Seismic imaging system that successfully handles challenging subsurface complexity
EarthStudy 360 maximizes the information that can be extracted from recorded seismic data. The wealth of seismic image data is decomposed into full-azimuth, angle-dependent reflectivities and directional (dip and azimuth) data components. These components can be selectively sampled, creatively combined, dynamically visualized, and further processed to secure images of the subsurface.
EarthStudy 360 Features:
Optimal imaging system that successfully handles challenging subsurface complexity (illumination, complex wave phenomena, VTI, TTI, orthorhombic anisotropy, Q compensation)
Specular imaging options to enhance reflections in poor signal-to-noise or illumination conditions
Diffraction imaging options to reveal geological discontinuities such as faults, point diffractors, channels, etc.
Full-azimuth anisotropic tomography honoring seismic, well and geological constraints, resulting in optimal geophysical models with reduced uncertainty.
Accurate, high-resolution amplitude inversion for reservoir properties analysis, stemming from true amplitude migration
Full-azimuth residual moveout and amplitude inversions for fracture and stress determination
Sophisticated illumination QC tool for deeper insight.
Full portfolio of 3D azimuthal gather post-processing options.
EarthStudy 360 Benefits:
Construct accurate kinematic and dynamic subsurface images from recorded surface seismic data, using the full seismic wavefield
Provide high-resolution images, which lead to the detection of faults, fractures, and small vertical displacements in reservoirs, especially important in unconventional shale plays
Obtain optimal information for anisotropic tomographic solutions as well as true amplitude reflectivities for AVAZ
Avoid surface azimuthal sectoring
Generate the highest directional sampling from the seismic method
Reduce seismic velocity non-uniqueness with continuous azimuthal sampling
Enrich subsurface illumination information from all angles and all azimuths
Detect angle-dependent azimuthal anisotropy to determine orientation and spatial characteristics of heterogeneously distributed, sub-seismic, fine fractures
Apply specular weighting to enhance structure continuity, or attenuate specular energy (diffraction imaging) for enhancing discontinuous objects such as small faults and fracture systems
Gain broader insight into elastic properties and boundaries of target reservoirs
Generate rich and detailed seismic reservoir images for difficult-to-interpret 4D seismic signals
Improve performance through lateral and vertical variable sampling, with no effect on data quality
