Real-Time Elastic Earth Model Estimation for Pore-Pressure Prediction Ahead of the Bit

D016 Real-time elastic earth model estimation for pore-pressure prediction ahead of the bit Abstract * Mark of Schlumberger. th EAGE 67 Conference & Exhibition — Madrid Spain 13 - 16 June 2005 1 Abnormally high formation pore pressure is one of the major problems facing the exploration drilling industry especially in deep waters. Estimation of pore pressure before drilling (predrill pore-pressure prediction) is typically performed from surface seismic data. This prediction however is only as accurate as our ability to estimate the velocities in the region of interest which could be many thousands of feet deep. While the well is
