Medium-term Pressure Transient Analysis performed in open-hole well with wireline pressure gauge.
Can be complemented by downhole fluid sampling with the same toolstring.
The key objective is to measure formation pressure and permeability at specified downhole locations.
It usually reaches the fully developed radial flow which allows assessing the effective reservoir thickness around a given well.
