In three linesMathematical framework for surrogate modeling of oil reservoirs (Norne, 46×112×22 grid) using Fourier Neural Operators (FNO) and physics-informed variant (PINO). Empirical validation: R²>0.99 (oil), R²>0.90 (gas), R²≈0.80 (pressure) over 3298 days. 10⁴× speedup vs OPM simulator, 1000-member ensemble in <1 min on B200 GPU.
