Well logs
1 log loaded from the RRC's log index, the latest received Feb 14, 2022. While drilling (MWD). These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.
