1Measurement precision
If traditional methods are used to generate subsurface property data, then comprehensive subsurface property relationships can be established, but the process requires months for data generation and is computationally challenging
Solution Approach 1:
The system performs preliminary training of machine learning models using training input data and training subsurface property datasets before actual deployment. This preliminary action pre-establishes the subsurface property relationships, so when target input datasets are provided, the model can immediately generate subsurface property data without requiring months of computation. The model learns from historical training data and applies this knowledge to new target data, dramatically reducing data generation time while maintaining accuracy.
2Reliability
If traditional computational methods are used for complex oil-water-gas systems, then accurate subsurface property relationships can be modeled, but computational requirements become extremely challenging
Solution Approach 1:
The system replaces traditional mechanical/computational numerical methods with machine learning models. Instead of using computationally intensive numerical simulations to model subsurface property relationships in complex oil-water-gas systems, the system trains neural networks or other ML models on training data. Once trained, these models can predict subsurface properties with high accuracy but with minimal computational energy consumption, effectively substituting heavy mechanical computation with learned patterns.
3Reliability
If traditional methods are used to account for uncertainty in subsurface data, then comprehensive uncertainty analysis can be performed, but the process becomes even more computationally intensive and time-consuming
Solution Approach 1:
The system incorporates uncertainty by providing ranges or distributions of target input data parameters rather than single deterministic values. The machine learning model processes these parameter variations and generates corresponding subsurface property predictions with associated uncertainty measures. This approach allows comprehensive uncertainty analysis without the exponential computational cost of traditional Monte Carlo simulations or other rigorous uncertainty quantification methods, maintaining productivity while improving reliability.
