FAQ

Questions people ask

Are there oil or gas wells near 77857?

Yes. 86 oil and gas wells with a location on the state's map lie inside ZIP code 77857, 71 of them on producing leases, and 278 within 3 miles of its edge. The state issued 15 drilling permits with a well location within 3 miles in the last 24 months, the newest on August 27, 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 77857, 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 77857?

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 Milam 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.
