# Mississippi Mineral Rights: Complete Owner Guide

**TL;DR:** Mississippi is a mature oil-producing state dominated by CO2 EOR operations, primarily in southeast counties (Wayne, Jasper, Clarke, Jones). Denbury Onshore leads production with Jackson Dome CO2 floods, generating approximately 237,000 barrels monthly from the top 20 units. The state's primary producing formations include the Smackover, Lower Tuscaloosa Marine Shale, and Hosston Sandstone.

## Key Takeaways

- Mississippi produces ~237,000 barrels of oil per month from its top 20 producing units, concentrated in southeast counties
- Denbury Onshore operates 5 of the top-20 units, all utilizing Jackson Dome CO2 enhanced oil recovery floods
- Wayne County leads with 5 top-20 units including Eucutta East, Yellow Creek W/E, and Diamond fields
- The Smackover Formation is the dominant Jurassic carbonate producing interval across the state
- Out-of-state mineral owners can complete sales entirely remotely without traveling to Mississippi
- Jackson Dome's naturally occurring CO2 reservoir supplies the Northeast Jackson Dome (NEJD) pipeline system for EOR operations
- Major operators beyond Denbury include Highmark Energy, Tellus, Formentera, Venture, and Durango
- Mississippi's mature-field portfolio combines conventional production with emerging unconventional Lower Tuscaloosa Marine Shale potential

## Page Highlights

**Primary Producing Counties**: Wayne County dominates with 5 top-20 units, followed by Jasper (3 Denbury CO2 floods), Clarke (3 mature-field positions), and Jones (2 positions). Additional production comes from Yazoo, Lincoln, Lamar, Perry, Greene, and Adams counties.

**Key Producing Formations**: The Smackover Formation is the primary Jurassic carbonate target. The Lower Tuscaloosa Marine Shale represents emerging unconventional potential. Additional targets include Hosston Sandstone (Lower Cretaceous), Norphlet Sandstone (deep Jurassic gas near the coast), and Selma Chalk (Upper Cretaceous fractured chalk).

**Operator Landscape**: Denbury Onshore controls 5 top-20 units through Jackson Dome CO2 floods. Tellus Operating Group produces from Yellow Creek West and Baxterville. Highmark Energy operates Tinsley field, while Venture Oil & Gas manages Reedy Creek and Glazier.

**CO2 EOR Operations**: Mississippi's production heavily relies on carbon dioxide enhanced oil recovery using naturally occurring CO2 from Jackson Dome. The Northeast Jackson Dome pipeline delivers CO2 to multiple flood projects. ExxonMobil's acquisition of Denbury has implications for future operations, and 45Q tax credits affect sequestration economics.

**Inheritance and Legal Resources**: The page provides links to guides covering Mississippi mineral rights inheritance, affidavits of heirship, dormant mineral statutes, probate procedures, and recording requirements for mineral deeds.

**Selling Process**: Buckhead Energy purchases mineral rights and royalty interests across Mississippi's mature-field landscape, offering remote transaction capability for out-of-state owners and free written valuations incorporating Jackson Dome CO2 supply and operator strategy considerations.
