Data and code for machine-learning-assisted optimization of well spacing and injection controls for CO₂ flooding in heterogeneous low-permeability reservoirs

Version 1.0.1 provides the corrected code archive, GitHub_repository_upload.zip, including two previously omitted helper modules for independent validation analysis. The unchanged simulation inputs, optimization histories, and independent validation outputs remain available in version 1.0.0 at https://doi.org/10.5281/zenodo.23643183. Reproduction requires the corrected code archive from version 1.0.1 and the three data archives from version 1.0.0. The datasets, trained models, and reported scientific results are unchanged.
