A-12: DE LA CONCEPCION MARQUEZ, M survey
13,512 acres in Leon County. The state’s records tie 49 wells and 6 drilling permits from the last 24 months to this abstract.
Free. We look for new drilling permits on A-12 (a horizontal well whose bottom hole ends here counts), completions and first production, and email you once a week at most.

What is recorded on A-12
Wells the Railroad Commission ties to A-12: either the operator’s filing names the abstract, or the well’s mapped point falls inside the survey shape. A well here may produce from a unit that takes in other land too.

Drilling permits the state matched to A-12 in the last 24 months. A permit is permission to drill, not a well: some are never drilled.

County deed records
Ask the Leon County Clerk
We have not written up Leon County’s deed records yet. The county clerk keeps the deed records for land in the county. You can call, write or visit, and the office can tell you what is online and what a copy costs.
The deed is what shows who received the minerals. A map of the land, like the one on this page, does not.
Volume and page is the address of a deed in the county’s books.
What to ask the clerk for
- The deed that describes this land, by its recording number: the volume and page, or the instrument number.
- The grantor and grantee index for the names on your family's deeds, so you can find the later deeds too.
- Copies of any mineral deeds, royalty deeds or probate records that mention the land.
Take this with you
A-12, DE LA CONCEPCION MARQUEZ, M survey, Leon County
Hear when something new is filed on A-12
A new drilling permit is often the first sign of a new well, and of new royalty months later. We check the state’s records every week.

The survey shape is from the Railroad Commission’s survey layer, dated Sep 29, 2026. Wells, leases, permits and production are the Commission’s public records as loaded into Royalty Clerk.
