Add detailed petrophysics FMU OPM Flow and NeqSim workflow notebook

[EvenSol]

What changed

Adds notebooks/reservoir/detailed_petrophysics_fmu_opm_neqsim_workflow.ipynb, a new detailed Colab notebook covering the full subsurface-to-facilities workflow:

• synthetic well logs and petrophysical interpretation
• well–seismic tie concept
• 3D static reservoir properties
• vertical upscaling and Eclipse/OPM Flow include-file export
• lightweight dynamic forward model showing the simulator interface
• FMU/ERT-style ensemble generation and history matching concept
• reservoir-to-NeqSim interface table
• process/facility constraint feedback
• end-to-end workflow diagrams

Validation

• A detailed local copy was executed end-to-end before publication.
• 20 code cells executed with 0 notebook execution errors.
• Stored outputs are included for the main numerical steps.
• Plotting/workflow illustration cells are included and execute in Colab.
• Specialist packages such as lasio, welly, segyio, gstools, pyvista, and neqsim are installed automatically when the notebook runs in Colab.

Scope note

The dynamic reservoir calculation is intentionally a lightweight portable forward model. The notebook clearly marks the replacement point for OPM Flow. The FMU update is pedagogical; production use should replace it with ERT ES/ES-MDA. The NeqSim boundary-condition interface is explicit so the process model can be expanded to real wells, gathering, separation, and compression.
