Weighing an offer to sell your Atascosa County minerals?
Buyers make unsolicited offers on mineral rights constantly, and the activity on record here is
the context that tells you whether an offer is well-timed. Atascosa County has
42 new drilling permits in the last year,
1,562 producing wells, 118 horizontal
permits and 16 active operators on record. New drilling — especially horizontal wells
that can drain a tract from a mile away — is what moves both a mineral tract's value and your
leverage in a sale. This page shows that activity free; watching the county tells you the moment it
changes, so an offer never lands before you know what's driving it.
This is public Railroad Commission activity — the same data a mineral buyer looks
at, in your hands. It is not an appraisal, and not a record of who owns the minerals.

This report compiles and structures publicly available oil & gas records from the Railroad Commission of Texas — drilling permits, completions, well status, and lease production. We monitor development activity and public filings near a location you tell us about; we do NOT determine mineral ownership, confirm what you own, or provide legal, tax, or investment advice. Nothing here replaces a title opinion, a landman, or reading the official RRC filing. Activity is mapped to the operator-filed permit surface location (NAD27, precision disclaimed by the RRC), not your mineral tract. Data is current only as of the source vintage shown on the page. Our total liability for any report is capped at the amount you paid for it. Found an error? Reply to any email and a human will correct it.
