Seismic processing software
One platform from field tape to depth image.
g-Platform is a complete 2D/3D/4D/VSP seismic processing and imaging system — geometry & QC, statics, denoise & demultiple, deconvolution, 5D interpolation, time imaging, anisotropic depth imaging (PreSDM, RTM/FWI) and VSP — with GPU acceleration and HPC cluster scaling.
Every processing stage. One environment.
From field-tape geometry to anisotropic depth images and VSP — production-grade algorithms across the entire workflow, all on a single platform.

License exactly what your survey needs.
Time Imaging is delivered in four packages — so acquisition crews, land and marine processors, and full-chain shops each get the right module set. Depth Imaging and VSP are available as their own packages.
Geometry and data quality control in the field or onboard — data loading, nominal geometry handling and QC.
Full refraction & residual statics, SC amplitude correction, and AGRA adaptive ground-roll attenuation for land time imaging.
Vessel-speed / receiver-motion / tidal statics, deghost / designature / debubble / SRME (true azimuth) and swell-noise tools.
All modules across land and marine, including Kirchhoff Pre-STM with ETA anisotropy / OVT and PSTM angle-stack imaging.
Universities & research institutions: g-Platform is free for teaching and non-commercial research under the Academic License Program.
