FAQ
Questions people ask
Are there oil or gas wells near 78839?
Yes. 327 oil and gas wells with a location on the state's map lie inside ZIP code 78839, 196 of them on producing leases, and 873 within 3 miles of its edge. The state issued 26 drilling permits with a well location within 3 miles in the last 24 months, the newest on November 12, 2026.
Is this the same area as the Postal Service's ZIP code?
Nearly. The Postal Service does not publish ZIP code boundaries, so we use the US Census Bureau's ZIP Code Tabulation Area for 78839, built from census blocks where most addresses use that ZIP. The edges can differ from mail delivery by a street or two, and a few ZIP codes (post office boxes, single buildings) have no area of their own.
Do I own minerals under a well in 78839?
A well nearby says nothing about who owns the minerals under it. The county's mineral roll lists who is paid on each producing lease. Search a name to see whether the Zavala County roll lists it.
Where do the numbers come from?
Every dot is a well location from the Railroad Commission of Texas well layers, or a drilling permit's surface location from its permit files, issued in the last 24 months. A well counts as producing when its lease reported oil or gas in its newest months, and as plugged when the state's wellbore record says so. Nothing on this page comes from owners or from addresses.
