Abstract

Summary

A Walkaround VSP (WARVSP) dataset has been acquired and analyzed to estimate the principal stress direction at the target formation, using various methods such as shear wave splitting analysis, Alford rotation analysis, and azimuthal amplitude analysis. As results of these analyses the different methods for determining the maximum stress direction concurred in the results and confirming the maximum stress direction in the field. WARVSP data also provided a qualitative characterization of the salt body shape around the well. This study recommend to combine different techniques to measure the principal stress directions and achieve characterization of a known presence of irregular salt bodies in geological complex fields.
