Pore Pressure Prediction Using High-Resolution Velocities of Traveltime and Waveform Tomography

F036 Pore Pressure Prediction Using High-Resolution Velocities of Traveltime and Waveform Tomography N.M. AlBinHassan* (Imperial College London) & Y. Wang (Imperial College London) SUMMARY A predrill estimate of pore pressure can be obtained from seismic velocities using a velocity to porepressure transform but the seismic velocities need to be derived using a method having sufficient resolution for well planning purposes. One of the weaknesses of most of the pore pressure prediction methods is the limitations of the seismic velocities themselves. The velocity estimation from conventional stacking velocity analysis has limited resolution because of the signal-to-noise ratio of the gathers muting
