35、 Historical Production Data to the ModelThe last item we want to do is add historical rate data so as we can set up a history match run?Go to the top menu again and select Import Production/Injection data ( this is the wizard to create production/injection data into well & recurrent data for the

36、 simulator and also defines the status of each well!)?STEP 1: First step of this wizard is to provide the type and name of the production file. In our case, we will use General and choose a file in the tutorial directory namedProduction-history.prd?STEP 2: Follow the instructions and highlight the f
