One way is to split well tests into two major categories:
Pressure Testing |
---|
Flowmetering |
---|
DST – Drill Stem Test |
SBT – Separator Bulk Test |
WFT – Wireline Formation Test |
Surface Multiphase Flowmeter | |
SGS – Static Gradient Survey | Downhole Multiphase Flowmeter |
PTA – Pressure Transient Analysis |
The other way is to split well tests by data acquisition methodology into three categories:
...
Single-Well Tests | Multi-Well Tests |
---|---|
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 | PTA – Pressure Transient Analysis|
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) |
