Once your wells are available, you can import a project structure as defined in a CSV file. This will put the wells in the appropriate project and group. The CSV file will have the following format
Well, Project, Group
Wellname1,Project1,Group1
Wellname2,Project1,Group1
Wellname3,Project1,Group1
Wellname1,Project1,Group2
Wellname2,Project1,Group2
Wellname3,Project2,Group3
Wellname4,Project2,Group3
It will create the following and add the well to the Project/Group
Project 1
Group 1
Wellname 1
Wellname 2
Wellname 3
Group 2
Wellname 1
Wellname 2
Project 2
Group 3
Wellname 3
Wellname 4
To import a Project, select File > Import > Projects
If there is no matching well, the project import will stop with an error message. The import will not proceed until all the wells have been validate and exists.
