View Telluric Summary Information

A telluric summary is available for each stationary survey listed in the Stationary Survey Maintenance window. Use this feature to quickly determine if telluric current effects are present.

These instructions start with the assumption that the correct pipeline segments have been selected. For information detailing how to select pipeline segments, refer to Select ROWs.

Complete the following steps to view a telluric summary for a stationary survey:

  1. Click Data Entry > Stationary Survey Maintenance to open the Stationary Survey Maintenance window.

  2. Select an option from the Date range drop-down list to filter the data view in the Stationary Surveys grid.

  3. Click Refresh.

  4. Select a stationary survey in the Stationary Surveys grid and then click Info to open the Stationary Telluric Info window.
