I build physical-AI surrogates that simulate subsurface flow in seconds instead of hours — neural operators for reservoir engineering.
Reservoir simulation is the bottleneck in subsurface engineering — a single history-matching study can demand thousands of runs, each hours long on a supercomputer. My work replaces that loop with a single neural operator that learns the physics of Darcy flow directly from data, then predicts pressure and saturation fields on unseen permeability, well locations, well controls, and well counts — including forward extrapolation in time. In practice the surrogate runs on the order of a thousand times faster than a conventional simulator while holding relative error under five percent, which opens the door to real-time history matching, well-placement optimization, CO₂-storage planning, and live reservoir digital twins.
