The US crude oil market is undergoing enormous change with production exceeding forecasted levels. The US is now the second largest liquids producer in the world, and within a hair’s breadth of Russian output if one combines crude oil production with natural gas liquids and ethanol output. Light sweet crude imports into the US are vestigial as US refiners switch to the newly found streams pouring into the refining centers. Extensive exploration and production activity in crude oil shale plays such as Eagle Ford and Bakken has boosted domestic crude output for these new light sweet crudes. Hydraulic fracturing has also resurrected drilling activity in established plays such as the Permian Basin, the production center for WTI. This increased production, which has crossed the 800,000 b/d level for Bakken, 1.3 million b/d for Permian and above 800,000 b/d for Eagle Ford, has fundamentally altered wider crude oil dynamics in the US, including a significant impact on benchmark WTI.
