figure, the overall U.S. liquid capacity could exceed 13 mbd, representing about 65 percent of its current consumption.
The analysis in this paper is subject to a significant margin of error, depending on several circumstances that extend beyond the risks in each project or country. In particular, a new worldwide recession, a drastic retraction of the Chinese economy, or a sudden resolution of the major political tensions affecting a big oil producer could trigger a major downturn or even a collapse of the price of oil, i.e. a fall of oil prices below $70 per barrel (Brent crude).
Conversely, if an oil price collapse were to occur after 2015, a prolonged phase of overproduction could take place, because production capacity would have already expanded and production costs would have decreased as expected, unless oil demand were to grow at a sustained yearly rate of at least 1.6 percent for the entire decade.
The opposite could also happen. A sudden rebound of the world economy could strain the equilibrium of oil demand and supply, particularly if accompanied by geopolitical tensions.
A new world-wide economic recession, a drastic change in Chinese consumption patterns, or a sudden solution to major political tensions affecting a major oil producer (such as Iran), could trigger a major decrease and even a collapse of the price of oil. By collapse, I mean a fall below $50 per barrel for one year.
