RECORD # 9 : MWD MECHANICAL

WITS Record ID 9 Logical Record Type 159 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. Record is not sent if not circulating or tool is not operating
