Vp/Vs Ratio from Three Component Zero Offset: An Additional Tool for Pressure Prediction Ahead of the Bit

Risk reduction is an important matter for exploratory wells. Pre-drill pressure forecasting is<br>usually performed from seismic derived velocities, offset well information and basin fluid flow<br>modeling. Still there is a significant uncertainty level about the stress regimes ahead of the bit;<br>therefore it is necessary to refine the estimation of pore pressure ahead of the bit.
