SeaSCAN Seismic

SeaSCAN Airgun Typical Source Array Applications.

SeaScan has the flexiblity to quickly design, fabricate, and test special marine seismic source client requirements. Our role as a service provider in the exploration sector varies greatly depending on our clients needs. Seascan has the experience and resources to provide everything from a highly portable modular shallow water tuned array, used in the shallow water theater with emphasis on OBC and transition zone work, to an all inclusive shooting package to include platform, navigation, geophysical equipment and personnel for use in deeper water arenas.

Time Lapse Seismic: 4D is emerging as a key technology to move seismic techniques from Exploration to Production. Over 100 4D projects are currently in progress, mostly in the marine environment, with more projects starting every month.

Vertical Seismic Profiling: New down-hole sensor technologies are creating new interest in VSP technologies to aid in detailed Reservoir Characterization.

High Resolution Imaging: 2D and 3D high resolution imaging is increasingly being applied to verify the near surface stability of the water bottom for expensive offshore construction, and to allow the planning of wells to avoid dangerous shallow water flows and near surface gas pockets.

Shallow Water & Ultra Shallow Water Seismic: New seismic technologies, including remote storage and multimode recording electronics are allowing cost effective application of 2D and 3D in shallow water ‘transition zone’ areas that have previously been considered as ‘no go areas’ for traditional seismic methods.
