Pressure Dependency & Seismo-Acoustic Signatures • The Stress sensitivity theory (Shapiro and Kaselow, 2005) describes the seismo-acoustic signature of pressure dependent rocks: V(P) = A + KP – B exp(-PD) A � the influence of lithology Ref.: Shapiro and Kaselow, K � the influence of the stiff pores Geophysics, 70/5 (2005), N27-N38 B and D � the influence of compliant pores • The seismo-acoustic signatures can help establishing a remote prediction of a pressure driven phenomenon, such as abnormal geo-pressure (over-pressure). • The seismo-acoustic signature of Ref.: Ciz et al., APPEA Journal , 2005, 449-457 temperature dependent rocks?
