Examples

Norne model case

Brugge model case

The Egg model case

The Egg model is a synthetic reservoir model developed by J. D. Jansen et al., 2013 [1].

Data files

The Egg Model - data files [2]

Modifications to the simulations setup

A few modifications to the original Egg model input file Egg_Model_ECL.DATA are required in order run Flownet.

The COMPAT section is changed to have differences in depth between injectors and producers. With this, we avoid problems related to degenerate tetrahedrons that we would otherwise obtain in the triangulation procedure for the network generation.

Then you can run - OPM Flow to update input files to FlowNet

flow Egg_Model_ECL.DATA

Assisted history matching example

The following YAML configuration file for FlowNet was used to train the data-driven version of the Egg model:

To run the assisted history matching in FlowNet:

flowet ahm /config_file_directory/egg_parameters.yml  output_directory
