Unlike production analysis which normally covers a time period from few months to many years, well tests are rather short and normally take from few hours to few weeks.
The quantitative interpretation is based on on:
...
- model with a purpose of dynamic reservoir properties analysis
- well completion model with a purpose of Leak Detection
...
There are different ways to classify the well tests classifications.
One way is to split well tests into two major categories:
...
PIST – Pressure Interference Step Test (as version of PTA) | |
PICT – Pressure Interference Pulse Test (as version of PTA) | |
| DST – Drill Stem Test | |
| WFT – Wireline Formation Test | |
| Drawdown Test (DD) (as version of PTA) | |
| Injection Test (INS) (as version of PTA) | |
| Build-up Test (BUS) (as version of PTA) | |
| Fall off Test (FOS) (as version of PTA) | |
MRST – Multirate Step Test (as version of PTA) | |
SPT – Self-Pulse Test (as version of PTA) |
