The popular classifications are summarized below:
| Number of phases | Number of wells | Solver type | Spatial dimension |
|---|---|---|---|
| Single-phase | Single-well | Analytical Linear | 0D |
| Multi-phase | Multi-well | Analytical Pseudo-Linear | 1D |
| Numerical Linear | 2D | ||
| Numerical Non-Linear | 3D |
In many practical cases a pressure diffusion process is honoring some PDE with constant coefficients availing a number of very efficient computational and diagnostic techniques:
| Time Convolution | Spatial Superposition |
|---|---|
| Pressure convolution model | Pressure superposition model |
| Pressure deconvolution model | Pressure decomposition model |
There is a number of specific pressure diffusion models which represent the key practical scenarios of pressure diffusion and play important academical and practical role:
