- One Drawdown transient response (DTR) for the PDG well which characterises the pressure response of the PDG well to its own rate variation
- N – 1 cross-well transient responses (CTR) for the interval between PDG and each of the N –1 surrounding wells and which characterises the impact the surrounding wells provide on the formation pressure in PDG well

This set of information represent a high value for reservoir engineers for daily planning and also valuable for simulation engineers for 3D model calibration.
The weakest point of RDCB is its inability to distinguish the contour button off two (or more) wells which were changing its rate synchronously (or did not change it at all) during the whole time of the PDG recordings.
