What are Karnes County mineral rights worth?
Karnes County, in South Texas, is the core of the Eagle Ford oil window and one of the most productive counties in the play. Producing royalties are valued on the 36 to 72 times monthly royalty rule, with strong oil economics. Estimate, subject to verification.
Karnes County, around Kenedy and Karnes City in South Texas, sits in the heart of the Eagle Ford Shale oil window and is consistently one of the most productive counties in the play. Operators target the Eagle Ford and the overlying Austin Chalk with horizontal wells, and the county has some of the best oil-weighted Eagle Ford economics. For mineral owners that means Karnes interests tend to pay strong checks, with both producing royalties and meaningful undeveloped upside in a play that has seen renewed Austin Chalk activity. Texas common-law mineral rules and deep public records make title and conveyance straightforward here.

How Karnes County minerals are valued
Producing interests anywhere are valued on a multiple of the income they pay: roughly 36 to 72 times your average monthly royalty check, the same as 3 to 6 times your annual royalty. Average your last three to six checks, then multiply. Where you land inside that band depends mostly on how fast your wells decline, plus the operator, royalty rate, and any undeveloped drilling upside.

Ironwood Royalty is a principal buyer, which means the offer comes from us and there is no commission in the middle. We show you a value range before we ask for anything, explain the undeveloped upside instead of quietly keeping it, and never use a 72-hour deadline to rush a decision on a generational asset.

- Know your value range before you talk to any buyer.
- Ask every buyer to quote per net royalty acre so offers are truly comparable.
- Ask directly whether the offer accounts for undeveloped drilling upside.
- Confirm the price is firm and not subject to a quiet reduction during due diligence.
