A Texas field number turns up on permits, completions, production reports and severance-tax filings, and on none of them is the name spelled out. This is the file that makes the rest readable.
How it is laid out
The Railroad Commission publishes this as Fixed-width ASCII. Columns are byte ranges with no separators, described only in a scanned record layout. We mirror the Commission's file exactly as they published it, byte for byte. We have not decoded this one into a table yet, so reading it needs the right tooling.
What we add
Decode field numbers anywhere they appear, and find every field whose name matches a play or a formation.
- Mirrored so the file is here when the Commission's own link is not.
- Documented — what it is, where it came from, and when we last fetched it.
