This is the computational backbone of groundwater exploration, mineral prospecting, and environmental site characterization. While commercial packages like Res2DInv and Oasis Montaj charge per-survey licensing, the open-source ecosystem now offers production-grade alternatives: SimPEG, pyGIMLI, and ResIPy.</p>
