Analysis: U.S. Oil Output Beat Estimates on Efficiency Gains

VIENNA (DTN) – U.S. crude production hit record highs in June, defying falling rig counts as better extraction technology at drilled but uncompleted wells helped the world’s largest oil producer retain its supremacy.

Crude output reached an all-time high of 13.58 million bpd in June, monthly data from the U.S. Energy Information Administration showed. Weekly EIA data had pegged U.S. crude oil production at 13.422 million bpd in June, undershooting the final number by 158,000 bpd. The underestimate was a function of weekly data in the second quarter, which suggested relatively unchanged output that flipped the agency’s previous tendency of overestimating production.

Accompanying data released by the EIA showed that efficiency gains and the use of drilled but uncompleted wells, known as DUCs, had counteracted the falling number of active rigs.

In June, the average rig produced 25,400 bpd, compared to 23,700 bpd in June of 2024. At the same time, the number of DUCs continued to decline, reaching a new low of 5,325 in June. Since then, the number of active rigs and DUCs has fallen further, with a record-low 520 active rigs in August and 5,215 drilled but uncompleted wells remaining.

Monthly data now reveal continuous steady growth in crude output despite falling rig counts. In the first six months of the year, U.S. field production increased by 440,000 bpd, up 328,000 bpd, or 2.5%, year-on-year.

Distillate fuel oil inventories have been historically tight this year, despite weekly data suggesting only a marginal uptick in demand compared to 2024. The EIA’s Petroleum Supply Monthly for June showed significantly higher diesel consumption and revealed a growing gap between weekly estimates and monthly figures.

Distillate fuel oil supplied, a proxy measure for demand, averaged 3.965 million bpd in June, up 302,000 bpd, or 8.2%, year-on-year. This was some 240,000 bpd, or 6.4%, higher than suggested by weekly data. The EIA had underestimated demand in April and May by 175,000 bpd and 231,000 bpd, respectively.

Monthly data also showed that in the second quarter of 2025, distillate fuel oil supplied outpaced year-ago levels by some 137,000 bpd. While some may read this as a sign of improved economic conditions, a sizable chunk of this increase was likely caused by importers trying to fill their inventories ahead of the large-scale implementation of tariffs, leading to more trucking demand.

If companies front-running freight operations were indeed the main culprit of improved diesel demand, it is likely that distillate fuel oil consumption will eventually ease back

closer to year-ago levels. This makes the recent jump in demand a more nuanced indicator than a straightforward economic signal.
