Drilling Permit Master and Trailer
The permit master plus its trailer records, without coordinates.
What this is
The same monthly permit master as OGA049, with the trailer record types included: the field-by-field detail lines that hang off a permit root record, one per permitted field.
A permit can name more than one field. The master alone flattens that; the master-and-trailer file keeps the hierarchy.
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
Recover the full permitted-field list for a permit, which the flat master cannot express, and reproduce the record hierarchy the RRC layout describes.
- 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.
Worth knowing before you use it
Trailer records are keyed to the root by position in the file, not by a repeated permit number, so the file has to be read sequentially — you cannot sort it and keep the relationships.
EZRRC does not parse this file. Upstream has not built a reader for it yet, so the catalog documents it …
