Midland CAD 2026 Certified Mineral Roll ZIP: File Order, Formats, and Privacy Limits

Direct answer for mineral owners

Open the file-layout PDF first. It explains the certified archive’s record structure and reveals personal contact fields. Use the recap only for aggregate context. Do not open, search, or republish owner-level PDF, TXT, or CSV rows without a defined need and privacy-safe process.

Key takeaways for mineral owners

• The official ZIP contains seven members totaling 2,400,158,157 uncompressed bytes.
• Start with 2. MINERAL FILE LAYOUT.pdf before touching the much larger record files.
• The layout identifies owner names, addresses, a privacy code, and an email-address field, so record-level handling needs a defined purpose and privacy controls.
• Use 5. MINERAL RECAP.PDF only for aggregate jurisdiction context; it does not identify an owner or property.
• Archive names, sizes, hashes, and layouts do not verify ownership, title, appraisal accuracy, tax treatment, private mineral value, or a transaction result.

Archive guide, not an owner or property result. This article records the structure of one Midland Central Appraisal District archive and three control documents. It does not identify an owner, account, property, tract, well, lease, acreage position, title interest, appraisal result, tax outcome, mineral value, offer, production result, royalty amount, privacy-law conclusion, or legal conclusion. MRX provides educational information and resources only and does not buy mineral rights.

The direct answer is: open 2. MINERAL FILE LAYOUT.pdf first. It is the smallest document that explains how the record-level files are organized and which field categories they contain. Then use 5. MINERAL RECAP.PDF only for aggregate context. Do not begin by opening the enormous TXT or CSV member merely because it is available.

That order matters because the layout identifies owner name, mailing-address, account, acreage, decimal-interest, privacy-code, electronic-communication, and email-address fields. A researcher should define a legitimate task and privacy-safe handling process before touching record-level rows.

Direct answer: a safer file-opening order

Order	Archive member	Observed size	Use in this guide
1	2. MINERAL FILE LAYOUT.pdf	46,370 bytes	Read the field map and limitations before handling row-level data
2	5. MINERAL RECAP.PDF	4,699 bytes	Review aggregate jurisdiction context only
3	7. MASTER INVENTORY LISTING.PDF	2,937 bytes	Identify report-selection parameters, not owner or property conclusions
4	1. MINERAL APPRAISAL ROLL.PDF	59,284,432 bytes	Open only for a defined, privacy-aware record task
5	6. YR X YR APPRAISALS.PDF	16,009,269 bytes	Treat as a separate report with its own definitions and limits
6	3. MINERAL DATA FLAT TEXT FILE.TXT	1,000,697,491 bytes	Do not sample casually; preserve the fixed-position schema and privacy boundary
7	4. MINERAL DATA CSV FILE.CSV	1,324,112,959 bytes	Do not import casually; verify schema, delimiter behavior, and purpose first

This is a control order, not an instruction to open every file. For many readers, the first two control documents and a current question to Midland CAD may be enough.

What the controlled ZIP proves

Midland CAD’s current Open Records page places the 2026 Midland Certified Mineral Roll link under Mineral Files. The linked official ZIP archive returned:

• HTTP status 200;
• content type application/zip;
• content length 140,096,354 bytes;
• Last-Modified 2026-07-28 14:29:04 GMT; and
• SHA-256 61ac40ece8e0f52224c9c95e9d4a22491c040057caa72859a3918de222e7eaa4.

The ZIP central directory listed seven members totaling 2,400,158,157 uncompressed bytes. Those observations establish the identity and structure of the bytes retrieved for this review. They do not prove that every record is accurate, complete, current, legally effective, or applicable to a person or property.

The companion Midland CAD Open Records route guide owns the page hierarchy and the distinction between preliminary rolls, certified mineral files, and notices. This article begins one step later: after the exact certified archive has been retrieved and its member list has been bound.

Start with the file layout, not a billion-byte data file

The member named 2. MINERAL FILE LAYOUT.pdf is only 46,370 bytes and eight physical pages. Its PDF title metadata is MINERAL FILE LAYOUT.xlsx, its creation date is 2026-03-26, and its visible heading says MINERAL DATA EXPORT LAYOUT UPDATED 2/18/2026. The document has no encryption and no embedded JavaScript.

The layout describes a fixed-position record that ends at position 2,260. It includes categories for:

• job, year, property type, and interest type;
• lease, operator, and description fields;
• owner name, care-of, street address, city, state, and ZIP;
• regulatory, jurisdiction, taxable-value, market-value, and exemption fields;
• acres, owner number, lease number, mineral-account identifiers, and decimal interest;
• a privacy code;
• an electronic-communication flag and email-address field; and
• later-position group, exemption, situs, and end-of-file fields.

This is why file order is not just a convenience issue. The layout is the privacy warning. It tells a reader that a bulk import can move personal contact and account fields into spreadsheets, analytics tools, backups, logs, screenshots, shared folders, or model prompts.

This article does not decide what privacy law requires, which values are confidential, or how Midland CAD applies its privacy code. Those are official or qualified-review questions. The safe editorial boundary is narrower: do not open, sample, search, copy, publish, or upload owner-level rows without a defined need, data-minimization plan, access controls, retention plan, and authorized interpretation.

The layout file has SHA-256 f0b34cc4b7a96e6cd5480f350f28554b3af72fc9cfd45959763f76d0aef1b020. That hash binds the reviewed bytes. It does not certify the field map as error-free. Position summaries and detailed tables should be preserved as issued rather than silently corrected when wording or numbering appears inconsistent.

Use the recap only for aggregate context

The three-page 5. MINERAL RECAP.PDF is 4,699 bytes with SHA-256 8ac7f7b8231ffbb31ce2c31db46a4a54546d62605b3d9519cec9c58ced2ab589. It displays aggregate jurisdiction rows and reports 442,395 = TOTAL RECORDS ON TAPE.

That total is not interchangeable with the separate 419,660 mineral interest accounts observation in Midland CAD’s 2025 annual report. The annual-report guide owns that document, page locator, and stated category. This archive recap uses different wording, a different date, and a different source frame. Neither number should be silently renamed, reconciled, or converted into an owner count.

For the annual-report source boundary, see Midland CAD 2025 Report: 419,660 Mineral Interest Accounts on PDF Page 25. The difference between the two source statements is context to preserve, not a discrepancy this article can resolve.

The recap also contains aggregate appraisal figures. Those figures are not a private mineral-rights sale value, an offer benchmark, or a property-specific appraisal conclusion.

The master inventory listing is a control report

The one-page 7. MASTER INVENTORY LISTING.PDF is 2,937 bytes with SHA-256 edabfec36aefc391901530f3e7b9b24a654b22a002608c6f660475f71c5a35aa. It displays report-selection parameters such as job, owner range, whether to print detail and values, and other selection fields.

That makes it useful as provenance for how a report was configured. It is not a public-data tutorial, a field dictionary, or evidence about a named owner or property. The report even displays PRELIMINARY while appearing inside a link labeled certified mineral roll. This guide preserves the strings as observed and does not infer why they coexist or what legal effect either label has.

PDF, TXT, and CSV are different handling surfaces

The archive offers three large record-facing formats, but availability does not make them interchangeable.

Mineral appraisal-roll PDF

The 59,284,432-byte appraisal-roll PDF is a presentation format. It may be easier for a person to view, but searching, copying, or interpreting a row still requires a defined account question and care around personal data. A visible row is not a title determination.

Flat-text file

The 1,000,697,491-byte TXT file appears intended for fixed-position processing with the layout document. A tool that treats it as ordinary delimited text could shift or concatenate fields. A small parsing error can become a large, confident-looking data error.

CSV file

The 1,324,112,959-byte CSV file appears intended for tabular import. Before loading it, a researcher would still need to verify encoding, delimiter and quoting behavior, headers, row counts, null handling, field parity with the layout, and treatment of personal fields. This article did not perform that import.

No row from any of these three members was opened, extracted, sampled, searched, copied, or reproduced for this article. The archive central directory and control documents supplied enough evidence for the article’s bounded job.

A privacy-aware archive workflow

Use this sequence when the official archive is relevant to a defined research task:

1. Record the source route. Save the official page URL, archive URL, retrieval time, response metadata, bytes, and SHA-256.
2. List members without extracting them. Capture exact names, compressed and uncompressed sizes, dates, and archive structure.
3. Open the layout first. Identify record length, field categories, personal fields, account identifiers, and source-defined codes.
4. Open the recap second. Use only source-labeled aggregate context; do not convert it into owner or property counts.
5. Define the exact question. Name the account, field, comparison, date, and reason before touching row-level data.
6. Minimize the data. Extract only fields and rows required for the task. Keep personal contact fields out unless they are genuinely necessary and authorized.
7. Keep a transformation log. Record parsing rules, filters, joins, renamed columns, exclusions, errors, and unresolved mismatches.
8. Separate source facts from conclusions. A row may support a bounded appraisal-record observation; it does not by itself prove ownership, title, private value, or a transaction result.
9. Ask the issuer. Use Midland CAD for official definitions, corrections, current-file questions, and interpretation of district codes.

The Texas Comptroller Midland county directory identifies Midland Central Appraisal District and routes users to midcad.org. That supports issuer provenance. It does not endorse every archive member or validate a particular record.

What this archive does not answer

Do not convert a certified-roll archive into any of these conclusions:

Unsupported conclusion	Separate evidence still required
A person currently owns a mineral interest	Current title chain, instruments, conveyance interpretation, and qualified title review
A row applies to the intended tract	Account, legal-description, tract, lease, and property crosswalk
The appraisal is accurate or final	Current district record, method, supporting data, corrections, protest status, and official response
Appraised value equals private sale value	Interest, title, lease, production, risk, timing, market, and transaction evidence
A bulk file is complete and current	Issuer definitions, as-of date, inclusion and exclusion rules, corrections, and replacement checks
A privacy code authorizes disclosure	Current official interpretation and applicable qualified privacy or legal review
A CSV import preserved every field correctly	Encoding, delimiter, quoting, row-count, field-parity, and transformation controls

For Midland CAD’s appraisal-method boundary, use Midland CAD Mineral Property Page: Three Approaches and the Sufficient-Data Condition. That page owns the district’s source statement about appraisal approaches. This article does not import that statement into archive handling.

Evidence claim ledger and source status

Claim ID	Evidence label	Controlled observation	Boundary
C284-01	ROUTING-ONLY	Midland CAD links the 2026 certified mineral roll ZIP under Mineral Files.	The route does not validate archive contents, completeness, owner identity, property applicability, or value.
C284-02	VERIFIED-OBSERVATION	The controlled ZIP is 140,096,354 bytes with the recorded Last-Modified value and SHA-256.	Response metadata and a hash bind retrieved bytes; they do not validate every record.
C284-03	VERIFIED-OBSERVATION	Seven archive members total 2,400,158,157 uncompressed bytes.	Names and sizes do not prove accuracy, completeness, currency, or fitness.
C284-04	VERIFIED-OBSERVATION	The eight-page layout describes a 2,260-position export with owner/contact and account-related fields.	A layout is not an owner, title, appraisal, tax, value, or legal conclusion.
C284-05	VERIFIED-OBSERVATION	The layout identifies a privacy code, electronic-communication flag, and email-address field.	Field categories may be named; no owner-level value is inspected or republished.
C284-06	VERIFIED-OBSERVATION	The recap reports 442,395 total records on tape and aggregate jurisdiction rows.	The recap does not identify an owner or property and does not reconcile Article 282’s source statement.
C284-07	CONTEXT-ONLY	PDF, TXT, and CSV members have different apparent roles and radically different sizes.	Filename and size do not prove schema correctness, equivalence, or analytical fitness.
C284-08	NON-VALIDATING	No row from the appraisal-roll PDF, flat-text file, or CSV was opened, sampled, searched, or copied.	This guide contains no owner-level or property-level finding.
C284-09	UNRESOLVED-CONFLICT	The layout’s summaries and detailed table are preserved as issued, including apparent inconsistencies.	The article does not silently repair or certify the document.
C284-10	ROUTING-ONLY	The Texas Comptroller directory identifies Midland CAD and routes users to midcad.org.	Issuer provenance does not validate a file, record, appraisal, tax, title, value, or transaction result.

Retrieval, originality, and creative evidence

The exact replacement title and slug were absent before implementation. The canonical generator identifies Dimmit CAD 2026 Certified Mineral Roll ZIP Archive Inventory as the nearest same-cluster page at token-Jaccard 0.3571. That guide owns a Dimmit CAD 22,122,374-byte, 13-member TXT archive inventory and archive-test boundary. This article owns a different issuer, a 140,096,354-byte seven-member mixed-format Midland archive, the control-file opening order, the eight-page layout, and its personal-field privacy boundary. The Midland Open Records guide separately owns page routing. The rejected generic valuation identity is not published.

The archive hash binds the complete retrieved ZIP. The three control-document hashes bind the exact file-layout, recap, and inventory-listing bytes reviewed. Physical-page text was extracted from those control documents, but owner-level record members were not opened.

The hero’s low-oblique sealed archive, seven blank member objects, and privacy boundary are materially different from the inline image’s bright strict top-down control-file workflow. The exact title and keyword were added with deterministic typography and passed OCR. Neither image reproduces an official record, owner row, address, email value, account, property, seal, result, or government affiliation.

The MRX1000-FACTORY-SEO-AEO-2026-08-29 contract applies: information gain over volume, current source identity, stable claim IDs and evidence labels, claim-adjacent official citations, answer-first units, supported FAQs, semantic internal links, exact visible/schema entity parity, exact-title hero/share identity, a distinct exact-keyword inline image, and separate creation, deployment, live-verification, indexing, ranking, retrieval, citation, and conversion states.

These controls improve clarity, reproducibility, accessibility, distribution consistency, and citation eligibility. They do not promise indexing, ranking, retrieval, competitor displacement, or citation by a search or answer engine.

For broader context, use the Texas Mineral Rights Guide. If you want help organizing property-specific documents without turning archive fields into conclusions, book a mineral-rights review.

Frequently asked questions

Which Midland CAD certified mineral roll file should I open first?

Open 2. MINERAL FILE LAYOUT.pdf first. It describes the export structure and field categories before you handle the much larger record-level files.

What is inside the 2026 Midland Certified Mineral Roll ZIP?

The retrieved archive contains seven members: a mineral appraisal-roll PDF, a file-layout PDF, a flat-text data file, a CSV data file, a recap PDF, a year-over-year appraisals PDF, and a master inventory listing PDF.

Does the ZIP prove who owns a mineral interest?

No. Archive provenance, filenames, rows, account fields, and appraisal data do not replace title evidence or a qualified ownership review.

Why are privacy controls important for this archive?

The file-layout document identifies owner names, mailing fields, a privacy code, an electronic-communication flag, and an email-address field. This guide does not inspect or republish any owner-level value.

Does the recap show the value of private mineral rights?

No. The recap supplies aggregate appraisal-district and jurisdiction figures. Those figures are not a private-sale valuation, offer, title conclusion, or property-specific result.
