Paper presented at the SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, October 12–14, 2021
Paper Number: SPE-205556-MS
..., the target gridded property (such as pressure or saturation) at the next time step. Training and testing datasets are generated by running 13 full physics flow simulations and dividing them in a 12:1 ratio. Nine U-Net models are calibrated to predict pressures/saturations, one for each of the nine grid...

... through implementing financial logic directly inside the model. This novel ability assesses and controls individual well operations every time step, eliminating the need to modify (and rerun) a model after every run due to financial review indicating a well is losing money and needs to be shut...

... as a function of changing the grid size and time step. We used the Peclet number to characterise numerical dispersion with these changes. Time step length was compared with the Courant condition. We also investigated some of the nonlinear elements of the simulation model such as the differences between...

... problem and solved simultaneously for each streamline by Newton-Raphson's procedure. This method is more efficient but can cause unstable solution. The appropriate time step selection is of paramount importance for this solution method. This remains unanswered in the current work, but the results obtained...

..., and a combination of the MFVE and the finite volume element (FVE) methods for the saturation equation. The saturation equation is discretized by means of a time-splitting algorithm that allows an explicit time stepping for FVE applied to the advection equation, and an implicit time stepping for MFVE applied...

... simulator is developed for water flood based on analytical and numerical methods. Oil recovery and water cut from the streamline simulator are compared with their counterparts from a finite-difference simulator. In addition, a practical method to implement an extremely large time step in streamline...
