Dataset for Wilmington flow–geomechanics

v2: added MRST well-rate outputs (wellSols_qOs_m3s.mat, wellSols_qWs_m3s.mat) for Fig. 10; expanded README figure-provenance.Data underlying a multiphase-flow and geomechanics modeling study of the Wilmington Oil Field (Los Angeles Basin, California), assessing production- and injection-induced subsidence, stress evolution, and fault stability over the field's operational history (1936–2020). The deposit contains the finite-element and reservoir-simulation grids, raw and processed well production/injection records (derived from CalGEM public data), processed pressure and stress fields exchanged between the flow (MRST) and geomechanical (Abaqus) models, and the curated simulation outputs used to generate the paper's figures.
