Mineral Rights in Indiana: The Law

Mineral rights in Indiana are governed by Indiana property and oil and gas law and regulated by the Indiana Department of Natural Resources, Division of Oil and Gas (IDNR). Whether a severed interest can lapse from non-use, how oil and gas production is taxed, and how land is legally described all follow Indiana-specific rules — set out below with the Indiana authorities that govern them.

Indiana extinguishes an unused interest after 20 years — automatically

Indiana Code § 32-23-10-2 provides that “an interest in coal, oil and gas, and other minerals, if unused for a period of twenty (20) years, is extinguished and the ownership reverts to the owner of the interest out of which” it was carved — unless a statement of claim is filed. The lapse is self-executing: no lawsuit and no individual notice is required, and the U.S. Supreme Court upheld exactly this design in Texaco, Inc. v. Short (1982), holding that publication of the statute itself is constitutionally adequate notice. "Use" is defined broadly — production, injection or storage operations, rentals or royalties paid, operations on a pooled or unitized tract, and payment of taxes on the mineral interest by its owner. Because Indiana already assesses producing interests as real property, an owner who simply pays the county mineral tax bill each year is continuously resetting the clock. (See IC 32-23-10-2.)

Indiana takes the greater of 1% or a flat per-unit amount

The petroleum severance tax is computed both ways per return, and you owe the higher. At any oil price above roughly $24 a barrel or gas above about $3.00 per Mcf, the 1% leg governs:

  • Crude oil: Greater of 1% of value or $0.24 per barrel
  • Natural gas: Greater of 1% of value or $0.03 per 1,000 cubic feet

Indiana assesses minerals as real property — and paying protects your title

Indiana defines real property to include an estate, right, or privilege in minerals including oil or gas where distinct from surface ownership, and prescribes a uniform valuation method: average daily production times a Board-established posted price times 365, divided by three to reach assessed value. Schedules are filed per lease with the assessor each year showing each taxpayer's proportionate interest. Notably, the regulation assigns royalty and overriding royalty interests a 1.50 factor over working interests because they bear no part of lease expense — an explicit regulatory acknowledgement that a royalty is worth more per unit of production. Paying this bill also counts as statutory "use" that resets the twenty-year lapse clock.

Section-township-range, mostly off the Second Principal Meridian

Indiana is a rectangular-survey state. The Second Principal Meridian governs the great majority of the state including all of the southwestern Illinois Basin oil counties, with the First Principal Meridian along the eastern edge. Three colonial-era overlays are described by tract and lot rather than section — the Vincennes Tract in Knox County, Clark's Grant in Clark and Floyd, and the Gore in the southeast.

Where oil and gas is produced in Indiana

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

  • Illinois Basin (southwestern Indiana) — Predominantly sandstone reservoirs between roughly 1,000 and 3,000 feet, with more than 900 individual reservoirs recognized across roughly 500 fields.
  • Griffin Pool trend, Gibson County — The heart of Indiana oil activity since a 1938 discovery along the Wabash River.
  • Trenton Field (east-central Indiana) — The historic 1886 Ordovician limestone play — largely depleted by around 1910, but it still supports scattered stripper production and creates very old severed-mineral chains.
  • New Albany Shale and coalbed methane — Devonian shale and CBM in southwestern Indiana, included in reported state gas totals.

What this means for Indiana mineral owners

The facts above — who regulates, whether an idle interest can lapse, how production is taxed, and how land is described — are the Indiana-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 Indiana mineral and royalty interests and prices them on the same regulator and production records described here. This is educational background, not legal advice; Indiana oil and gas law is fact-specific, so consult a qualified Indiana attorney about your interest.

Frequently asked questions

Can I lose my mineral rights in Indiana for non-use?

Yes, in principle — but it is easy to prevent. Under Indiana Code Section 32-23-10-2, a mineral interest unused for twenty years is automatically extinguished and reverts to the surface owner unless a statement of claim is filed — a self-executing lapse the U.S. Supreme Court upheld in Texaco, Inc. v. Short (1982). But "use" is defined broadly: production, injection or storage, rentals or royalties, operations on a pooled or unitized tract, and paying property taxes on the mineral interest all count. Because Indiana assesses producing interests as real property, an owner who simply pays the county mineral tax bill each year continuously resets the twenty-year clock.
