Under the hood
What this estimate is — and isn’t.
We’d rather you understand the tool than trust it blindly.
The ranges come from broad, public rules of thumb for each basin — dollars per net mineral acre for unleased, leased, and producing minerals, scaled by your royalty rate. They are deliberately wide, because honest ranges are wide.
What the tool can’t see is exactly what moves real offers: your title, which wells pay you and where they sit on their decline curves, your operator’s drilling plans, and how much room is left in your unit. That’s the homework our approach page walks through — and that we do at our own cost before any written offer. Nothing on this page is an offer to buy.
Common questions
About this estimator.
Why does the estimator give a range instead of a number?
Because a number would be pretending. Two 40-acre tracts in the same county can differ in value several times over depending on title, royalty rate, which operator holds the lease, and how many wells the unit still has room for. A range is the honest answer until someone does that homework — which we do for free when you’re ready.
What makes mineral values vary so much?
Five things move most of the money: where your acres sit in the basin, whether they’re producing, your royalty rate, how far along the wells’ decline curves are, and how much undrilled potential is left in the unit. The estimator captures the first three; the last two are why a written offer can land above or below the range.
Will using this tool put me on a call list?
No. The calculation runs entirely in your browser — nothing you type is sent to us, stored, or shared. We only know what you own if you choose to tell us.
What royalty rate should I select?
It’s on your lease or any division order you’ve received. Older leases are usually 1/8th (12.5%); leases signed in the last fifteen years often run 3/16ths to 1/4. If your minerals are unleased, the tool skips the question — there’s no royalty rate until a lease sets one.
No pressure, ever
Ready to swap the range for a number?
Most people who call us aren’t ready to sell. We’ll still tell you what you own, what it might be worth, and what we’d pay — then the next move is entirely yours.
No automated calls. No mailers with sight drafts. No follow-up unless you ask for it.
