The Weight – Explaining the Bump in Heavier Crude Oil Production in Texas, New Mexico and North Dakota

By May 16, 2025No Comments

The Energy Information Administration (EIA) recently raised a few eyebrows across the energy industry with a report that producers in three key shale states — including Texas, the nation’s #1 oil producer — seem to be extracting larger amounts of “heavier” crude oil. Of course, the oil is only heavier relative to the light and superlight grades that have been produced in copious amounts since the dawn of the Shale Revolution. But these denser, lower-API volumes have recently helped drive growth in total crude output. In today’s RBN blog, we unpack what the EIA discussed in its writeup, explore some of the possible drivers behind the apparently heavier oil production, and discuss what it might mean for the domestic market.
