Onshore crude oil production in the U.S. Lower 48 states (L48) has more than tripled since January 2010, driven by tight oil production growth in the Permian region. Onshore crude oil production is made up of both legacy oil production, primarily from vertically drilled wells, and newer tight oil production, primarily from horizontally drilled wells.
