It can be challenging to pick high-quality first arrivals on noisy seismic data sets. The stability and smoothness criteria of the picked first arrival are not satisfied for data sets with shingles and interference from unexpected and backscattered e

Diffraction imaging can increase the spatial resolution of seismic images beyond conventional means to provide interpreters with high-resolution structural and stratigraphic sections. The reflection image of a specular reflector only exists in either

We have developed an efficient and practical wave-equation-based technique to image subsurface geologic features such as isolated scatterers, reflector edges, fault, fracture zones, and erosion whose information is mainly contained in diffracted wave

An intrinsic problem during migration and imaging of seismic wavefields using the two-way wave equation is the crosstalk interference between the up/down propagation of the corresponding source and receiver wavefields. To mitigate this crosstalk, the

The key objective of an imaging algorithm is to produce accurate and high-resolution images of the subsurface geology. However, significant wavefield distortions occur due to wave propagation through complex structures and irregular acquisition geome

Over the last few years, machine learning has become more and more a topic of interest in the seismic industry. In seismic interpretation like fault/salt dome detection (Amin et al. 2015, Guitton et al. 2017) and velocity picking (Smith 2017), there

Summary An efficient and practical wave-equation-based technique is proposed to image subsurface geologic features such as isolated scatterers, reflector edges, faults, fracture zones, and erosional boundaries whose seismic expression is mainly chara
