... characterization. However, one should first understand the meaning of FDR amplitude in terms of elastic properties. In theory, FDR, which is derived from the FWI velocity, should be a derivative response of velocity, and a P-wave sonic log should be used to calibrate FDR before interpretation. While elastic FWI...

.... Introduction Coloured inversion (CI) combined with extended elastic impedance (EEI) calculation is well-known as a fast means of obtaining band-limited estimates of elastic properties from seismic AVA data. The coloured inversion process partially increases the bandwidth over the seismic data, notably...

.... In this paper, we combine the stress-induced anisotropy theory and the fracture equivalent medium theory to analyze the effect of BCD in the elastic properties of the shale oil reservoir formation. This model is applied to the real log data of the study area. The in-situ BCD is recovered, and it is used...

... The study explores a model for the interaction of carbon dioxide with ultramafic rocks, aiming to assess how carbonation impacts rock elasticity in applying CO 2 sequestration. We utilized a cellular automata-like algorithm to evaluate how carbonation alters the elastic properties of the host...

... The amplitudes of depth-migrated seismic data can be biased by uneven illumination in the presence of complex geology and/or limitations of the acquisition geometry. If not accounted for, the imprint of non-geological illumination variations compromises acoustic or elastic properties estimated...

... computational speed-up factor compared to the elastic inversion of the original dataset. We demonstrate the efficacy of the proposed technique by estimating the elastic properties of a potential hydrocarbon prospect located on the flank of a salt diapir. The retrieved elastic properties are then used...

... The elastic properties of clay in shales can be derived from a simple model consisting of domains of partially aligned anisotropic clay platelets embedded in a softer interplatelet medium representing clay-bound water and interparticle contacts. Approximating clay platelets as ellipsoidal...
