A comprehensive guide to Mississippi mineral rights — counties, formations, operators, CO2 EOR, inheritance, and selling guidance.
Quick answer
Mississippi is one of the most consequential mature-field oil-producing states in the United States. The state's mature/EOR field portfolio — concentrated in southeast Mississippi (Wayne, Jasper, Clarke, Jones counties) plus selected positions across south Mississippi — produces approximately 237,000 barrels of oil per month from the top 20 producing units. Most of the state's heavyweight production comes from Denbury Onshore Jackson Dome CO2 EOR floods, with Highmark Energy Operating, Tellus, Formentera, Venture, Durango, and other operators rounding out the operator landscape.
