Questions people ask

Where do the ZIP code areas come from?

From the US Census Bureau's ZIP Code Tabulation Areas, its public map of the area each ZIP code covers, built from census blocks. The Postal Service does not publish ZIP code boundaries; the Census areas match them closely but not to the street.

Why is my ZIP code not listed?

The list below holds the ZIP codes with 10 or more wells inside them. Every other Texas ZIP code still has its page: type it in the box above to see the wells nearest to it.

Does a well in my ZIP code mean I own minerals?

No. Minerals are owned tract by tract, often apart from the land. The county's mineral roll lists who is paid on each producing lease.
