Echometer Model-H Operating Manual page 48

Pressing the Enter key accepts the location of the marker on the first anomaly and proceeds to the next anomaly
marker listed. Automatically, the program displays the dashed marker in the vicinity of the location of the second
anomaly echo which is now highlight in green.
The Skip Marker button is used to pass over any downhole anomaly listed in the table but that is presently below
the liquid level or that does not generate a clear echo signal, such as plugged perforations. Any changes made
must be saved using the Enter key. Skip Marker will ignore any changes made and proceed to the next marker.
If a marker is accidentally skipped, the operator must press the Skip Marker key through each selected marker
until the highlighted selection comes back around to the marker in question.
Note that the Acoustic Velocity (AV) is now recomputed based on the new Round Trip Travel Time (RTTT) of
5.061 seconds yielding a value of 1094 feet per seconds for the average AV between the wellhead and the first
gas lift mandrel.
