Reading a Mineral Chain at the Speed a Play Moves

Mineral title is an arithmetic problem buried inside a reading problem. Someone has to find every instrument that touched the mineral estate, then make the fractions close. We built a platform that does the finding fast and checks the arithmetic every time.

Severances do not announce themselves

The deed that split the minerals from the surface was almost never indexed as a mineral conveyance. It was indexed as a deed, and the severance lives in a reservation clause partway down the page. A century of those decisions is why mineral ownership on a given tract can take days to establish and why it is so often established wrong.

Reading the instruments instead of the index is the only reliable answer, and that is expensive unless something reads them for you. Language models do that work here, at a volume that makes a full chain practical on a landman’s timeline, and certified abstractors confirm what comes back. The stack behind it is documented on the AFX technology platform, shared across every AFX property including this one.

The other half of the job is arithmetic, and machines are simply better at it than people working under deadline.

What the platform does

  • Structured mineral data: Interests as fields rather than prose, so fractions, reservations, and the instruments that created them land in your ownership model without anyone retyping a reservation clause. Learn more about Structured mineral data
  • API ordering for multi-tract runs: A play is not one tract. Submit a whole section, a unit, or a lease block programmatically with token-based authentication and a sandbox to test against before it counts. Learn more about API ordering for multi-tract runs
  • Tract and parcel identifiers: Durable identifiers and map overlays for ground described by section, township, and range in one instrument and by a metes and bounds call in the next. Learn more about Tract and parcel identifiers
  • AI-assisted document reading: Severances hide in the habendum and reservation language of deeds nobody indexed as mineral conveyances. Language models read the instruments themselves rather than trusting the index. Learn more about AI-assisted document reading
  • Error correction and classification: Fractional interests are where mineral title goes wrong. Our algorithms revalidate the arithmetic and flag a chain whose fractions do not close, before the report reaches you. Learn more about Error correction and classification
  • White-label reports: Land services firms and brokers deliver the runsheet under their own logo, colors, and disclaimers, with separate templates where a lease check and a full mineral chain should not look alike. Learn more about White-label reports

Ordering a block, not a tract

Leasing and diligence work arrives in blocks. A section, a unit, a whole prospect area. Connected buyers push the set through in one call and watch the states come back per tract rather than keying them individually.

  1. Step 1

    property.add

    Tracts enter the queue

    One tract or a whole lease block arrives by API or portal and is matched against county coverage before research starts.

  2. Step 2

    200 Order Received

    We confirm receipt

    An immediate acknowledgment, so a connected land system can record that the tract is under search.

  3. Step 3

    property.status.update

    The runsheet builds

    Status moves as the abstractor works the chain, instrument by instrument, through the county records.

  4. Step 4

    property.document.upload

    Ownership comes back

    The report arrives with the recorded instruments attached and a structured abstract of the interests beside it.

The REST API handles submission and retrieval for teams running volume, and results come back as a document plus a structured interest abstract carrying each fraction, its interest type, and the instrument that created it.

That second form is the one that matters to a land department. An ownership model built from fields is auditable; one built by retyping reservation clauses into a spreadsheet is a source of exactly the errors this work exists to prevent.

One tract, however it was described

Mineral ground gets described by section, township, and range in one instrument, by metes and bounds in the next, and by a subdivision lot in a third after the surface was developed over it. Durable parcel identifiers and map overlays collapse those descriptions into one referent, so an interest reserved in 1918 still attaches to the tract you are leasing today.

Firms reselling this research deliver it under their own name. Our white-label report templating puts your brand on the runsheet, with separate templates where a quick lease check and a full mineral chain should not arrive looking identical.

Making the fractions close

An undivided interest compounds through every conveyance that follows it. One half of one quarter, then a third of that, then a devise splitting it four ways. When the fractions in a chain do not sum, something was missed, and the report that does not notice is worse than no report at all. Our error correction and classification algorithms check that arithmetic on every chain and route the discrepancy to a researcher.

Upstream, language models extract the reservation and conveyance language that created each interest. What they never do is form an opinion. A records search reports what is of record; determining who owns the minerals today, for a lease or a division order, is an attorney’s work, and these reports are built to be what that attorney starts from.

Questions from landmen and land departments

Can you tell whether the minerals were severed from the surface?
That is the central question in most of these orders, and answering it means reading the chain rather than checking a database. A severance is created by whatever deed first reserved or conveyed the mineral estate, and that deed is usually indexed as an ordinary conveyance. We read the instruments in the chain and report the severance with the document that created it attached.
Can we order a whole section or lease block at once?
Yes. The REST API accepts tracts in bulk, which is the practical way to run a section, a unit, or a lease block rather than keying tracts one at a time. Access is token authenticated, a sandbox exists for dry runs, and land systems typically connect in well under a week.
Can mineral ownership come back as data rather than a document?
Yes. Alongside the report, findings are available as a structured abstract with each interest as a field, including the fraction, the interest type, and the instrument that created it. That is what lets results load into an ownership model or a land system without a retyping step.
How do you handle fractional interests that do not add up?
We surface it rather than rounding it away. Undivided fractional interests compound through every conveyance in a chain, and a chain whose fractions do not close usually means a missed instrument or a defective conveyance. Our algorithms check the arithmetic and route the discrepancy to a researcher, and the report tells you what did not reconcile.
Does a mineral rights search establish who owns the minerals today?
It reports what the county records show of record, which is the evidence a title opinion is built from, not the opinion itself. Unrecorded assignments, probate outside the county, and the effect of lease terms are all things a records search cannot see. Determining present ownership for a drilling or division order decision is an attorney’s work, and our reports are built to be the record research that attorney starts from.
