Improving strategies with better seismic software
GGVeritas has launched BroadSource, its broadband marine seismic source. BroadSource is a natural complement for BroadSeis,
its industry-proven broadband marine seismic solution, to produce unrivalled images of the subsurface. BroadSource combines a synchronised
multi-level source with processing algorithms that fit seamlessly into the BroadSeis workflow to fill the source ghost notch. Tis innovative approach generates the same low frequencies as a deep-towed conventional source and extends the spectrum to higher frequencies, providing better resolution and clearer images of the subsurface. BroadSource reinforces the benefits of
BroadSeis to deliver what the company describes as the ultimate in high- resolution, broad-bandwidth, ghost-free seismic data, achieving a bandwidth of 2.5-200Hz. Te combination further improves BroadSeis image quality with a
sharper broadband wavelet which clearly resolves thin beds. Te best-in-class low-frequency content reveals geological details, such as layering and subtle facies and fluid variations, says the company. BroadSource has already seen successful pre-commercial deployment with impressive results for a BroadSeis survey conducted this summer for Lundin Petroleum in the Norwegian sector of the North Sea. Te new broadband source will be gradually deployed on the BroadSeis fleet on demand (Fig. 1). In a separate development, five months after CGGVeritas and Saudi Aramco signed a memorandum of understanding for collaborative R&D of geophysical acquisition, processing, analysis and interpretation technologies, the two companies have entered into a collaboration to conduct a major joint R&D project, known as SpiceRack, intended to herald a new innovative solution for seabed seismic acquisition. Under the terms of the SpiceRack
Fig. 1. BroadSource will be gradually deployed on the BroadSeis fleet .
