Sell Mineral Rights in Michigan

The Antrim Shale boom happened before a lot of today's mineral owners were even paying attention to their royalty statements, and a surprising number of those wells are still paying checks decades later.

Michigan's Antrim Shale, centered on Otsego, Antrim, and surrounding counties in the northern Lower Peninsula, was one of the earliest large coalbed methane plays in the country, drilled hard through the 1980s and 90s. If you hold acreage up there, chances are your family's interest has been quietly producing at low, steady volumes for two or three decades, and the check stub you're holding right now is your best evidence for what the interest is worth.

Selling here follows a familiar pattern, but there are a couple of Michigan-specific wrinkles worth knowing before you start.

Register of deeds and title confirmation

Michigan uses the term Register of Deeds for its county land records office, and that's where your mineral deed will be filed and where a buyer's title search starts once they know which county to look in. Antrim Shale deeds from the original 1980s leasing boom are generally well organized, since this was already a modern, established recording system by the time the play took off, unlike some of the older basins in other states where deeds trace back a century or more and legal descriptions can be far harder to reconcile with current parcel maps.

If your interest passed through inheritance without a formal deed executed at each generational transfer, Michigan probate records at the county level will typically fill in the chain, and this is usually a manageable process given how relatively recent most Antrim ownership history is compared to older basins where the paper trail can run back well over a hundred years.

How a decades-old CBM well gets priced

Antrim wells decline slowly and unevenly compared to shale oil plays — a lot of them settle into a long, low, relatively flat tail after the first several years, which actually makes them straightforward for a buyer to price against a solid stretch of division order history. Twelve to twenty-four months of check stubs showing that steady pattern is usually enough for a buyer to build a fair offer without much guesswork on either side of the table.

Because there's essentially no new Antrim drilling happening today, value here comes almost entirely from the remaining life of existing wells rather than any speculation about future activity, so don't expect an offer premised on future drilling potential the way you might in an active shale play still in its early leasing phase.

Closing the sale

Once terms are agreed, a mineral deed and division order transfer get sent to the operator and recorded with the county Register of Deeds, closing out the paperwork side of the sale. Michigan's recording offices are generally efficient, and if your title is clean with no outstanding heirship questions, closing here tends to move faster than in states with older, more tangled deed histories.

If multiple family members hold fractional shares from the same original lease, each can typically sell independently without needing everyone else to agree on timing or terms, which is common with Antrim interests split among siblings and cousins over the decades since the original 1980s leasing.

A note on taxes and paperwork

A mineral sale is generally treated as a capital transaction for tax purposes, separate from how your ongoing royalty income has been reported year to year, so talk to your CPA about how the sale should be handled before you close, particularly if you've held the interest a long time. This is a quick conversation for most sellers but worth having early rather than scrambling the following tax season once the sale is already behind you.

On the paperwork side, Michigan's efficient recording process means most of the delay in a transaction here comes down to how quickly heirs can locate and sign documents, not the state's administrative process itself. A single-owner interest with clean title can often move from signed agreement to recorded deed in under a month.
