The spotlight often shines on the public E&Ps and major oil companies, while the private independent producers toil in the shadows. But no more. Oil and Gas Investor partnered with Drillinginfo Inc. to generate a ranking of private independents to show which ones—on a gross throughput at least—rise to the top in volumes produced. And not all of them, not most even, are old behemoths. Many of the names on our list are less than a decade old, illustrating how an entrepreneurial team with a plan, good assets and financial backing can rise to the top in short order.

The order of rank is based on publicly reported data of daily gross barrels of oil equivalent (boe) production, averaged over the trailing 12 months. Gas is converted 6 thousand cubic feet Mcf to 1 boe.

So which are the top 100 private U.S. E&Ps based on production? Read on to find out.
