Physical Mechanism-Driven Seepage Modeling: Sources of Constraints
Accurately portraying complex physicochemical processes in reservoirs across scales demands deep integration of multiscale physical mechanisms. Molecular Dynamics (MD) provides nanoscale insights (e.g., fluid-solid interactions), the Lattice Boltzmann Method (LBM) simulates pore-scale flow with physical consistency, and Pore Network Models (PNM) efficiently scale up to core-level. These methods provide indispensable physical constraints and high-fidelity training data for AI models, moving beyond traditional Darcy's law limitations for unconventional reservoirs.
The Core Engine: A Fusion Paradigm and Technology Path for Physics-Informed AI
The methodology of physics-informed AI has evolved significantly: from AI as a static surrogate model to Physics-Informed Neural Networks (PINNs) that embed physical laws as strong constraints, and ultimately to Neural Operators (NOs) that learn the solution operator itself. This progression addresses key limitations in generalization, data dependency, and computational efficiency, moving towards "train once, use many" predictions.

|---|---|---|---|
| Core Idea | Train AI to learn end-to-end input-output mapping of complex physical systems. | Embed PDEs as physical constraints in the neural network loss function. | Learn the solution operator for solving PDEs itself (function to function mapping). |
| Learning Goal | A specific solution under specific parameters (parameters → solution). | A specific solution under specific parameters, solved with physical equations. | The operator of the problem itself (function (e.g., permeability field) → function (e.g., pressure field)). |

Engineering Applications: From Digital Platform to Digital Twin
The culmination of physics-informed AI is the construction of an integrated digital platform for E&P, enabling reservoir digital twins. These twins create real-time interactions and feedback between physical reservoirs and virtual models, crucial for intelligent risk prediction, production optimization, and decision support. The technology extends to emerging green energy industries, including Carbon Capture, Utilization, and Storage (CCUS), geothermal energy, and underground hydrogen storage (UHS).
Case Study: Optimizing Carbon Capture, Utilization, and Storage (CCUS)
Researchers leveraged Fourier Neural Operators (FNOs) to create proxy models for CCUS projects. This innovation significantly reduced coupled flow and geomechanical simulation time from thousands of hours to less than twenty minutes, enabling rapid multi-objective optimization for CO2 injection strategies. This demonstrates how AI fusion significantly enhances the safety and reliability of large-scale geological storage projects.
Key Outcomes:
- Simulation Time Reduction: From thousands of hours to <20 minutes.
- Optimization Speed: Enabled rapid, multi-objective optimization for CO2 injection.
- Project Impact: Enhanced safety and reliability of large-scale geological storage.
