Who Owns the Mineral Rights Under Your Land in North Dakota?

Minerals in North Dakota are a separate estate from the surface. Any deed in the chain can “sever” them — a seller conveys the land but reserves the minerals, or conveys the minerals alone by mineral deed. Severances piled up through the homestead era, the foreclosures of the 1930s (when banks and counties kept mineral interests as they resold land), and every oil play since. Once severed, minerals pass through their own sales, leases, wills, and probates — completely independent of who owns the surface today. After a few generations, it’s common for one 640-acre section to have dozens or even hundreds of mineral owners, each holding a fraction.

Mineral ownership isn’t in a statewide registry. The authoritative record is the office of the County Recorder in the county where the land sits — for the heart of the Bakken, that means counties like Williams, McKenzie, Mountrail, and Dunn. Every instrument that ever moved an interest — patents, warranty deeds, mineral deeds, probate decrees, oil and gas leases, assignments — is recorded there, indexed by legal description (section, township, and range) and by the names of the parties.

Two other public sources round out the picture: the North Dakota state well records, which show every well, its operator and status, and the spacing unit it drains; and district court probate files, which document how interests passed at death.

Answering the ownership question from the raw record takes four steps:

1. Identify the legal description. Mineral ownership is tracked by section–township–range and subdivisions of it (quarters, quarter-quarters, lots) — not by street address. Your deed, tax statement, or county parcel map gives you the description.

2. Pull every recorded instrument for that land. At the recorder’s office (or through the state’s recorded-document system), you search the tract and grantor/grantee indexes and collect every document that touches the land — often several hundred instruments for a Bakken-area section.

3. Build the chain, oldest to newest. Starting from the original patent, you follow each conveyance forward, noting every mineral reservation, fractional conveyance, probate distribution, and lease. Each reservation or mineral deed splits the estate; each death fans an interest out to heirs. The arithmetic — undivided fractions of fractions — is where most mistakes happen.

4. Total the current interests. What remains at the end is the current ownership picture: each owner’s undivided fraction, usually expressed as net mineral acres (NMA).

Done carefully by hand, this is days of work per section — which is exactly why title work is expensive and why so many mineral owners have never actually verified what they own.

Name variations and estates. The same owner may appear as “J.R. Smith,” “John R. Smith,” and “the John Smith Family Mineral Trust.” Missed matches break chains.

Unprobated interests. Minerals frequently pass through generations without a recorded probate, leaving gaps the record doesn’t document.

Fractional math. An undivided 3/32 of the S½ reserved in 1952, split among five heirs, one of whom sold half — small errors compound into wrong acreage.

Abandoned-minerals claims. North Dakota law allows surface owners to claim severed minerals that have gone unused for 20 years if the statutory procedure is followed — another layer of instruments to check.

Spacing units. Production is paid on pooled spacing units that often span multiple sections, so owners in a neighboring section may be paid on a well drilled under yours.

Mineral Truth does the courthouse work in advance. We’ve digitized, read, and cross-checked the complete Williams County record — 443,000+ recorded instruments — and assembled the chain of title for every section. Type a legal description or an owner’s name and you get the current mineral owners, their interests and net mineral acres, the wells and spacing units on the land, and the scanned document behind every link in the chain — in seconds instead of days. See plans and pricing or walk through the tutorial for a step-by-step look at exactly how it works.

However you research it, remember that no summary — ours included — replaces examination by a licensed attorney or professional landman for decisions that depend on title. The value of working from the assembled record is that verification starts from a complete, organized picture instead of a cold courthouse index. More questions? See the FAQ.
