Specific type of Production Analysis (PA) workflow based on correlation between single-well or multi-well production/injection history and BHP.
The key assumption of FMB is a pseudo-steady state correlation between cumulative offtakes/intakes and BHP dynamics.
It does not require new data acquisition at well site and makes use of existing dynamic data records.
There are two major engines of MatBal analysis:
| MatBal Pressure @model |
| Formation pressure model only |
Objectives
| Check if the field is under volume-constrained production (PSS) |
| Assess drainage volume |
| Assess reservoir compressibility |
| Check if water and gas propagation match uniform sweep model |
| Verify oil/gas FVF |
