RECORD # 8 : MWD FORMATION EVALUATION

WITS Record ID 8 Logical Record Type 158 Auto/Manual AUTOMATIC
Trigger [TIME], [DEPTH] or [TIME/DEPTH] Transmit at specified time interval (secs), depth interval (feet or meters) based on hole depth when drilling new hole or making a new pass, or a combination of these.
Data Source Data acquired in real-time and computed over the trigger interval. Record transmitted and computations reset when triggering interval occurs. If DEPTH-triggered, then only on-bottom data is included in computations. Depths of MWD sensors transmitted in the record are the depths for the last valid reading for that sensor. Record is not sent if not circulating or tool is not operating
