The purpose of the optimizer is finding the best performance envelope for the multilateral well productivity considering subsurface constraints like ESP frequency and zonal water...

... The prioritized balancing allocation scheme allocates flow rates to wells within a group based on a specific sequence. Initially, all wells are fully opened, which can exceed the group's rate limits in our case we called them nonlinear state constraints. To address this, wells are sequentially...

The first method is direct upscaling using deep learning, which directly predicts permeability across multiple scales by training with a combination of various sizes of sub-volumes; the second method is physics-constrained upscaling using deep learning, which imposes additional physical constraints...

... constraints. The key objective of optimization is to maximize the amount of recoverable hydrogen while maintaining operational constraints. We adopt a robust optimization approach that maximizes the mean objective function over a set of realizations representing subsurface uncertainty. The objective function...
