One of the Subsurface E&P Disciplines, related to long-term analysis of production/injection history and its correlation with bottom-hole pressure measurements and/or formation pressure from well tests.
The key objectives of PA is to predict the flowrate and its components (water cut Yw and gas-oil-ratio GOR) in response to other dynamic variables.
Unlike well tests which normally last for few hours or few weeks, PA usually covers a time period from few months to many years.
PA is split into following categories by objectives:
| Well Flow Performance (WFM) | Watercut Diagnostics | Waterflood Diagnostics | Reservoir Diagnostics |
|---|---|---|---|
| Productivity Diagnostics | GOR Diagnostics | Gasflood Diagnostics |
into three categories by the mathematical methodology:
| Empirical Production Data Analysis | Statistical Production Data Analysis | Physical Production Data Analysis |
|---|
and into following categories by the available of inputs:
