It provides read and write access to the binary result files produced by reservoir simulators\u2014RESTART, INIT, RFT, Summary, and GRID files\u2014in both unified and non-unified, formatted and unformatted variants. The package wraps a C++ implementation using cwrap, giving it performance-critical file I/O while maintaining a Python-friendly interface.\n\nOriginally developed as part of the Equinor ERT project, ResData is actively maintained and officially supports Linux and macOS. It depends on numpy, pandas, natsort, typing_extensions, cwrap, and resfo-utilities for its core functionality. The package is suitable for reservoir engineering workflows, simulation result analysis, and data integration pipelines where direct access to simulator output files is needed.","worth_installing":"Yes, with conditions. Install if you work with Fortran-based reservoir simulator output and need programmatic Python access to those files. The active maintenance, recent release, and lack of known vulnerabilities are strong signals. However, the C++ build dependency and GPLv3 copyleft license require upfront consideration\u2014ensure your build environment has a compatible compiler and that the license terms align with your project's constraints."},"id":"resdata","links":{"html":"https://skillfed.io/packages/resdata","md":"https://skillfed.io/packages/resdata.md","pypi":"https://pypi.org/project/resdata/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-13","license_spdx":null,"license_treatment":"copyleft","name":"resdata","python_support":"unspecified","summary":"Package for reading and writing the fortran result files from reservoir simulators"},"popularity":{"monthly_downloads":105733,"position":12684,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"6.3.3"}
