Geopressure Prediction and Analysis in Deepwater Gulf of Mexico Using Rock Physics and Seismic Attributes

A-23 GEOPRESSURE PREDICTION AND ANALYSIS IN DEEPWATER GULF OF MEXICO USING ROCK PHYSICS AND SEISMIC ATTRIBUTES Abstract 1 N.C. DUTTA¹ S. GELINSKY² M. KHAN ¹ Z. ZHENG² ¹Baker Hughes - Western Geophysical PO Box 2469 Houston TX 77252 USA ²Baker Hughes – Baker Atlas Deepwater drilling is risky and expensive. Proper well planning requires reliable estimates of pore fluid pressure prior to drilling. While drilling monitoring and frequently updating these estimates guarantees environmentally safe drilling. Most common practice to predict pore pressure is to use conventional seismic stacking velocities as porosity indicators in conjunction with a Normal Compaction Trend (NCT)
