Petrel model save datasource exceptioin

Question

To petrel ocean developers - when I try to save model in petrel, I get an exception that it's impossible to save. In logs I see this:

Type : System.Runtime.Serialization.SerializationException, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

I've tried to delete & re-create completions but no result. What should I do?

Answer 1

As a work-around,

• delete or rename the "CompletionsDataSource.dat" file
• reload the project without saving
• save the project again
• recreate the completion displays in WellSectionWindow
