Publicly traded companies made up just 2% of roughly 12,000 U.S. oil and natural gas producers in 2025, yet they delivered 68% of Lower 48 crude oil and natural gas production, according to Enverus data.

The U.S. Energy Information Administration, citing Enverus, published the analysis this week. It shows a production base split between a handful of very large public operators and thousands of small private ones.

How concentrated is U.S. production?

The 12 firms with the most wells represent less than 1% of all producers. Each operates between 10,000 and more than 50,000 wells, and they average 39,000 barrels of oil equivalent per day per well.

At the other end of the distribution, 64% of all operators hold 10 or fewer wells — nearly all stripper wells producing less than 15 boe/d.

Why do public companies dominate output?

Enverus attributes the gap to three factors:

• Massive scale, which generates economies of scale that lower per-unit production costs
• Prime drilling locations, with higher-quality acreage yielding higher volumes
• Advanced technologies

Public companies generally report lower breakeven prices — the minimum price needed to cover operating costs — than privately held competitors. Higher-quality acreage holdings drive part of that advantage.

Where is the public share highest?

Of the five major producing regions in the Lower 48, Appalachia and the Permian show the largest public company share of production.

In Appalachia, in the northeastern United States, public companies produce nearly five times as much oil and natural gas as private companies while accounting for only 1% of active operators.

The Permian, spanning New Mexico and Texas, tells a similar story: public companies represent 3% of active operators yet collectively produce four times as much as private operators.

Where do private companies still lead?

The Haynesville, the natural gas-rich play straddling Texas and Louisiana, is the outlier. It is the only major U.S. producing region where private companies hold the majority of output, at 55%.

Even there, production concentrates among the largest private players. The top five private natural gas operators produced 38% of the region's gas output, equivalent to 5.8 billion cubic feet per day. The top five private crude producers accounted for 30% of Haynesville oil production, or 10,000 barrels per day.

What's the watch item?

The concentration figures frame how consolidation and high-grade acreage control respond to price cycles. As operators weigh 2026 capital plans against gas demand growth from LNG exports and the next OPEC+ supply decision, the breakeven advantage held by large public producers — and the Haynesville's private gas majors — will determine where marginal barrels and cubic feet come from.
