Sell Mineral Rights in Arkansas

Two questions decide how an Arkansas mineral interest should be valued: are you under the Fayetteville shale, and is your tract anywhere near the Smackover brine trend everyone's suddenly talking about.

Arkansas mineral ownership splits cleanly into two very different stories right now, and a calculator has to know which one applies to you before any of its inputs mean anything.

The first is the Fayetteville Shale, a dry natural gas play across north-central Arkansas counties like Van Buren, Cleburne, Conway, and White that had its boom years back in the 2000s and 2010s and today is a mature, slower-decline gas asset. The second is the Smackover Formation across south Arkansas, historically an oil and gas trend, now drawing new attention because its brine carries extractable lithium, and companies are actively leasing and piloting extraction in Union and Columbia counties. These are not the same calculation.

If you're in Fayetteville shale territory

Fayetteville wells are gas wells, full stop, with no oil credit to soften a weak gas price quarter. Most of the play's wells are well past their steep early decline and have settled into a longer, flatter tail, which is actually a reasonably favorable input for a buyer multiple, since the income stream is more predictable than it would be in year one or two of a new well's life. Monthly income for these interests tends to move with Henry Hub pricing more directly than plays with heavier liquids content, so your decline rate assumption should reflect a mature asset, typically single digits annually, rather than the double-digit early declines a newer well would show.

If you're in the Smackover lithium trend

This is a genuinely different animal, and it is where a calculator has to be the most honest about its limits. Lithium brine extraction is an emerging commercial process in Arkansas, and there isn't the decades of production history that oil and gas decline curves rely on. Lease bonuses and royalty structures for lithium are still being defined deal by deal, so if you've been approached about a lithium lease or your tract sits in the active Smackover brine area, treat any value estimate as directional at best. A calculator designed for barrels and Mcf simply wasn't built to handle brine chemistry economics, and pretending otherwise would be dishonest.

That said, some owners in this area still hold traditional oil and gas rights from older Smackover production, layered under the same acreage the lithium companies are now leasing. Those two interests, legacy oil and gas versus new lithium brine rights, may need to be evaluated separately depending on how your deed defines what you own.

The inputs, side by side

Decimal interest works the same in both cases, it's your fractional share of the unit or the leased tract. Monthly income for Fayetteville gas is real trailing revenue you can average from check stubs; for a new lithium lease, monthly income might not exist yet if you're pre-production, and the number that matters instead is bonus per acre and royalty rate in the lease itself. Decline rate is a settled, calculable input for mature Fayetteville wells and essentially undefined for lithium brine operations still in early commercial stages. Commodity price means Henry Hub gas for Fayetteville and, for lithium, a fast-moving global battery-materials market that has swung sharply in recent years. Buyer multiple reflects all of that: steadier and more standard for Fayetteville gas interests, wider and more negotiated for lithium acreage where every deal is still being priced from scratch.
