Pore Pressure Prediction

Pore pressure prediction from seismic velocity data is inherently uncertain. The uncertainty can be significantly reduced by using a coupled geological-velocity model, calibrated by geological and drilling data.


Pore pressure prediction requires optimal velocities.

Offset well data generates normal compaction curve and estimates pore and fracture pressures.

Geological pressure model assesses relationships between shales and reservoirs at wells.

Calibrated 2D and 3D seismic interval velocities used to create pore pressure, overpressure, overburden and fracture pressure volumes.

Seismic data is calibrated to sonic/VSP/checkshot data.

Volumes interrogated to judge their ‘reality’:

• Is overpressure distribution plausible?

• Does it match likely mechanism(s) and rock properties?
