High-resolution, multiscale, anisotropic hybrid tomography
Our 3D grid, multiscale, common image point tomography (CIP-tomo) provides you with industry-leading quality and resolution. Suitable for marine, land, and ocean bottom seismic geometries, CIP-tomo has a proven track record for producing detailed, accurate anisotropic earth models in the most challenging geological settings:
CIP-tomo is a generalized reflection tomography method that uses residual moveout (RMO, residual curvature) analysis of prestack depth-migrated CIP gathers to update an initial model. Multiparameter (nonhyperbolic, general, or nonparametric) RMO is automatically estimated from offset vector tile or angle gathers. The input model is a space-partitioned hybrid model representation that enables the isolation of different geologic units in the model space. This facilitates the application of geological and other constraints and the implementation of multilayer tomography. In addition, it supports the application of flexible weighting schemes. For challenging subsalt areas, CIP-tomo has the capability to update from migration scan input.
CIP-tomo is suitable for both compaction-driven (where velocity heterogeneity is dominated by a compaction gradient) and layered (where velocity heterogeneity is dominated by lithology or age) geologic environments. Its multilayer capability is flexible and enables inverting for property updates in specific layers or zones. It can account for transversely isotropic media and orthorhombic media with a vertical or tilted axis of symmetry, with different combinations of parameters updated as needed. Depending on the geology, data type (including converted modes), and anisotropy class, the most suitable tomographic inversion scheme can be applied to optimize results.
