Real-time Pore-pressure Prediction Ahead of the Bit

In this article, we combine the prediction capability of seismic data with the actual measurements of the real-time logs to accurately predict pore pressures to thousands of feet deeper than the bottom of the well.

Summary:In this article, we combine the prediction capability of seismic data with the actual measurements of the real-time logs to accurately predict pore pressures to thousands of feet deeper than the bottom of the well. We use the new LWD tool called seismicVISION that provides real-time checkshot measurements while the well is being drilled. We also use all available realtime logs, such as P- and S-wave sonic and density, and calibrate them by the seismicVISION checkshot data.
