Paper Number: ARMA-2021-1243
... stochastic hydro-thermal simulations and neural network development. A generic reservoir with a doublet system is used for the numerical simulations with Monte Carlo sampling of input parameters from the uniform distributions of formation properties and operations. The simulation results are used to extract...
