Eagle Ford Shale Mineral Rights
The first year on an Eagle Ford well can pay like nothing you've ever seen. The second and third years tell you the real story.
The Eagle Ford runs across a wide band of South Texas, and it's really three different plays wearing one name, depending on where you are. Karnes and DeWitt counties sit in the oil window, further west and south you move through a condensate band, and out toward the Mexican border it shifts into dry gas. Where your acreage falls inside that band matters more than almost anything else for what your interest is worth.
What ties all three windows together is the decline curve. Understanding that curve is the key to understanding whether your Eagle Ford interest is still worth holding or better sold now.
Three Windows, Three Different Basins Under One Name
In the oil window through Karnes, DeWitt, and Gonzales counties, wells produce mostly crude with associated gas, and that's where operators like EOG concentrated a lot of their core development. Move southwest and you hit the condensate and wet gas window, where the product mix shifts and pricing gets more complicated. Further out still, it's dry gas, which trades entirely on gas price rather than oil price.
Two neighboring tracts can sit in different windows and produce completely different economics, so knowing exactly where your acreage falls matters before anyone quotes you a number.
Why Shale Wells Fall Off a Cliff — And What That Means for What You're Owed
Eagle Ford horizontal wells typically lose a large share of their output within the first twelve to eighteen months, then settle into a much shallower decline that can continue for years. That means the fattest checks come early, and owners who got used to those first-year numbers sometimes feel like something's wrong when the third or fourth year check is a fraction of that. It isn't wrong. It's just the normal shape of a shale well's life.
If your wells are still in that first steep stretch, there's an argument for waiting since the near-term value is still high. If they've already flattened out into their long tail, that's a different conversation about remaining life and what it's worth today.
Selling After the Steep Part Is Over
Once a well has moved past its initial decline and settled into its long, low tail, a lot of the guesswork is gone. We can look at eighteen months or more of actual production history and value the interest against what it's realistically likely to keep producing, rather than against hopeful projections.
For owners with Eagle Ford interests that have already flattened out, that's often the point where selling makes the most sense, because you're not giving up much upside that hasn't already happened.
We also see owners who inherited an Eagle Ford interest partway through its life and never saw those big first-year checks at all, just the flatter tail that came after. If that's your situation, there's no missed opportunity to mourn. You're simply valuing the interest at the stage it's actually in, and that's a perfectly normal starting point for a sale.
Questions We Would Ask If These Were Still Our Minerals
These are practical questions an owner can answer without arriving with a perfect title file or a commitment to sell.
Why is the Eagle Ford called three different plays in one?
Because the produced fluid changes as you move across the trend, from an oil window in the core counties to a condensate and wet gas band further southwest, and finally to dry gas near the border. Where your acreage sits determines the economics.
Why did my Eagle Ford check drop so much after the first year or two?
That's the normal decline curve for a horizontal shale well. Most of the output comes in the first twelve to eighteen months, then production settles into a much shallower, longer tail. It's expected, not a red flag.
Is it better to sell before or after the steep decline?
It depends on your risk tolerance. Selling early captures value tied to the steep early production but gives up any upside. Selling after the well has flattened is more predictable because there's less guesswork left in the numbers.
How do I know which window my Eagle Ford acreage sits in?
Send us your legal description or county, and we can tell you generally where your tract falls relative to the oil, condensate, and dry gas windows before we talk numbers.
I inherited this interest after the wells were already flattening out. Does that change anything?
Not really. We value your interest based on its current production and remaining life, whether you've owned it since the boom years or inherited it more recently. There's nothing lost by not having seen the early checks.
Can I sell just my oil-window minerals and keep my dry-gas acreage?
Yes, if you own minerals in more than one window along the trend, we can structure a sale around just the portion you want to sell, leaving the rest of your holdings untouched.
Tell us the county and state, how the minerals came to you, whether they are producing, and which records are close at hand.
