Specific type of Pressure Tests performed in open-hole well across the formation unit isolated by packers (see Fig. 1).
The usual duration is dozens of hours which is in most cases enough to capture the response from the whole effective flowing thickness and assess reservoir transmissibility.
The key objective is to assess formation pressure, reservoir transmissibility and skin-factor in target reservoir.
Can be complemented by downhole fluid sampling with the same toolstring.
