About This Leaderboard

Source: Mississippi State Oil & Gas Board well-header records.

Ranking: Operators ranked by total well count under their current operator-of-record. Recent permits cover the last 24 months; DUC count is wells spudded but not yet producing; producing-well count is wells with a first-production date on file.

Why it matters: Knowing who operates the most wells in Mississippi — and who's drilling the most NOW — helps mineral owners understand who they're dealing with at the lease level.

Refresh cadence: Monthly. Data current as of 2026-08-02.
