Oil Ledger
Twelve months of oil production and fourteen months of allowable, by district.
What this is
OLA013K. The oil proration ledger: per lease, twelve months of production and fourteen months of allowable with the carried balances.
RRC splits it into ten files, one per district or district pair, listed separately on its downloads page. One layout, one MFT folder, one dataset here.
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
Compare oil lease production against allowable month by month, and find leases running an overproduction balance.
- 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 with packed decimals and implied decimal places.
Twelve months only. The historical ledger is where the long series lives.
EZRRC does not parse this file. Upstream has not built a reader for it yet, so the catalog documents it and links to the Commission's own copy rather than pretending to serve rows it does …
