• PGS offers depth imaging solutions for all marine seismic data
• Our solutions are viscoacoustic, anisotropic and produce prestack gathers
• Our PSDM algorithms supply densely sampled angle gathers as well as conventional offset gathers
• We improve shallow imaging and subsurface characterization by harnessing sea-surface reflections and multiple energy
• All marine seismic data, for all geometries can be imaged using Kirchhoff and wave equation-based depth migrations. Our solutions generate fully AVA-compliant prestack gathers for subsurface characterization.

All marine seismic data, for all geometries can be imaged using Kirchhoff and wave equation-based depth migrations. Our solutions generate fully AVA-compliant prestack gathers for subsurface characterization.

Our reverse time migration (RTM) wave propagation engine is common to FWI, PGS Ultima, separated wavefield imaging (SWIM), and full wavefield migration (FWM) for simultaneous imaging of both multiples and primaries. PGS also has a comprehensive suite of least-squares migration (LSM) solutions for target-specific challenges.

PGS depth imaging solutions can be extended to accommodate FWM and SWIM to improve the imaging illumination, mitigate acquisition footprint, reduce the crosstalk, and produce an enhanced shallow image of the earth’s reflectivity.

For simultaneous updating of both velocity and reflectivity models, PGS Ultima combines both FWI and LSM into a single solution.
