Mineral Rights in Mississippi: The Law

The regulator: Mississippi State Oil and Gas Board

The State Oil and Gas Board permits Mississippi wells, approves enhanced-recovery and horizontal rate reductions, and publishes the production records we check on every Mississippi evaluation. MSOGB.

Mississippi has no dormant mineral act

A severed Mississippi mineral interest does not lapse for non-use, and the legislature has repeatedly declined to change that. A 2024 bill to revert mineral estates to the surface owner after ten years of non-production died in committee, as did identical predecessors in 2013 and 2021. Mississippi also has no marketable record title act — a 2019 bill died in committee and in any event carved out mineral interests. Do not confuse this with the statute allowing cancellation of the record of an expired lease, which is a record-clearing tool, or with unclaimed property law, which escheats undelivered proceeds rather than the mineral estate.

Producing minerals are exempt from all ad valorem tax

Mississippi statute exempts all oil and gas produced, all leases in production including mineral rights in producing properties, and all oil or gas under the ground on producing properties from every state, county, municipal, levee, road, school, and other district ad valorem tax — and provides that no additional assessment may be added to the surface value because oil lies beneath it. A parallel provision covers gas and carbon dioxide. Do not carry Texas-style annual county mineral assessment expectations into Mississippi.

Section-township-range — across five meridians

Mississippi is a rectangular-survey state but is governed by more principal meridians than any other, which is a real source of title error: the Choctaw Meridian near Jackson, the Chickasaw Meridian in north Mississippi, the Washington Meridian in the southwestern Natchez district, and the St. Stephens Meridian in the Pearl River district. Drilling units are described in aliquot terms — the regular governmental quarter-quarter section for oil, the regular governmental half section for gas. Irregular metes-and-bounds tracts exist inside the Washington Meridian net where Spanish and British private land claims were confirmed as numbered irregular tracts.

Where oil and gas is produced in Mississippi

Oil and gas activity in Mississippi is concentrated in these plays and basins:

• Mississippi Interior Salt Basin — Southwest and south-central Mississippi — the dominant province, with Lower Tuscaloosa by far the most common producing formation, plus Smackover, Hosston, Cotton Valley, and Wilcox.
• Smackover trend — Upper Jurassic carbonate production across the Interior Salt Basin — Tinsley in Yazoo County, Loring in Madison, Bienville Forrest in Smith.
• Selma Chalk — The Rankin and Hinds county gas engine, including the Jackson Field, extending into Madison and Yazoo.
• Tuscaloosa Marine Shale — Extends into the southwest corner — Amite, Pike, and Wilkinson counties — with limited activity since 2016.

What this means for Mississippi mineral owners

The facts above — who regulates, whether an idle interest can lapse, how production is taxed, and how land is described — are the Mississippi-specific rules that shape what you own and how it is protected. For the doctrines behind them see oil and gas law and the rule of capture; to compare states, see mineral rights by state. Buckhead Energy buys Mississippi mineral and royalty interests and prices them on the same regulator and production records described here. This is educational background, not legal advice; Mississippi oil and gas law is fact-specific, so consult a qualified Mississippi attorney about your interest.
