Figure 2.17. Pore pressure estimation from seismic reflection data along an E–W seismic line in the<br />

SEI-330 field (after Dugan and Flemings 1998). (a) Stacking, or RMS, velocities determined from<br />

normal moveout corrections. (b) Interval velocities determined from the RMS velocities. (c) Pore<br />

pressures inferred from interval velocity in the manner discussed in the text.
