Seismic images of Earth's subsurface are essential for oil and gas exploration. Gaussian
beam migration is popular for seismic imaging owing to its flexibility and efficiency of …

Reverse time migration (RTM) is a well-established imaging technique that uses the two-
way wave equation to achieve high-resolution imaging of complex subsurface media …

Least squares reverse time migration (LSRTM) imaging is the one of the most accurate
methods for migration imaging at present, and Polak–Ribiere–Polyak conjugate gradient …

Wavefield decomposition can be used to extract effective information in reverse time
migration and full-waveform inversion. The wavefield decomposition methods based on the …

This paper proposes a novel technique to handle the wavefield domain involved in the
procedures of seismic modeling, reverse-time migration (RTM), and full-waveform inversion …
