Working with Telluric Compensation : Using Stationary Survey Maintenance : View Telluric Summary Information
   
View Telluric Summary Information
A telluric summary is available for each stationary survey listed in Stationary Survey Maintenance. Use this feature to quickly determine if telluric current effects are present.
To view a telluric summary for a stationary survey, follow these steps:
1 Select the pipeline segment(s) you want to work with in the Select ROWs window (Figure 14-2).
2 Click Data Entry > Stationary Survey Maintenance to open the Stationary Survey Maintenance window (Figure 14-3).
3 Click the down arrow in the Date range field and select an option in the selection list to filter the data view in the Stationary Surveys grid. Then click Refresh.
4 Select a stationary survey in the Stationary Surveys grid and then click Info to open the Stationary Telluric Info window (Figure 14-5).
See Table 14-3 for a description of the Stationary Telluric Info window.

Telluric Effects
Identifies if the stationary survey shows telluric effects. Result for this field is either True or False.
On Avg (V)
Average ON voltage measurement.
On Min (V)
Lowest ON voltage measurement.
On Max (V)
Highest ON voltage measurement.
Off Avg (V)
Average OFF voltage measurement.
Off Min (V)
Lowest OFF voltage measurement.
Off Max (V)
