Thanks for the contribution, this is highly appreciated! I have not yet tested the LGR part of this, but we can do that when we enable these as regression tests for Flow. Everything looks perfect at this point in time, so I will merge this. However, please double check the copyright notice on the first model. It reads TNO, but should maybe be Equinor?

@Negar-Khoshnevis Have you checked the copyright?

The copyright is changed and updated.
