The actual petroleum reservoir is always constrained in volume (usually by seal and and a cap rock).
But in some practical applications the observation time is too short to see the effects of the reservoir boundaries.
In this case a reservoir flow can be analytically modeled with infinite boundary reservoir:
| Linear Flow | Radial Flow | ||||||||
|---|---|---|---|---|---|---|---|---|---|

Numerical model always performs calculations with finite boundary.
