US domestic crude oil production has exceeded oil imports for the first time since 1995, according to the Energy Information Administration (EIA).
The EIA said petroleum imports were at their lowest since 1991, partially due to surging domestic oil production from hydraulic fracturing, or fracking.
In October, US crude oil output averaged at 7.7 million barrels per day (bpd).
The EIA says it expects output to exceed 8.8 million bpd by 2014.
The domestic oil boom has been due mostly to fracking, a new technique used to get oil from shale deposits in locations like North Dakota and Texas.
The technology has come under fire by critics concerned about the environmental impacts of the procedure.
The EIA says imports now make up 40% of US oil consumption – significantly less than the 60% peak reached in 2005.
