3D/4C EMILIO: A multi-component survey for fractures characterization

The Emilio 3D/4C ocean bottom cable survey in the Adriatic Sea was designed to acquire wideazimuth<br>data and processed to detect azimuthal anisotropy for fracture characterization in the carbonate<br>reservoir. Exploiting the high and uniform fold of coverage in each offset and azimuth range, separate<br>volumes for the different wave-field propagation directions were produced: four PP-wave and sixteen PSwave<br>restricted azimuth datasets. Valuable anisotropy information was derived from pre- and post-stack<br>analysis of all these volumes. Analysis of PP and PS amplitudes and results of PS layer stripping at the target<br>were crosschecked to bore-hole information and well data production.
