The Permian Basin served as the primary engine for this expansion. Texas output climbed to 5.83 million barrels per day, while New Mexico reached a new peak of 2.37 million. North Dakota also contributed to the surge, hitting 1.13 million barrels per day, its strongest performance since November. These monthly figures validate earlier weekly estimates that analysts had previously treated as potential statistical noise.

Energy Information Administration data confirms that the industry's agility significantly outpaced official forecasts. The April output exceeded the agency’s own 2026 projections by over 200,000 barrels per day. While global oil prices have since retreated following a ceasefire in the Persian Gulf, the data underscores how rapidly domestic supply reacts to sudden price incentives. Although tanker traffic remains below pre-war levels, the record production suggests a structural shift in U.S. capacity that materialized during the height of the regional crisis.
