This glossary explains common mineral rights terms in plain English so you can better understand your records.

Start with the type of information you are reviewing. Each group covers terminology used in a different part of mineral ownership and oil and gas activity.
Terms that describe the rights associated with a property and how an owner's share may be measured.
Terms that explain how mineral interests may be leased and how different ownership and economic interests are structured.
Terms commonly found in payment records, ownership calculations, and mineral interest evaluations.
Terms used to describe oilfield operations, well status, and the way production may be organized across interests.
From Definition to Document
A glossary definition gives you the general meaning of a word. The surrounding document helps explain how that word applies to a particular interest.
A word in a mineral deed may relate to ownership, while the same or a similar term in a lease may describe a contractual right. Identify the document before interpreting the language.
A royalty decimal, acreage figure, or ownership fraction should be read alongside the relevant property, lease, or payment information. A single number rarely explains the entire arrangement.
Definitions, exceptions, reservations, and other clauses may qualify how a term applies. If the wording affects ownership or legal rights, a qualified title professional or attorney may need to review it.
When the Numbers Need Context
Mineral records often contain numbers that measure different aspects of an interest.
Gross acres represent the total tract acreage, while net mineral acres reflect the owner’s fractional mineral ownership. A royalty decimal represents the share used to calculate production payments.
These figures serve different purposes, and ownership fractions, lease terms, and unit participation can affect the calculations.
Before comparing figures, make sure you understand what each one measures.
Shows the interest described in a mineral conveyance.
Sets out contractual terms for developing the leased minerals.
Shows payment details and may include production, pricing, and deductions.
Identifies ownership and payment information used by the payor.
Connects the records to the relevant state, county, and tract.

No. Gross acreage describes the total acreage of a tract. Net mineral acres represent the acreage attributable to an owner’s mineral interest after applying the ownership fraction. Always check which acreage figure a document is using.
No. A royalty interest generally provides a share of production or proceeds under the applicable arrangement. A working interest generally carries an interest in operations and may carry responsibility for certain development and operating costs. The governing documents determine the specific rights and obligations.
A royalty rate is a percentage established by the applicable lease or agreement. A royalty decimal is a figure used to calculate the share attributable to a particular owner’s interest. The decimal may reflect several factors, including ownership and the applicable royalty terms.

A shut-in well is generally a well that is not currently producing, although it may be capable of production. Certain leases contain provisions addressing shut-in periods and payments. Whether a payment is required or a lease remains effective depends on the applicable terms and law.
Pooling generally combines interests for development or production under an applicable agreement or legal authority. Unitization generally coordinates operations across a broader area or reservoir. The precise meaning and effect depend on the governing agreements and regulatory framework.
Net revenue interest generally refers to the share of production revenue attributable to an interest after accounting for applicable royalty burdens. It is commonly used in oil and gas economics and should not be confused with the percentage of mineral acreage owned.
