Prediction and 3D Imaging while Drilling by Drill-Bit 3D RVSP

P221 PREDICTION AND 3D IMAGING WHILE DRILLING BY DRILL-BIT 3D RVSP Abstract 1 3D imaging by drill-bit SWD data was successfully demonstrated in a first survey performed in Sicily (Italy) in 2000. However in this first survey the final 3D imaging results were achieved only after the well was completed. Following the experience of this pilot survey a second 3D RVSP was acquired in another exploration well drilled in Southern Apennines (Italy) in 2002. In this work we present the 3D imaging results obtained and used for prediction while drilling in the new 3D drill-bit RVSP application. The goal of
