Field systems02Why GEOGALS
Clusters are placed in a specialised area with high safety regulations. Through the years we have found partners to increase compute resources up to 5,000 CPUs within one hour.
Read moreGEOGALS® produces standalone software for seismic operations QC and project recovery. 32 QC displays, built together with OPS, OBS, NAV and GUN specialists. Recent experience — 3D geometry recovery for 20-year-old data.
Read moreMaintaining the amplitude–frequency characteristics of the signal is one of the critical conditions for reliable kinematic and dynamic interpretation. Our specialists employ flexible adaptive noise attenuation that preserves the original distribution of amplitudes and frequencies.

Marine processing tools offer an extensive range of capability for any marine seismic processing task. This starts with the option to perform real-time QC onboard a seismic vessel, 2D SRME and PSTM, while for those looking to get the most from their marine data we also offer advanced marine and depth imaging options. The advanced marine package includes the latest de-ghosting and 3D SRME tools to extract the highest value from your conventional or broadband data.
REAL PHOTOWorking together, our acquisition and processing teams provide you with the highest quality seismic data and fast-track deliverables for every type of survey and for every type of acquisition technique.
Specialists and resources are chosen according to the project timeline and are never shared between projects. For time optimisation, further processing steps are started as soon as possible and run in parallel. The client is always given an option either to get results earlier, or to have extra products and recommendations.
