Full Wellbore Database (EBCDIC)
The same wellbore database, in the raw IBM mainframe encoding.
What this is
Byte-for-byte the same records as the ASCII wellbore file, encoded in EBCDIC cp037 as the Commission's mainframe writes them.
RRC publishes both because some subscribers feed the file straight into COBOL systems that expect the original encoding.
How it is laid out
The Railroad Commission publishes this as EBCDIC (IBM cp037). IBM mainframe encoding (cp037). Opening it as text gives you nonsense; it has to be transcoded first. 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
Feed a mainframe-era reader without a transcoding step, or verify that an ASCII conversion round-trips.
- 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
EBCDIC is not ASCII and is not UTF-8. Opening this in a text editor produces garbage. Packed-decimal fields inside it are not text at all. Unless you specifically need the original encoding, take the ASCII file, which EZRRC has already parsed.
EZRRC does not parse this file. Upstream has not built a reader for it …
