expreccs#
A framework for dynamic regional-to-site boundary conditions in CO2 storage simulations.
expreccs creates integrated regional, reference, and site models and projects dynamic boundary conditions between nonconforming OPM Flow grids. It supports pressure-interference studies, comparison of boundary treatments, and reproducible regional-to-site modeling workflows.
Understand the two-stage regional-to-site workflow and project context.
Install expreccs, OPM Flow, and optional visualization tools.
Define integrated reference, regional, and site models in TOML.
Run integrated studies and project boundaries between existing decks.
Quick installation#
Install the current development version:
pip install git+https://github.com/cssr-tools/expreccs.git
See Installation for virtual environments, OPM Flow, ResInsight, plopm, optional LaTeX support, and installation from source.
Quick start#
Run an integrated regional, reference, and site study:
expreccs -i examples/example1.toml -o hello_world
Project dynamic boundary conditions between existing regional and site models:
expreccs -i "tests/regional/REGIONAL tests/site/SITE" -o projected
Display the available command-line options:
expreccs --help
See Examples for complete workflows, Configuration reference for TOML settings, and Command-line reference for exact syntax, accepted values, defaults, and workflow compatibility.
What can expreccs do?#
Generate reference, regional, and site corner-point models with heterogeneous properties, faults, hysteresis, salinity, wells, and operational schedules.
Map pressure, pressure increase, flux, and pore-volume effects from regional models to regular or irregular site boundaries.
Evaluate open, projected, two-point, per-FIPNUM, projected-pore-volume, and boundary-well approaches against a reference simulation.
Reproduce the 2025 hierarchical regional-to-site study using the
configurations and scripts under examples/paper_2025.
