Oil Detail Well — what it is, in short

What this is

OLA028K. Well-level detail behind the oil proration schedule, one record per well on a multi-well lease, carrying the W-10 test that establishes the well's potential.

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

Break a lease-level oil allowable down to the wells that make it up.

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.

Texas reports oil production by lease, not by well. This file is one of the few places well-level oil detail exists at all, and it is test data rather than production.

EZRRC does not parse this file. Upstream has not built a reader for it yet, so the catalog documents it and links to the …
