Valuation methodology

We show our work. No black box.

We don't hand you a royalty portfolio without showing the math. Every package comes with a one-page worksheet you can take to your CPA. Here is exactly how we value it, broken into six inputs.

01

Reserve assumptions.

We model your well or unit’s remaining production using a combination of operator-reported volumes, public state filings, and our internal type-curve library. For unconventional plays we model both the initial-production rate and the b-factor that governs decline.

Operator monthly reportsTX RRC / OK OCC / ND DMRInternal type-curve libraryEnverus comp data
02

Recent comparable sales.

Actual closed transactions in your basin and county over the past 18 months. We do not use basin-wide averages pulled from public reports — those mask county-level variance that can move a fair offer by 30%.

Recorded county deedsPeregrine acquisition historyOperator divestiture dataMineral marketplace prints
03

Decline curve.

Tight-oil and tight-gas wells follow predictable decline patterns: aggressive early loss (Year 1 down 60–85%) flattening into a long terminal tail. We model your specific well using a hyperbolic decline with a b-factor calibrated to the basin and operator.

04

Discount rate.

The discount rate translates future cash flows into present value. For typical mineral acquisitions we apply 10–15%, adjusted for basin risk, operator credit, commodity strip, and time-to-payout. The specific rate used for your interest is shown on the worksheet.

05

Sensitivities.

Three scenarios on every worksheet: what the offer becomes if oil drops $10/bbl, if gas drops $0.50/Mcf, or if production declines 10% faster than modeled. Lets you and your CPA stress-test the number before deciding.

06

The written worksheet.

Everything above lands on a single page, plain English, with the math broken out so you can audit it. Reserve estimate, comp range, discount rate, sensitivity scenarios, and the resulting valuation range — the worksheet that comes with every portfolio you review.
