Part of Well & Reservoir Surveillance and one of the Subsurface E&P Disciplines,
related to measuring well volumetric flow rate and wellbore pressure in one or few selected wells and analysing pressure-rate correlation.
The quantitative interpretation is based on pressure diffusion model.
There are different well tests classifications.
One way is to split well tests into two major categories:
The other way is to split well tests by the location where the measurements are taken and the well completion status:
Third way is to split well tests by number of wells involved:
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) |
