Mineral Deed vs Royalty Deed vs Assignment

A runsheet should not treat all documents the same. The document type helps explain what the instrument is doing and how it fits into the chain of title.

Grantor conveys an undivided one-half interest in and to all oil, gas, and other minerals in and under the described lands.

A mineral deed can have long-term ownership consequences, so it should be reviewed carefully.

The most important distinction is that a royalty owner may not always have the right to lease, negotiate bonus, or exercise executive rights.

Those rights depend on the language of the instrument and applicable law.

Grantor conveys an undivided one-sixteenth royalty interest in oil, gas, and other minerals produced from the described lands.

Royalty deeds can be easy to misread because people often use the words minerals and royalty loosely. A runsheet should preserve the actual language used in the document.

An assignment does not always transfer mineral ownership. Many assignments involve leasehold rights rather than ownership of the minerals themselves.

Assignor assigns all right, title, and interest in and to that certain Oil and Gas Lease dated January 1, 2020, covering the lands described in Exhibit A.

Assignments are especially important when reviewing leasehold title. A missing assignment can create uncertainty about who owns or controls the leasehold interest.

A royalty interest is usually more limited. It generally relates to the right to receive a share of production or revenue.

A royalty interest may not include the right to lease or negotiate terms.

This distinction matters because a document that conveys royalty may not convey minerals, and a document that conveys minerals may include or exclude royalty rights depending on the language.

When reviewing a runsheet, landmen should avoid assuming that a royalty deed and mineral deed have the same effect.

Leasehold assignments often include attached exhibits. Those exhibits may describe the leases, lands, interests, wells, formations, or counties affected.

A missing exhibit can create a title review issue.

When reviewing assignments, important questions include:

Assignments can become complex quickly, especially when leasehold rights have passed through multiple companies over time.

A document labeled as a deed may not convey minerals. A document labeled as an assignment may affect leasehold rights rather than mineral ownership.

Document labels are helpful, but the actual language controls the review.

A royalty interest should not automatically be treated as a mineral interest.

Likewise, a mineral conveyance may reserve royalty or executive rights.

A grantor may convey land or minerals but reserve part of the interest.

Always review words such as:

Assignments often refer to attached exhibits.

If the exhibit is missing, the assigned lands or leases may be unclear.

Fractional interests can be difficult to interpret.

Examples:

These phrases may produce very different results.

If the document image is unclear, the extracted text may be unreliable.

Bad OCR should reduce confidence and trigger review instead of allowing the system to guess.
