3 Outline OPM initiative OPM Flow an open source research tool for reservoir simulation IOR centre Task 6 activities

4 Open Porous Media Initiative (OPM) OPM encourages open innovation and reproducible research for modeling and simulation of porous media processes. All OPM software is open-source. Other (current and former) partners: Uni Research CIPR University of Bergen Total University of Stuttgart University of Heidelberg

5 Open Porous Media Initiative (OPM) OPM is the part specialized for porous media OPM can use good parts from other libraries OPM is much more than Black oil two-phase solvers, upscaling, pressure-solvers, transport-solvers, etc.

6 Open Porous Media Initiative (OPM) Installation (releases twice a year): Open-source (GPL v3+) Ubuntu/Red Hat packing system Run OPM-Flow using a virtual machine Install from source on Linux and Mac OS X

7 OPM-Flow OPM-Flow is the black-oil simulator in OPM OPM-Flow reads and writes Eclipse files

8 OPM-Flow Features Fully implicit model for mulation based on Automatic Differentiation and TPFA1 : black-oil with dissolved gas and vaporized oil rock-dependent capillary and relative-permeability curves end-point scaling and hysteresis oil vaporization control EOR options: Todd-Longstaff type polymer model with adsorption, dead-pore space, permeability reduction, and shear effects (Flow-polymer) extra component equation(s), such as a solvent model (Flow-solvent) Performance: 2014: 60 slower than Eclipse100 on SPE cases 2015: 8 slower than Eclipse100 on Norne field model 2016: 2.2 slower than Eclipse100 on Norne field model 2017: 1.5 slower than Eclipse100 on Norne field model Other features: Code review via github merge requests Performance monitoring on linuxbenchmarking.org Parallel version of flow working for limited number of cores

9 OPM-Flow improvements lately Increased user-friendliness: Standard Eclipse input Standard Eclipse output Reasonable error messages Increased speed Increased robustness These are efforts are mainly outside the IOR centre of Norway

10 Norne (to catch up with industry standard)

11 NORNE field model (SOIL)

12 NORNE field model (SWAT)

13 NORNE field model (D-2H)

14 NORNE field model (E-3H)

15 Task 6 Reservoir Simulation Tools

16 Task 6: UoS activity PostDoc Pål Andersen (UoS) & Steinar Evje (UoS) Research Focus: The upscaling part where we will gain insight on how the equations should look like for a field scale simulation. Better modeling of reactive single phase-flow in a fractured porous media MgCl2 brine behavior with diffusion Dissolution/precipitation Ion-exchange Better modeling of pressure driven two phase-flow in a fractured porous media Pressure driven flow along fracture Capillary driven flow from matrix Design of transfer function in dual porosity setting The results of the above works provide insight to be used in a full simulator (OPM)
