... The well-known “Biot-Gassmann” formula for the difference between “undrained” and “frame” compressibilities of rocks is in error. The error was introduced by Gassmann (implicitly revising earlier work by Biot), and results in an expression which is simpler than Biot’s equivalent expression...

... a wave-equation-based AVO inversion (WEB-AVO) that solves for the full elastic wave equation; the total wavefield in the object domain, as well as for the underlying elastic properties: the compressibility (1/bulk modulus) and the shear compliance (1/shear modulus). This inversion is expected to resolve...

Internal multiple scattering, transmission effects and mode conversion, considered as noise in linear inversion, become essential signal in WEB non-linear inversion; accordingly, WEB compressibility showed increased...

... pressure increase is solved based on the compressibility and volumes of pore space and pore fluids. Our modeling results agree that the evolution of organic shale’s rock-physics property during kerogen maturation is consistent with fluid expansion model that sonic velocity decrease while density changes...
