Saturated Fluid Variation Effect on Seismic Anisotropy: A Case Study of Deep-Water Reservoir

Abstract Many factors can drive seismic anisotropy, whether it is the intrinsic condition of rock, external force, or longwave anisotropy. Saturated fluid, as one reservoir’s elements, known to trigger an anisotropic effect in far offset with Vertical Transverse Isotropic character. Anisotropy on presents hockey stick curving that a combination two-parameter could correct during move-out: V NMO and elliptical anisotropy η parameter. This research means observing how saturated fluid within reservoir contributes observed seismic. Rock physics modelling (RPM) substitution (FRM) are conducted investigate at particular temperature pressure reflects deep-water environment. The parameter extracted by applying Tsvankin 4 th Order obtain Based synthetic VTI Rüger Reflectivity, has manifestation η. In this case environment, gas sand needs most considerable correction, followed oil water-saturated. Although value difference relatively small easily dismissed insignificant, indeed does contribute
