What You Should Know Before You Decide Anything
Duval County is a long-producing, gas-dominant county in South Texas — not a speculative play, but a mature basin with documented output. With 550 producing wells and over 299 billion cubic feet of cumulative gas production recorded by the state, there's real activity here, not just potential. That said, this isn't a Permian-style boom county, so values per acre tend to be more modest and depend heavily on where your acreage sits relative to existing production. If you've received an offer, it's worth understanding the market before you sign anything — buyers don't reach out unless they see upside.
