Reservoir pressure variation in time and space in response to production / injection activity
The popular classifications are summarised 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 the pressure diffusion processes honor PDE with constant coefficients which reveals opportunities to very efficient mathematical and diagnostic engines:
Time Convolution | Spatial Superposition |
Pressure convolution model | Pressure superposition model |
Pressure deconvolution model | Pressure decomposition model |
