How to Build a Mineral Runsheet
A practical guide for landmen, title analysts, mineral buyers, and oil and gas professionals.
Estimated reading time: 7 minutes
What Is a Mineral Runsheet?
A mineral runsheet is an organized record of documents affecting title to oil, gas, and mineral interests.
Landmen and title analysts use runsheets to trace ownership, identify conveyances, review leases, locate reservations, and prepare title information for further analysis. A runsheet is not usually the final legal conclusion. It is the working record that helps professionals understand the chain of title.
A good runsheet tells the story of the land.
It shows who owned what, when an interest changed hands, what documents affected title, and where potential issues may exist.
Why Runsheets Matter
Mineral title work often involves reviewing large numbers of courthouse records.
These records may include deeds, leases, assignments, probate documents, affidavits, mortgages, releases, stipulations, and other instruments that may affect ownership.
Without a clean runsheet, it becomes difficult to answer basic questions such as:
- Who owned the mineral interest?
- When was the interest conveyed?
- Was there a reservation or exception?
- Was the oil and gas lease assigned?
- Did a probate affect ownership?
- Is there a possible gap in the chain?
- A runsheet gives structure to the title review process. It allows a landman, title analyst, mineral buyer, or attorney to review the relevant instruments in order and understand the history of the property.
What Documents Belong in a Runsheet?
The exact documents included depend on the project, jurisdiction, client instructions, and scope of title.
Common documents include:
- Warranty deeds
- Mineral deeds
- Royalty deeds
- Quitclaim deeds
- Oil and gas leases
- Assignments
- Releases
- Affidavits of heirship
- Probate records
- Estate documents
- Mortgages and satisfactions
- Stipulations of interest
- Pooling or unit documents
- Ratifications
- Corrections
- Court orders
- Divorce decrees
- Trust documents
- Not every document creates a change in mineral ownership, but many documents may still matter. A mortgage, release, probate, or affidavit may provide important context even if it does not directly convey minerals.
Core Runsheet Fields
A practical mineral runsheet usually includes the most important information needed to identify, organize, and review each instrument.
Common fields include:
Instrument Date
The date the document was signed or became effective.
Recording Date
The date the document was recorded in the county records.
Book and Page or Instrument Number
The recording reference used to locate the document.
Document Type
The type of instrument, such as mineral deed, warranty deed, oil and gas lease, assignment, affidavit, or probate.
Grantor
The party conveying or assigning an interest.
Grantee
The party receiving the interest.
Legal Description
The land description affected by the instrument.
Interest Conveyed
The interest transferred, reserved, assigned, or affected by the document.
Notes
Important details, unusual language, reservations, exceptions, missing information, or review concerns.
Review Status
Whether the instrument has been reviewed, needs review, or contains unresolved issues.
Step-by-Step Mineral Runsheet Workflow
1. Define the Project Scope
Before reviewing documents, define the scope of the title project.
Important questions include:
- What county and state are involved?
- What tract, section, township, range, survey, or legal description is being reviewed?
- Is the focus surface title, mineral title, leasehold title, royalty ownership, or acquisition due diligence?
- How far back does the title need to run?
- What documents should be included?
- Clear scope prevents wasted time and helps keep the runsheet focused.
2. Gather Courthouse Records
The next step is collecting the relevant documents.
Landmen may gather records from:
- County clerk records
- Online county databases
- Courthouse index books
- Abstract plants
- Client files
- Prior title opinions
- Lease files
- Probate records
- Photos taken in the courthouse
- This part of the workflow can be time-consuming because records are often inconsistent, scanned poorly, indexed differently, or stored across multiple sources.
3. Sort Documents Chronologically
Once documents are gathered, organize them by date.
Most runsheets are arranged chronologically by instrument date or recording date, depending on client preference and project requirements.
Chronological order helps reveal the chain of title.
It also makes it easier to spot gaps, missing documents, conflicting conveyances, and unusual ownership changes.
4. Identify the Document Type
Each document should be classified.
Examples include:
- Mineral Deed
- Warranty Deed
- Royalty Deed
- Oil and Gas Lease
- Assignment
- Release
- Affidavit
- Probate
- Correction Deed
- Stipulation
- Document type matters because different instruments affect title in different ways.
- A mineral deed may convey mineral ownership.
- A royalty deed may convey a nonparticipating royalty interest.
- An assignment may transfer leasehold rights.
- A probate document may explain how ownership passed through an estate.
5. Extract the Key Parties
For each document, identify the grantor and grantee.
In some cases, this is simple.
In other cases, there may be multiple parties, trustees, executors, heirs, spouses, companies, or agents.
Pay attention to party capacity.
Examples:
- John Smith, an individual
- Jane Smith, surviving spouse
- Robert Smith, executor of the estate of John Smith
- ABC Minerals LLC
- First Bank, trustee
- The capacity of the party may affect how the document should be interpreted.
6. Capture Recording Information
Recording information is essential because it allows another reviewer to locate the source document.
Include:
- Book
- Page
- Instrument number
- Recording date
- County
- State
- If recording information is missing or unclear, flag it for review.
7. Review the Legal Description
The legal description connects the document to the land being reviewed.
Common legal description formats include:
- Section, Township, and Range
- Lot and Block
- Survey and Abstract
- Metes and Bounds
- Subdivision references
- A legal description should be copied carefully. Small errors can create major confusion, especially in mineral title work.
- If the legal description is unclear, incomplete, or affected by poor OCR quality, it should be marked for review instead of guessed.
8. Note the Interest Conveyed
The interest conveyed is one of the most important parts of mineral title review.
Examples may include:
- All right, title, and interest
- An undivided one-half mineral interest
- A 1/16 royalty interest
- An overriding royalty interest
- A leasehold working interest
- Surface rights only
- Minerals reserved by grantor
- Subject to an existing oil and gas lease
- This section should be handled carefully. Extracting what the document says is different from calculating final ownership.
- A runsheet should preserve the language of the instrument and flag uncertain interests for further review.
9. Identify Reservations, Exceptions, and Subject To Clauses
Many title issues arise from language that limits or modifies a conveyance.
Watch for phrases such as:
- Except
- Reserving
- Subject to
- Less and except
- Save and except
- Prior reservation
- Existing oil and gas lease
- These clauses can determine whether minerals, royalties, executive rights, or surface rights were actually conveyed.
10. Flag Issues for Review
A good runsheet does more than list documents.
It also highlights problems.
Common flags include:
- Missing legal description
- Unclear grantor or grantee
- Possible gap in chain
- Missing recording information
- Poor document image quality
- Probate needed
- Ambiguous interest conveyed
- Conflicting conveyance language
- Potential reservation or exception
- Document requires human review
- Flags help title professionals focus on the documents that need attention.
11. Review and Finalize the Runsheet
After the initial runsheet is built, review it for accuracy.
Check:
- Are the documents in order?
- Are grantors and grantees correct?
- Is recording information complete?
- Are legal descriptions accurate?
- Are unclear fields flagged?
- Are notes useful?
- Are document references traceable?
- A runsheet should be clean enough that another landman, title analyst, or attorney can follow the chain without having to start from scratch.
Common Mistakes to Watch For
Guessing From Bad OCR
If the scanned text is corrupted, do not guess. Mark the field for review.
Treating Every Deed the Same
A warranty deed, mineral deed, royalty deed, and quitclaim deed may affect title differently.
Ignoring Reservations
Reservations and exceptions often determine whether minerals were actually conveyed.
Missing Probate Issues
Ownership may pass through estates, heirs, wills, or court orders. Probate documents often matter.
Overlooking Party Capacity
A person signing individually is not the same as a person signing as trustee, executor, administrator, or agent.
Forgetting Source References
Every runsheet entry should be traceable back to the source document.
