If I’m not mistaken, SEG published the SEG-Y rev. 2 draft in early 2015. I’m curious what the timeline is now for a full adoption. Does Kingdom 2016 support rev. 2?

SEG-Y rev. 0:
1 = 4-byte IBM floating-point (aka 32 bit floating point (IBM))
2 = 4-byte, two’s complement integer (aka 32 bit Integer)
3 = 2-byte, two’s complement integer (aka 16 bit integer)
4 = 4-byte fixed-point with gain (obsolete)
SEG-Y rev. 1:
5 = 4-byte IEEE floating-point (aka 32 bit floating point (IEEE))
8 = 1-byte, two’s complement integer (aka 8 bit integer)
Rev numbers are read from binary header 301-302
Thanks, Admin. How about any plans in the near future for full adoption? Timeline?

The best answer can be given by the IHS officials.
By the way, I have just come across this, and wanted to share with you all:
Good stuff! Thanks.
Looks like SEGY rev 2 was published mar 27.
I have a number of problems with rev.2 once I collect them I’ll probably explode somewhere else on the internet.
But today I want to complain about SMT.
Yeah we now have multi segy export, but the export format is still the same, it’s complete garbage. Why can’t you do the basic with regards to rev.1 That being put inline/xline in 189/193. That is the default for everyone else. maybe you want to still be a special snowflake. but really you’re just being a red headed step child. These avoidance of standards is even worse when you export gathers.
Yes kingdoms import tool is powerful, it is one of the few I’ve dealt with that can handle non-ordered data. That is data that maybe sorted like x-line oriented or inline reverse. It does this beautifully. I’ve often used kingdom to cleanup segys to be input into other programs(opendtect/petrel) But really who in their right mind uses 9 and 21 as the default locations for inline/xline?)
