Primarily a container for one or more channel sets (ChannelSet). In WITSML v2.+, most of the log information is now at the channel set level. The concept of multiple channel sets in a single log is significant change from WITSML v1.4.1.1, where each log represented exactly one group of curves and their data. For more information about log organization and how it works, see the WITSML Technical Usage Guide.

An array of channel sets that comprise this log. A log must have at least one channel set, and may have more than one. The channel set is evaluated in such a way that the channels in the log is a UNION of all of the channels in the array of channel sets. That is to say, the result is also a set, no channel can appear more than once in a given log. |
