Specific Pressure and Flowrate measurements with a purpose to analyze wellbore pressure response to flowrate variation in order to assess reservoir, well-reservoir contact and wellbore storage properties.
One of the two branches of Well Testing where static or dynamic pressure is the key element of analysis.
| Open-Hole (OH) | Cased-Hole (CH) | ||

| DST – Drill Stem Test | WFT – Wireline Formation Test | Cased-Hole Pressure Transient Test | SGS – Static Gradient Survey |
The interpretation methodology of the pressure tests is called Pressure Transient Analysis (PTA).
