What is the "shale revolution"?

Deciphering the shale revolution: how shale oil has redefined the global energy landscape.

Since its emergence, shale oil has radically transformed the global energy market, propelling the United States to the rank of the world's leading oil producer. This revolution, which began in the 2010s, has led to an unprecedented expansion in US oil production, doubling between 2011 and 2014 thanks to the exploitation of unconventional sources.

From 2011 to 2014, U.S. oil production doubled, due to the start-up of production from non-conventional oil.

NB: the drop visible at the end of the chart in 2015 was temporary (see next chart).

US oil production doubled between 2008 and 2014.

Since 2018, the United States has (re)become the world's leading oil producer.

The US also became a net oil exporter again in 2018 (the export embargo was lifted in 2015).

Note the scale: the graph does not start at zero.

Since 2005, global production of so-called "conventional" oil has been on something of a plateau.

Since then, growth in world production has come from "unconventional" oil.

Shale oil is the main unconventional oil.

The geopolitical consequences of the "shale revolution" are enormous: energy self-sufficiency for the United States is a powerful factor in justifying a policy of non-intervention, or even withdrawal, on the international stage.

Unconventional" deposits are small and of little interest to the world's major oil companies. The shale revolution is being led by small oil companies, the "independent producers", often heavily in debt.
