What You're Actually Dealing With in Union County

Union County, Arkansas sits over the Smackover formation, which has been producing oil since the 1920s and still has active operators working it today. This isn't the Permian Basin — drilling here is more measured and less frenzied — but that doesn't mean your mineral rights are worthless. If you're near a producing well or in a unit with existing production, your rights could be generating royalty income right now or could attract a buyer at a reasonable price. Before you make any decisions about selling or holding, it's worth understanding what's actually happening with drilling activity in your specific area of the county.

What's in the Ground

Smackover

Smackover / Arkla Basin

This is the main event in Union County. The Smackover is a Jurassic-age carbonate formation sitting roughly 7,000 to 11,000 feet deep. It's been producing oil here for nearly a century and remains the primary target for operators working the county today. Wells can be productive, but drilling costs are significant, which is why you see established operators rather than aggressive wildcatters dominating activity.

Cotton Valley

Arkla Basin

The Cotton Valley is a tight sand formation deeper than the Smackover that has historically been a natural gas target. Activity here has cooled considerably with low gas prices, but it adds some secondary value to mineral rights that cover this depth. Don't count on it as a primary driver of your acreage value today.

Haynesville

Arkla / East Texas Basin

The Haynesville Shale edges into portions of southern Arkansas, including parts of Union County. It's primarily a gas play, and while it has been among the most productive shale gas formations in the country in Louisiana and East Texas, its presence in Union County is more peripheral. If your acreage sits in the right area, it could add speculative upside — but it shouldn't be your main expectation.

Questions We Hear From Union County Owners

I got an offer out of nowhere from an oil company. Is it fair?

Probably not the first offer they send. Operators and mineral buyers make lowball offers regularly, especially to owners who inherited rights and may not know their value. The fact that someone reached out to buy your rights is actually a good sign — it means they think there's value there. Get an independent valuation before you respond to anything.

My family has owned these rights for decades. Should I just hold onto them?

That depends on your situation. If there's active production, holding means ongoing royalty income. If the rights are dormant and you're not expecting near-term drilling, selling now gives you certain money today instead of waiting years for activity that may or may not come. Union County isn't a speculative hotspot right now, so the decision really comes down to your personal financial goals and timeline.

How do I find out if there are any producing wells on my acreage?

The Arkansas Oil and Gas Commission (AOGC) maintains public records on permitted and producing wells. You can search by location or owner name. If you know your legal description — township, range, and section — you can find out fairly quickly whether there's a well in your unit. We can also help you look this up if you're not sure where to start.
