... 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...

Over the pressure ranges we model these effects are assumed to be minor. Forchheimer terms are also assumed negligible due to...

... of compaction depends on the magnitude of the pressure drop and the compressibility of the reservoir rock. Conversely, a pressure increase during injection will cause the reservoir to expand. These changes at the reservoir level propagate into the overburden causing it to deform too. However, the...
