Permian Basin Mineral Rights

The Permian is the most active basin in the country, and that activity is exactly why its value math looks different from almost everywhere else.

Run a Permian Basin property through a mineral rights calculator and the first thing you notice is how much the multiple range widens. That is not a bug in the tool. The Permian spans two distinct sub-basins, the Midland and the Delaware, plus the Central Basin Platform between them, and depending on where a tract sits, the input assumptions can shift a lot even for neighboring counties.

The short version: this is a stacked-pay, horizontal-drilling, oil-weighted basin with some of the highest well densities in the Lower 48. That combination tends to support stronger royalty checks per net mineral acre, but it also means a calculator needs decline rate, spacing unit size, and operator activity as real inputs, not afterthoughts.

Why stacked pay changes the spacing input

In most conventional basins, a well produces from one formation and the spacing unit is drawn around that single zone. The Permian is different. Operators in the Midland and Delaware sub-basins routinely target multiple stacked intervals under the same surface acreage — the Wolfcamp A, B, C, and D benches, the Spraberry, the Bone Spring, the Avalon. A single 640-acre or 1,280-acre spacing unit can host several horizontal wells landed at different depths, all draining minerals under the same tract.

That is why the spacing and 'wells per section' inputs matter more here than in a single-zone play. A calculator that only asks about one well ignores the fact that a Permian tract might already have three or four laterals under it, with room permitted for more. More wells per unit, all else equal, tends to push the value range higher, because more of the resource under that acreage gets captured over time instead of leaving gas or oil in place.

Decline rate: steep first, then long

Permian horizontal wells are known for a fast first-year decline — often 60 to 70 percent off the initial rate — followed by a much flatter tail that can keep producing at modest volumes for a decade or more. That two-phase curve is a core assumption behind any credible calculator output for this basin, and it is different from, say, a Bakken well's decline profile or a conventional Permian vertical well from the 1980s that is still on a slow stripper-well decline today.

If your mineral rights sit under a well that is one to three years old, most of the steep decline has already happened, which is a very different input than a brand-new completion. The calculator should be treating 'well age' as a meaningful lever here, because a fresh Permian completion and a five-year-old one on the same lease can produce very different royalty check trends even with similar initial production.

Oil-weighted price realization

The Permian is primarily an oil play, though associated gas volumes have grown enough in some areas that operators face real takeaway constraints and occasional negative gas pricing at the wellhead. For a value estimate, the oil-to-gas price mix input should lean heavily oil-weighted for both Midland and Delaware acreage, with a smaller but non-trivial gas and NGL component.

Because oil trades on a more liquid national and global market than regional gas basis, oil-weighted production tends to see more consistent price realization than gas-heavy basins that get stuck behind pipeline capacity. That is one reason buyers often quote Permian multiples on the higher side of typical ranges — but it is still a range, tied to current strip pricing and each operator's specific gathering and marketing contracts, not a fixed number.

Operator activity and where your tract sits

Core Midland Basin counties such as Midland, Martin, and Howard, along with Delaware Basin counterparts like Loving, Reeves, and Lea County on the New Mexico side, see continuous permitting from large public operators. Flank acreage in less-drilled counties around the edges of the play can sit undrilled for years even with real Wolfcamp or Bone Spring potential underneath it.

This is why 'activity radius' — how many permits and completions have happened within a mile or two of your specific tract in the last 12 to 24 months — belongs in the calculator as a serious input, not a footnote. Two tracts with identical acreage and identical formation names can carry very different value ranges depending on whether an operator has an active development plan nearby or hasn't touched that section since it was originally held by production.
