Notes:
RSG ID's W5-W8 have been previously decomissioned. _
The differential pressure measurement should be positive. A negative differential pressure indicates no gas flow. Negative differential pressure
may be he result of dirt or water obstructing the pitot tube perforations. Overpulling by adjacent extractions wells may also result in negative
pressure being displayed.
