Sheridan County mineral rights and royalty buyers

Sheridan County at a glance

This page is about Sheridan County, Montana. North Dakota has a Sheridan County too, farther south around McClusky. The Montana county sits in the northeast corner of the state, with Saskatchewan to the north and North Dakota to the east. Plentywood is the county seat, and Medicine Lake is one of the other communities. The Census Bureau counted 3,539 people in 2020 and estimates 3,436 for 2025, across about 1,677 square miles, and 27.2 percent of residents are 65 or older (Census QuickFacts).

It is open prairie and wheat country, and the photo below is a vantage point at Medicine Lake National Wildlife Refuge, which the Fish and Wildlife Service puts on the glaciated rolling plains of northeastern Montana.

What Sheridan County sellers should know

Part of the Fort Peck Reservation extends into Sheridan County, according to that same BIA guide. If your minerals are tribal or allotted trust, the BIA's Fort Peck Agency handles leasing, and we don't expect to be able to buy them. Our Roosevelt County page has the longer explanation. Fee minerals are the ordinary Montana kind, under Board rules.

Many Sheridan County interests are small royalties from old wells, and many are held by heirs who live elsewhere. Our ownership guide and the Montana State University Extension guide to oil and gas leasing are good places to start sorting out who owns what. A check stub with a lease and well name helps more than anything else.

Our Bakken page says we buy where title is clean and the geology still works, and in Sheridan County that is especially true. We read each tract and make offers where the numbers support one. The Board's rules for mineral and surface owners are at dnrc.mt.gov, and the state production tax for non-working interests such as royalty is 15.10 percent (Montana Department of Revenue).

BLM's October 27, 2026 Montana-Dakotas sale offered one Montana parcel, in Musselshell County, so nothing in Sheridan County. Sale notices are on BLM's Montana-Dakotas page.

How Fort Union buys in Sheridan County

We buy as principal, with our own capital, and we don't charge a commission. There are four steps. First, you send the county and legal description, plus anything else you have, such as net acres, a decimal, or a royalty stub. Second, we build the runsheet and map the tract into current spacing. Third, you receive a written cash offer that states the interest we think we're buying and the assumptions behind the number. Fourth, if you accept, we draft the mineral deed, handle tax proration and recording, and wire the funds at closing. Typical close is 21 to 45 days, and we pay standard closing costs on deals we complete. You can read the full steps on the process page. If a Sheridan County tract is small, we'll say so up front and tell you what we can and can't do.
