OpenShale is a light-weight open-source library for simulating flow in naturally-fractured shale-gas reservoirs based on the Matlab Reservoir Simulation Toolbox (MRST) provided by SINTEF ICT (http://www.sintef.no/projectweb/mrst/). It requires MRST to be added to the matlab path by running "startup.m".
Currently available features include:
- Explicit fracture modeling (EFM)
- 2D Embedded discrete fracture modeling (EDFM)
- Fracture mesh generation with log-LGR
- Random 2D/3D discrete natural fracture generation (ADFNE, Alghalandis, 2017)
- Arbitrary user defined sorption&transport function
- Fully implicit compositional/black-oil solver with automatic differentiation (Krogstad et al, 2015)
- Verified solver against commercial simulator (CMG)
TODO List:
- 3D EDFM verification
- Improved EDFM such as, projected EDFM (Tene et al, 2017) or compartmental EDFM (Chai, 2018)
- More verification of compositional simulation
The code is tested and developed based on MRST 2018a. New version of MRST may cause problmes.
| Example | FileName | Comments |
|---|---|---|
| Case 1a/1b | Case1_MRST_EDFM/LGR_benchmark.m | Single vertical HF with EFM and EDFM |
| Case 1c | Case1_MRST_EDFM/LGR_NF_benchmark.m | Single vertical HF and 3 horizontal NFs with EFM and EDFM |
| Case 2 | Case2_MRST_LGR_benchmark.m | 5 vertical HFs verification case (Jiang et al, 2015) |
| Case 3 | Case3_HistoryMatching_Barnett.m | 28 vertical HFs history matching case of Barnett Shale (Cao et al, 2016) |
| Case 4 | Case4_NaturalFrac_Geomechanics_Barnett.m | Same with Case 3 but with non-planar HFs, random generated NFs and geomechanics effect |
