Survey maintenance

Edit Survey Definitions tab

By default, Petra creates two survey definitions for “Actual” and “Proposed” survey data sets.  Note that neither of these default entries can be deleted.  This window also modifies each survey definition’s default color, which can be displayed in the Cross-Section Module.

The Edit Survey Definitions tab allows for any number of different survey data sets to be created, which is usually used for different proposed survey plans.  To add a new survey definition, select “Add Definition” and enter in the new survey definition’s name and description.  To delete a new survey definition, select the desired survey row and select “Delete Definition.” Note that all survey information contained in the deleted survey definition for all wells will be deleted.  

The “Get well count for each definition” button counts the total number of all wells in the project containing survey information in each survey definition.  

Other Survey Options tab

Import Options tab

By default, Petra loads new survey information into the “Actual” survey definition.  The Import Options tab sets which survey definition Petra stores new surveys by default.  Note that importers elsewhere in Petra have the option to change the destination of new surveys.

Set Default Definitions tab

This tab sets the “Active” and “Secondary” definitions for all selected wells (selected in Main Module).  “Active” surveys will be the set displayed in the various modules, as well as the survey used in all calculations requiring survey data.  “Secondary” surveys can be displayed alongside the “Active” survey in the Cross-Section Module and the 3d-Viz Module.

Copy Survey(s) tab

This tab copies survey data from one definition to another for the current well, Main Module selected wells, or for all wells in the project.  This option overwrites all survey data in the destination definition.  In the example below, “Actual” surveys will overwrite all survey data in the “Proposed” definition.
