Mineral Title Fundamentals

Before you can run a chain of title, you have to know what's actually being owned. Here's the bedrock: one tract, two estates, and what happens when they go their separate ways.

What "title" even means

"Title" is just a fancy word for who owns what, and how we know it.

In oil & gas, examining title means tracing ownership of the minerals under a tract through a stack of recorded documents (deeds, leases, wills, court orders) until you can say, with a straight face, exactly who owns what today.

But there's a step zero that trips up almost everyone on day one: before you can trace ownership, you have to understand what can be owned in the first place. That's this whole topic. Get it right and the rest of the site clicks into place.

The starting point

Fee simple: the whole bundle

Fee simple absolute is the largest ownership the law recognizes. Own a tract in fee simple and you own it all: the surface and everything beneath it, top to bottom.

The classic way to picture ownership is a bundle of sticks. Each stick is a separate right: to possess the land, use it, sell it, lease it, give it away, or exclude other people from it. Hold every stick and you hold the whole bundle: that's fee simple.

Possess
Use & enjoy
Exclude others
Sell / convey
Lease
Pass by will
Hold every stick at once and you own the tract in fee simple.
Fig. 1 Ownership as a bundle of sticks: each one can be split off and owned separately.

That last point is the whole game: sticks can be separated. You can sell some and keep others. And the most important split in all of mineral title is the one we're about to draw.

The big idea

The two estates

Here's the single most important concept in this entire field. A tract of land isn't really one thing. It's two estates stacked on top of each other:

  • The surface estate, the land you can stand on: soil, buildings, crops, roads, and (usually) the groundwater.
  • The mineral estate, the oil, gas, and other minerals below, plus the rights you need to go get them.

When one person owns the tract in fee simple, they own both estates and the two simply travel together. But (and this is the part that launches a thousand title questions) they don't have to stay together.

Key term
Mineral estate

The ownership of the oil, gas, and other minerals under a tract, together with the rights necessary to explore for, develop, and produce them. It is a real property interest: you can own it, sell it, lease it, and pass it on, all separately from the surface.

Looking closer

The mineral estate's five sticks

Remember the bundle of sticks? The mineral estate is its own little bundle. In many states (Texas is the textbook example) courts describe it as five distinct rights:

01
Develop
Right to explore & produce (and use the surface to do it)
02
Lease
The "executive right": power to sign an oil & gas lease
03
Bonus
Right to the up-front payment for signing a lease
04
Delay rentals
Right to payments that keep a lease alive before drilling
05
Royalty
Right to a share of production, free of cost
Fig. 3 The five "sticks" of the mineral estate: each can be carved off and owned by someone else.

Why drag you through all five? Because any one of them can be severed and owned separately. When somebody owns only stick 5, a share of the royalty with no say in leasing, that's a non-participating royalty interest. When the right to lease (stick 2) is split off, that's a severed executive right. Whole title disputes live in these little splits.

!

Heads up: law varies by state. This crisp "five sticks" framing is Texas-flavored, and other states slice the rights a little differently. The bedrock idea travels everywhere, though: the mineral estate is divisible, and people split it constantly.

"Half of the hard title questions you'll ever get really mean: which stick are we even talking about?"

The plot twist

Severance: splitting the estate

Severance is the moment the surface and the minerals stop sharing an owner. After it happens, you have two separate estates, two separate chains of title, taxed and transferred independently. It usually happens one of two ways:

  • By reservation: a deed conveys the surface but the grantor reserves (keeps) the minerals. Buyer gets the surface; seller walks away still owning what's below.
  • By grant: a deed conveys only the minerals (a "mineral deed"), leaving the surface with the grantor.

Key term
Severance

The separation of the mineral estate from the surface estate, so the two are owned by different people. Once severed, the mineral chain of title can look nothing like the surface chain, which is exactly why we trace them separately.

From the day of severance forward, the mineral chain marches to its own drum. The surface might change hands five times while the minerals sit untouched in one family, or the reverse. Reconciling those two stories is most of what a title examiner actually does.

Who wins ties

The dominant estate

So the estates are severed and owned by two different people. Whose wishes win when they collide: say, the mineral owner wants to drill where the surface owner runs cattle?

By default, the mineral estate is the dominant estate, and the surface estate is servient. The mineral owner has an implied right to use as much of the surface as is reasonably necessary to explore for and produce the minerals (roads, well pads, pipelines) generally without paying the surface owner, unless a contract says otherwise.

Fig. 5 Dominant vs. servient: the mineral owner's right to develop reaches up into the surface.

"Dominant" doesn't mean "does whatever it wants," though. Under the accommodation doctrine, if the mineral owner's planned use would interfere with an existing surface use, and there's a reasonable alternative that still lets them produce, they generally have to take the alternative. It's a balance, not a blank check.

!

State law varies again. The dominant-estate rule and the accommodation doctrine are widely recognized but applied differently across states, and many are now overlaid by surface-use statutes and surface-use agreements. When it matters, check your state.

Bringing it home

Why it matters in title work

When you sit down to examine title, you're almost always chasing the mineral estate. Everything in this topic turns into a checklist of questions you'll ask about every tract:

  • Was the mineral estate ever severed from the surface, and if so, when, and by what instrument?
  • Were any individual sticks carved out: a non-participating royalty, a severed executive right?
  • Who actually has the power to sign a lease, and who's entitled to get paid?

Every one of those answers changes who owns what. Nail this foundation and the next topics (reading the deeds that did the severing, the leases built on top, and the interest math that splits the money) are just details on a frame you already understand.

Test yourself

Quick gut-check

Three quick ones. Think first, then tap to check yourself: no score, no login, nobody watching.

1Maria sells "the land" to a buyer, but the deed says she reserves all oil, gas, and other minerals. Who owns the minerals now?
Maria does. She reserved them, so the surface goes to the buyer and Maria keeps the minerals. The estate is now severed: two owners, two chains of title.
2True or false: a severed mineral owner can generally build a road across the surface to reach a drill site, without buying it from the surface owner.
Generally true. The mineral estate is dominant, with an implied right to make reasonable use of the surface to develop, but it's bounded by the accommodation doctrine (and often by surface-use agreements or statutes).
3Someone owns only the right to receive a share of royalty: no right to lease, no bonus, nothing else. What's that interest called?
A non-participating royalty interest (NPRI): stick #5 on its own, with none of the others. We'll spend real time on these in the interest-calculations topic.
