2D borehole acoustic finite-difference simulation in Python.
Models in PyBORACS include:
- Open hole and cased hole
- Subsurface model with heterogeneities (fracture, shale lamination)
- Wellbore environments (steel casing, mud cake, invaded zone, washout)
- Oil-water contact
Here is a simulation example based on the following model details:
| Components | P-Velocity [m/s] |
|---|---|
| Sandstone (Sw=100%) | 3,000 |
| Sandstone (Sw=20%) | 2,700 |
| Shale laminae | 1,800 |
| Fracture | 1,500 |
| Steel casing | 6,000 |
| Cement | 2,400 |
| Mud cake | 2,100 |
| Invaded zone | 2,400 |
