Interpret curve description codes
We need to find the manual (it might be an SPWLA thing),
But it would be good to verify and or cross-reference the accuracy of these four-couplet numeric codes that are sometimes sitting in the curve description section of LAS files.
00 043 00 00
They aren't standard, but I might be good to make use of them when and if they are recorded.
These are from API, allegedly documented in Recommended Standard Fonnat for Recording Digital Well Log Data on Magnetic Tape, API Bul. 0-9, 3rd edition, 1981.But I can't find this document anywhere, including on api.org, and I can't find anything else in their standards library that looks like it might the successor to it.
However, my guess is that nobody uses them correctly, so...
Damn, that list. It used to be on the CWLS site, but after the site was redesigned a year or two ago it disappeared as far as I can tell.
I found the links I was thinking of:

The other link wasn't archived:
