How Berlin actually values a mineral interest.

We say on every page of this site that we show sellers the work behind our number. This page is the work itself: the framework we apply to every interest we price. It is written for mineral owners, their attorneys and CPAs, and anyone who wants to check a buyer's number, ours included. It is general methodology, not an offer or advice about your specific interest.

A mineral interest has up to three components of value, and a serious valuation prices each one separately and shows them as separate lines.

Component one: producing value

The wells already paying you. The method is a discounted cash flow, not a rule of thumb:

1. Start from actual production history, not the check. Monthly volumes for the wells in your unit are public record in most states. The check is the output; the wells are the input.
2. Fit a decline. New horizontal wells commonly lose half or more of their rate in the first year or two, then flatten toward a mature decline, often 5 to 12 percent a year. Where a well sits on that curve is most of its value, which is why a first-year check overstates what the royalty will average.
3. Apply prices. We use the forward strip, not the current spot price, with the oil and gas split taken from the actual revenue mix.
4. Subtract what the lease allows to be subtracted. Post-production deductions commonly run 5 to 15 percent on gas, less on oil, and vary with lease language.
5. Multiply by your decimal and discount to today. The discount rate reflects commodity risk and well risk, not a savings account.

The shorthand many buyers quote, a multiple of 36 to 60 months of income, is a compressed version of this math and is only as good as the decline assumption hiding inside it. Our value calculator runs both the multiple and a real present-value version so you can see when they disagree.

Component two: undeveloped value

The wells not drilled yet. This is the component most mailer offers price at zero, and it is often the reason a buyer wants your minerals at all.

1. Count the remaining locations. Spacing, existing wellbores, and unit configuration say how many more wells physically fit under and around your tract, by formation.
2. Weigh the operator. A location in front of an active, well-funded operator with rigs running nearby is worth far more than the same rock held by an operator who has not permitted a well in years.
3. Check the live signals. Permits filed, rigs working, units being formed, and offset completions are public and current. This is what the activity blocks on our county pages track.
4. Risk and discount each location. Every location gets a probability and a timing assumption, and the result is stated as its own line: how many risked locations, at what probability, worth what today.

Ask any buyer, including us, for that line. A buyer who will not break out what they assigned to undeveloped value is either not doing the work or not showing it.

Component three: title and interest adjustments

What you own, exactly, adjusts everything above: net mineral acres confirmed at the courthouse rather than taken from a letter, the royalty rate on the lease that actually governs (a 1/4 lease is worth twice a 1/8 lease on the same dirt, which is why we quote net royalty acres), burdens such as NPRIs and overrides, depth severances, whether acreage is held by production, and curative work the chain needs. Berlin prices curative into the deal and does that work at our cost; what matters here is that it is identified and stated before you sign, not discovered after.

A worked example

Illustrative numbers, rounded, stated so you can rerun them. Say an owner has a producing royalty paying an average of $740 a month over the last twelve months, on wells past their steep early decline.

• A buyer quoting the common multiple might offer 48 months of income: about $35,500.
• A present-value calculation at a 12 percent annual decline and a 10 percent discount rate over 30 years values the same stream at about $39,800. Our value calculator reproduces this number from those three inputs.
• Now the part the multiple ignores: if the unit has two probable future locations and an active operator permitting nearby, those risked locations carry real value on top, and that value belongs in the offer as its own stated line. If the acreage instead sits in a fully drilled unit with no remaining locations, the honest undeveloped line is zero, and we say so.

Same owner, same checks, and the right answer differs by tens of thousands of dollars depending on facts that never appear on a royalty statement. That gap is why we tell owners never to price minerals off the check alone, in either direction.

What this means for a seller

Three questions expose almost any offer: what decline and price assumptions sit behind the producing value, what was assigned to undeveloped locations and at what probability, and what title facts the number assumes. We answer all three in writing with every offer, and when the math says keeping your minerals beats selling them, we tell you that too.
