Specific type of Production Analysis (PA) workflow based on correlation between single-well or multi-well production/injection history and field-average formation pressure estimateIt may also include BHP pressure data records if they are available and were varying over time.
In cae of multi-tank analysis
The key engine assumption of MatBal is a pseudo-steady state correlation between cumulative offtakes/intakes and and formation pressure dynamics (see MatBal Pressure @model) 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 | MatBal Flow @model |
| Formation pressure model only | Formation pressure and flowrate model |
In some cases a similar analysis can be performed using the correlation between production/injection history and BHP which is called Flowing Material Balance Analysis (FMB).
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 |
