Understanding small mineral interests and your options as an owner.
Get Your Free Mineral ValuationFractional mineral interests are partial ownership shares in mineral rights. Instead of owning "all minerals" under a tract, you might own 1/16, 1/32, 1/64, or an even smaller fraction.
These small interests are extremely common—the result of minerals being divided among heirs over multiple generations. Understanding your options as a fractional interest owner can help you make the best decision for your situation.
Generation 1: Great-grandparent owns 160 mineral acres
Generation 2: Four children each inherit 40 mineral acres
Generation 3: Each child has 3 children → 12 grandchildren own ~13.3 acres each
Generation 4: Each grandchild has 2 children → 24 great-grandchildren own ~6.67 acres each
This "fractionation" continues with each generation. After 4-5 generations, individual owners may have interests measured in hundredths or thousandths of the original tract.
Minimal royalties: Small interests generate small checks—sometimes just dollars per month
Administrative burden: You still must track paperwork, respond to division orders, update addresses
Tax complexity: Even small royalty income requires tax reporting
Coordination challenges: Many owners makes leasing and selling complex
Suspended payments: Operators may suspend checks below minimum thresholds
Estate complications: Passing small interests to heirs creates more fractionation
Fractional interests are expressed in different ways:
| Expression | Meaning | Context |
|---|---|---|
| 1/32 of 160 acres | 5 net mineral acres | Fractional ownership |
| 0.00390625 decimal | Your share of production | Division order interest |
| 5 NMA | Net mineral acres owned | Common industry term |
Your decimal interest on division orders shows your exact share of production revenue. If the well produces $100,000 and your decimal is 0.00390625, your royalty is $390.63.
Continue receiving royalties, manage paperwork, and pass to heirs (creating more fractionation).

Request Your Free ValuationA fractional mineral interest is partial ownership of mineral rights, expressed as a fraction (like 1/16 or 1/64) or a decimal. These small interests typically result from inheritance divisions over generations, where minerals are split among multiple heirs, creating increasingly smaller ownership shares.
Each generation that inherits minerals typically divides them further. If a grandparent owned 160 acres and had 4 children who each had 4 children, the original interest is now split 16 ways. After several generations, individuals may own fractions like 1/128 or smaller of the original minerals.
Yes, fractional mineral interests can be sold independently. You don't need permission from other owners to sell your share. Buyers actively purchase fractional interests, though very small interests may be more challenging to sell or may need to be aggregated with other sellers.
Small interests generate minimal royalties that may not justify the administrative burden. You still must track paperwork, file taxes on royalty income, update addresses with operators, and manage the asset. The cost of managing a small interest can exceed its economic benefit.
Many owners of fractional interests choose to sell because the lump sum payment provides more practical value than small ongoing royalties. Selling also eliminates administrative hassle, simplifies your estate for heirs, and converts an illiquid asset into usable cash.
