World’s Largest Multi-Client 2D Seismic Library On 1st July 2015, Spectrum more than doubled its seismic library through an agreement to buy Fugro’s Multi-Client data sets. Spectrum now holds the world’s largest 2D library of seismic, totaling over 3.3 million km, and a significant volume of 3D data. This Multi-Client seismic covers all major sedimentary basins across the globe with unique, wide-ranging 2D and 3D coverage offshore Brazil, N.W. Australia, Norway and in the Barents Sea. Our team of geoscientists are continually examining the data to discover new plays and prospectivity, identify reprocessing opportunities as well as develop new surveys.
