📚 User documentation

What is fmu-sim2seis?

Calculates synthetic seismic from reservoir simulation model, together with a petro-elastic model.

fmu-sim2seis can be run either from command line, or from ERT, the latter being the preferred option.

Installation

To install fmu-sim2seis, run

pip install fmu-sim2seis

ERT jobs

fmu-sim2seis is divided into a series of separate jobs:

• sim2seis_seismic_forward
• sim2seis_relative_ai
• sim2seis_observed_data
• sim2seis_map_attributes
• sim2seis_cleanup

There exists also a forward model for running petro-elastic modelling, defined in fmu-pem.

In the ERT-file for running fmu-sim2seis, necessary arguments are shown in this example ERT setup.

Beware of hardcoded directory names - they should be replaced by your project path/name.

cd ./ERT
ert gui run_sim2seis.ert

fmu-sim2seis (and fmu-pem) are controlled by a series of .yaml-files which you find in examples of here.

The files modelled_data_intervals and observed_data_intervals.yml are used to define zones/intervals for estimating seismic attributes. sim2seis_config contains all configuration parameters for all parts of fmu-sim2seis workflow, except for observed seismic data, which has its own configuration file - obs_data_config.yml.

Tests

fmu-sim2seis has tests that use the tests/data structure, which contains the necessary input data files.

User interface

Users can visit https://equinor.github.io/fmu-sim2seis/ in order to get help configuring the fmu-sim2seis input data.

Developing the user interface can be done by:

cd ./documentation
npm ci  # Install dependencies
npm run create-json-schema  # Extract JSON schema from Python code
npm run docs:dev  # Start local development server

The JSON schema itself (type, title, description etc.) comes from the corresponding Pydantic models in the Python code.
