Seismic diffractions are weak seismic events hidden within the more dominant reflection
events in a seismic profile. Separating diffraction energy from the poststack seismic profiles …

The seismic wavefield arises from interactions of a source wavefield with subsurface
heterogeneities as the wavefield propagates through the earth. In a conventional seismic …

Instead of dismissing seismic diffractions as interfering noise and ignoring or suppressing
them, they can be used to identify small geological discontinuities such as faults, dykes, and …

We present a 3D diffraction imaging procedure with the subsequent computation of
diffraction attributes and their application in field seismic data processing. This procedure …

Knowledge of the spatial distribution of subsurface fractures is critical for improving the
production of geothermal and oil/gas. The double-beam (DB) method using acoustic waves …

Diffracted wavefield carries high-resolution information about subwavelength geological
structural elements crucial for imaging small-scale subsurface discontinuities. However, the …

Under the influence of coal mining, the gravel in mining tunnel sections of a fault fracture
zone is prone to collapse, and the collapse accumulation body will block the tunnel, which …

The paper presents the high-performance implementation of the target-oriented 3D seismic
imaging procedure. The migration algorithm uses individual Gaussian beams for focusing …

The efficiency of the development of an oil and gas field is largely determined by the
knowledge of its geologic structure. In the recent decade, complex fractured carbonate …
