Total domestic crude oil production recently pushed past the rest of the world’s crude oil production, according to the Energy Information Administration (EIA). The agency said March 26 that the jump in the U.S.’ supply volume is due to its strong production of tight oil.

In fourth-quarter 2013, overall domestic crude oil production averaged 7.84 million barrels per day (MMbbl/d), the agency said, due to the 3.22 MMbbl/d of tight oil that were produced.

That 3.22 MMbbl/d of tight oil pushed the country’s overall crude production past the rest of the world’s 10%, which had been just 9% in fourth-quarter 2012, the EIA said.

The U.S. and Canada are the only major tight oil producers, the agency noted, adding that North America has developed technologically-advanced drilling and completions processes.

This February, 63% of domestic tight oil came from the Eagle Ford and Bakken Shales, the EIA said. Of this number, 36%--1.21 MMbbl/d—came from the Eagle Ford, and 28%--0.94 MMbbl/d—came from the Bakken, the agency added.

In North America, 91% of all tight oil production is U.S.-based, and the remaining 9% is Canada-based, the agency said.

Canada’s tight oil production averaged 0.34 MMbbl/d last year, and came from Alberta, Manitoba and Saskatchewan. In the same year, Russia, the only other country producing commercial quantities of tight oil, produced 0.12 MMbbl/d from the West Siberia Basin, the EIA noted.
