Case study


One of the Largest ever Marine 3D Projects

One of the largest 3D proprietary marine seismic projects ever (29,322 square Kilometre project) offshore Colombia, shot in 2 phases, an area equal to 1,258 GoM lease blocks!

The project utilised the latest Broadband acquisition techniques on the CGG vessels Oceanic Sirius and Oceanic Vega, and so required top of the line QC expertise, as well as highly effective environmental monitoring capabilities to ensure Colombian regulations were adhered to.
