Specific type of Production Analysis (PA) workflow based on correlation between single-well or multi-well production/injection history and field-average formation pressure
It may also include BHP pressure data records if they are available and were varying over time.
The key engine of MatBal is a pseudo-steady state correlation between cumulative offtakes/intakes and formation pressure dynamics (see MatBal Pressure @model).
It does not require new data acquisition at well site and makes use of existing dynamic data records.
Objectives
| Check if the field is under volume-constrained production (PSS) |
| Assess drainage volume |
| Assess reservoir compressibility |
| Verify oil/gas FVF |
