Powder River Basin Mineral Rights

This basin has two very different stories layered on top of each other: aging coalbed methane and a newer, oil-weighted Niobrara and Mowry horizontal play.

The Powder River Basin spans northeastern Wyoming into southeastern Montana, with Campbell, Converse, Johnson, and Sheridan counties carrying most of the activity we underwrite. The basin built its reputation on coalbed methane in the 1990s and 2000s, and a lot of the legacy interests we see are still tied to that shallow CBM production. Since roughly the mid-2010s, operators have layered a horizontal oil play on top, targeting the Niobrara and Mowry shales at much greater depth than the coal seams.

Because these two plays sit in the same geographic footprint but behave completely differently, the first thing we determine on any Powder River file is which one your interest is actually tied to, since a shallow CBM royalty and a horizontal Niobrara royalty are priced on entirely different assumptions.

Coalbed methane on the way down

Legacy CBM production across the basin has been declining for years as wells deplete and operators shift capital to the deeper oil-weighted play. If your interest is tied to older CBM wells, we underwrite it as a shrinking, low-decline tail rather than something with meaningful upside, similar to what we see in other mature coal seam gas basins.

Water handling costs remain a real deduction on CBM checks here too, and we look at net rather than gross production when building a decline curve.

The Niobrara and Mowry oil play

Horizontal development targeting the Niobrara and Mowry shales, along with the Turner and other intervals, has been more active in Converse and Campbell counties in recent years, and interests tied to newer horizontal wells behave much more like a typical unconventional oil play: a steep first-year decline followed by a longer, gentler tail. We price these off the same decline-curve framework we use in any active oil shale play, weighting recent months heavily since that data is the most predictive.

It's not unusual for a mineral owner in this basin to hold interests under both an old CBM lease and a newer horizontal unit on the same or adjacent acreage, in which case we treat them as two separate valuations rolled into one offer.

What we look for before quoting a Powder River interest

We need to know which formation your interest is tied to, whether the underlying lease is the original CBM-era lease or a newer instrument, and whether the tract has been re-pooled under a more recent Wyoming Oil and Gas Conservation Commission order to accommodate horizontal development. Files where the original lease has been amended or ratified for the newer play take a bit more time to review but are common enough that we handle them routinely.

Montana-side interests in Powder County and the surrounding area follow a similar pattern but fall under Montana Board of Oil and Gas Conservation rules, which we account for separately since spacing and pooling mechanics differ from Wyoming's.

Clerk and courthouse notes across the basin

Campbell and Converse county clerk offices have handled a high volume of filings across two distinct drilling eras, and it's worth checking whether your legal description references an original CBM-era spacing unit or a newer horizontal unit, since the two can overlap without being identical. We do this cross-check as part of every title review before we make an offer.

Because so much acreage in this basin has been leased, re-leased, and pooled multiple times across two development cycles, we also verify whether your original lease was ratified or amended when the newer horizontal unit was formed, since an unamended older lease can sometimes leave a gap between what it covers and what the current unit actually produces from.
