A reduced-order screening analysis of surfactant-inventory-controlled foam collapse and injection-pressure margin in foam-assisted CO₂ storage

This record contains the preprint manuscript, reproducible Python simulation scripts (foamrom.py, run_analysis_v3.py), and dataset files (results_v3.json) for the study titled "A reduced-order screening analysis of surfactant-inventory-controlled foam collapse and injection-pressure margin in foam-assisted CO₂ storage". The study evaluates how temperature, salinity, divalent-ion content, amine inhibitor residue, and residual oil interact to affect foam apparent viscosity and well-scale pressure margins in depleted hydrocarbon reservoirs.
