Sell Mineral Rights in Michigan

If you own Michigan minerals, chances are good they're tied to the Antrim Shale, a gas play that boomed decades ago and has been declining slowly ever since, which is exactly why any per-acre figure here needs context.

The Antrim Shale across the northern Lower Peninsula was one of the earlier successful shale gas plays in the country, with thousands of wells drilled mostly in the 1980s and 1990s using techniques that predate the modern horizontal fracturing boom. Those wells have been producing, often at gradually falling rates, for thirty or forty years in many cases, which gives buyers an unusually long, well-documented decline history to price against.

Because almost no new Antrim wells have been drilled in recent years, Michigan's mineral market today is really a market in mature, aging production rather than a play with meaningful new-drilling upside. That reframes the whole value question: buyers are pricing what's left in an old well's tank, not betting on a coming boom.

What a realistic Antrim Shale range looks like

Producing minerals in established Antrim units with a long, documented royalty history typically price modestly compared to hot shale plays elsewhere in the country, often in the low thousands per net mineral acre for the strongest, most consistent producers, and considerably less for wells well into their decline. Non-producing acreage, or acreage in parts of the play that were never developed, tends to price at a few hundred dollars an acre or less.

Because these wells have been producing for so long, the remaining decline curve is often gentler than you'd expect from a young well, which can make a mature Antrim interest a more stable, if modest, asset than its age might suggest.

Why some counties price higher than others

Otsego, Antrim, and Montmorency counties, among others in the play's historical core, saw the heaviest drilling and have the most consistent production records. Acreage on the fringes of the play, or in counties where only scattered wells were drilled, generally sees fewer comparable sales and more conservative offers, since there's less nearby production to price against.

Small interests and old paperwork

Many Michigan mineral interests trace back to leases signed decades ago, sometimes by a grandparent or great-grandparent, and the paperwork hasn't always kept pace with family changes since. A buyer will want your most recent royalty statements alongside whatever original lease or deed documentation exists, and gaps in that paperwork can slow a sale even when the underlying well is still producing reliably.

If checks have stopped coming or dropped noticeably, it's worth asking the operator directly about your well's current status before assuming the tract is worthless. Old wells sometimes get worked over or recompleted, which can extend production beyond what an outdated statement might suggest.

Getting a real number for a Michigan interest

Gather your recent statements and any lease paperwork, and confirm which county and unit your acreage sits in. Given how mature this play is, a documented, current royalty history is the most reliable thing you can bring to the conversation.
