My various reservoir simulations done in Matlab Reservoir Simulation Toolbox (MRST). Can be run in Octave.

• 3D Hydrostatic (gravity) column of incompressible fluid > Script
• 3D Single-phase incompressible fluid (water) simulation (ALL B.C.) > Script
• 3D Single-phase compressible fluid (oil) simulation - constant viscosity over pressure (NO FLOW B.C.) > Script
• 3D Single-phase compressible fluid (gas) simulation - pressure-dependent viscosity (NO FLOW B.C.) > Script
• 3D Single-phase compressible fluid (polymer) simulation - Non-Newtonian fluid (with 2 numerical methods: cell-based, or face-based) (NO FLOW B.C.) > Script
• 3D Single-phase compressible fluid simulation with thermal effect (NO FLOW B.C.) > Script
• Two-phase incompressible and immiscible fluid
  • Simulation of waterflooding to an oil (dead oil) bank
    • 1D Buckley-Leverett simulation > Script
    • 2D Buckley-Leverett simulation > Script
    • Observation of viscous fingering > Script

These scripts are adapted from MRST tutorial codes, but I have modified it.

Note:

• I added some Matlab functionalities used in the scripts that Octave currently doesn't have, such as deval. See in the ./modules/nuwara folder.
• I experienced that plotyy (an Octave function) doesn't work properly. plotyy is used e.g. in Simulation 3 to 6 (above). To fix this, this is my way round (in the command line):
  • Add path: addpath 'C:\Octave\Octave-5.2.0\mingw64\share\octave\5.2.0\m\plot\draw'
  • Run: plotyy

• MRST scripts are called from Google Colab
• For the optimization-related scripts (e.g. computeLorenzSPE10.m), Python optimizers will be used > Porting Python and Octave in Google Colab
• Utilizing GPU in Google Colab to run the MRST scripts, speeding up simulations
