Abstract
The interpretation of geophysical and mechanical rock properties is essential for subsurface characterization, reservoir modeling and future development. This work focuses on the Central-Eastern Italy and Adriatic offshore areas, exploiting a publicly available well log database. Sonic logs (DT logs) were digitized and processed using Schlumberger Petrel software (v2013) to derive compressional-wave velocity (Vp) and shear-wave velocity (Vs) through empirical equations. The geophysical properties together with a derived density log were used for Dynamic Elastic Moduli (Young’s Modulus) calculation for the above region. Correlation between wells was performed to investigate relations between lithology and geophysical and mechanical parameters. During the log analysis it was selected a potential interval suitable for CO2 storage for which was performed a preliminary storage capacity calculation.
The results show consistent correlations between seismic velocities and mechanical parameters
