resfo-utilities
A utility library for working with the output of reservoir simulators.
Decision gist · record as of 2026-08-14
Yes, if you work with opm-flow or similar reservoir simulator output and need Python-based utilities to parse and process results. The active maintenance, modern Python support, and lack of known vulnerabilities make it a safe choice. The LGPL-3.0-or-later license is acceptable for most open-source and research use; verify compatibility if your project has proprietary distribution requirements.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11 or later (supports up to 3.14); numpy, scipy, natsort, and resfo must be installed as runtime dependencies.
- Medium install friction due to compiled wheels for multiple Python versions (3.11–3.14) and platform combinations.
- Active maintenance with a release 7 days ago; repository is not archived and remains under active development.

What it is and what it does
resfo-utilities is a Python library designed to work with output files from reservoir simulators, particularly opm-flow. It abstracts away the complexity of parsing and manipulating simulation results, allowing engineers and researchers to focus on analysis rather than file format handling. The package depends on numpy, scipy, natsort, and resfo for its core functionality.
The library is actively maintained (latest release 7 days ago) and supports modern Python versions from 3.11 through 3.14. It is distributed under LGPL-3.0-or-later, which means any modifications or derivative works must be shared under the same copyleft terms. The package carries medium install friction due to its compiled wheel distribution across multiple platforms and Python versions.
Use it for
- Parse and load output files from opm-flow reservoir simulations for post-processing analysis.
- Extract specific data fields or time steps from simulator output for visualization or reporting.
- Automate workflows that depend on reading and transforming simulation results across multiple runs.
- Integrate reservoir simulation data into Python-based engineering pipelines or data analysis frameworks.
