Mineral Rights Value Calculator
Describe the property, county and state, interest type, net acres if known, producing status, recent revenue, and the calculation question.
Before you type a number into any calculator for Alaska minerals, it helps to know why private ownership up here is the exception, not the rule.
Ask a landman in Texas or Oklahoma about mineral ownership and they'll talk about severed estates and county courthouses. Ask about Alaska and the conversation changes almost entirely, because the State of Alaska itself owns the overwhelming majority of subsurface mineral rights on the North Slope, and Alaska Native corporations formed under the 1971 Alaska Native Claims Settlement Act hold most of the rest. Private, individually-owned mineral interests of the kind a typical calculator is designed to price are genuinely rare here.
That doesn't mean nobody reading this owns something worth estimating. It means the first job of a calculator, before it touches decimal interest or decline curves, is figuring out what kind of interest you actually hold. A share of an ANCSA corporation, a net profits interest carved out of a North Slope unit, and a legacy fee mineral interest from before statehood are three separate legal animals, and each one calls for a different kind of homework before a number means anything.
If your interest is a royalty or net profits interest carved out of an ANCSA corporation's land, or a working interest position acquired through a private transaction tied to a Prudhoe Bay or Kuparuk unit, that's the closest thing to a Lower 48 scenario, and a decimal-interest-and-decline-rate calculation applies in roughly the normal way. If instead you hold shares in an Alaska Native corporation, that's a corporate equity interest governed by ANCSA and the corporation's own bylaws, not a severed mineral estate, and no oil and gas value calculator was built to price that. And if you're one of the smaller number of owners with a legacy fee mineral interest from before statehood or from early federal patents, your situation is closer to a conventional Lower 48 fee mineral owner, just sitting in a much less liquid market.
For interests that do fit the standard model, decimal interest is your share of the specific unit, Prudhoe Bay, Kuparuk River, Alpine, or one of the newer North Slope developments. Monthly income is trailing royalty or NPI revenue. Decline rate matters more here than almost anywhere else in the country, because these are giant, mature fields well past peak, and even a modest annual decline compounds over the kind of long production life these fields have had. Commodity price runs off Alaska North Slope crude pricing, which tracks global Brent more closely than it tracks the domestic WTI benchmark most Lower 48 calculators assume, so plugging in a WTI-based strip price will quietly understate or overstate your number depending on the spread that week.
Buyer multiple is the input where Alaska diverges most. The pool of buyers actively pricing North Slope private interests is small compared to Texas or Oklahoma, and thin buyer depth generally means a more conservative multiple, not because the asset is worse but because there's less competition bidding it up.
North Slope production has to move down the Trans-Alaska Pipeline System before it reaches a marine terminal at Valdez, and pipeline tariffs plus marine transportation costs get deducted before royalty is calculated on most leases. Those deductions are larger, as a share of wellhead value, than what a typical Permian or Bakken royalty owner sees, because the distance to market is so much greater. A calculator that doesn't account for post-production deductions specific to TAPS tariffs will overstate your effective monthly income before you even get to the value estimate.
If you think you hold a private North Slope royalty or working interest, start by pulling together your division order, your most recent royalty statements, and any lease or assignment paperwork that shows how your interest was created. If your ownership traces back to an ANCSA corporation, gather your shareholder documentation instead, since that's a corporate governance question first and a mineral value question second, if it's a mineral value question at all. Either way, a rough calculator estimate is only a starting point for a conversation, and the specific documents you can produce will do more to sharpen a real offer than any generic assumption about North Slope production.
