Main: Project > Settings > Well Symbols
The Well Symbols window changes how Petra interprets and displays the codes already assigned to the wells.
This changes how every symbol code in the project appears on the Main and Map Modules. To change an individual well's symbol see the Main Module's Wells tab.
A well symbol code is a 1 to 8 character value that encodes the general type of well. In the example below, gas wells have a well symbol code of "GAS." Petra uses a set of "well descriptions" to assign well symbols and colors to different kinds of wells on the Main and Map Module.
