Sell Mineral Rights in Michigan

If you own Michigan minerals, there's a strong chance they're tied to the Antrim Shale, a shallow gas play that boomed in the 1990s and has been quietly declining ever since.

The Antrim Shale runs across the northern Lower Peninsula, centered on the Michigan Basin, with the heaviest development in counties like Otsego, Antrim, Montmorency, and Otsego. It was drilled aggressively through the 1990s using techniques that, at the time, were considered advanced but by today's standards were fairly simple — vertical wells completed in shallow, naturally fractured shale, producing gas along with a fair amount of water, especially early in a well's life.

Beyond the Antrim, Michigan has a longer history of conventional oil and gas going back to the Saginaw Bay area, the Niagaran reef trend around the northern Lower Peninsula (small but rich pinnacle reef fields), and some legacy production near the Michigan-Indiana border. But by volume and by mineral-owner count, the Antrim Shale dominates the state's story.

What an Antrim well's life cycle looks like

Antrim wells typically produce a lot of water in their early years — sometimes more water than gas by volume — before settling into a gas-dominant, slowly declining pattern. Most Antrim wells today are decades into that decline, so if you're holding a producing interest, you're likely looking at modest, steady income from a well that's been running quietly since sometime in the 1990s or early 2000s.

That maturity is actually a point in your favor for valuation purposes — a thirty-year-old well's decline behavior is well documented, which reduces the guesswork a buyer has to do compared to pricing a brand-new completion.

Niagaran reef oil: small fields, different economics

The Niagaran reef trend produces oil from isolated, pinnacle-shaped reef formations rather than a broad, continuous shale layer — each field tends to be small and self-contained, sometimes just a single well or a handful. If your interest is tied to one of these rather than the Antrim, your production profile and check history will look quite different: potentially higher per-well volumes but tied to a much smaller, more localized asset.

Because these reef fields are so individually distinct, there's no substitute for looking at your specific well's actual production data rather than assuming it behaves like a neighboring tract.

Producing vs. non-producing in a mature basin

For producing Antrim or Niagaran interests, recent royalty statements tell the real story — pull several months so a buyer can see the trend rather than a single check in isolation. Given how mature most Michigan production is, a stable, slowly declining pattern is normal and doesn't signal a problem.

Non-producing Michigan acreage, particularly outside the core Antrim fairway, sees limited new drilling interest today — the Antrim boom was decades ago and hasn't been followed by a comparable new play in the state. Value on undeveloped acreage tends to be modest unless there's specific evidence of nearby permit activity.

Ownership and county records

Michigan county register of deeds offices hold mineral title records, and because Antrim development happened across a fairly compressed drilling window in the 90s, a lot of leases and division orders from that era are still the operative paperwork for many owners today. If your name isn't the one on the original lease, expect the title work to trace through whatever inheritance or transfer happened since — common in a basin this age.

If you've got an old division order or lease packet from the original Antrim leasing wave, hold onto it — it's often the clearest starting point for confirming your current ownership share.
