Petroleum Geo Services : PGS Improves Imaging Capabilities

This allows PGS to run larger jobs, image more complex data, while at the same time reduce lead time and get higher quality results. Our customers can take advantage of cutting-edge imaging algorithms such as PGS Reverse Time Migration, Separated Wavefield Imaging (SWIM®), and Wave Equation Reflectivity lnversion while at the same time reducing project duration in comparison to our competitors.

'We are very pleased to see the advances achieved by implementing the PGS advanced Imaging algorithms and workflows using the Cray supercomputers,' says Guillaume Cambois, Executive Vice President for Imaging & Engineering in PGS. 'Adding this second Cray XC system to our compute resources further raises our capability to solve our customers' geophysical imaging challenges faster, and more accurately.'

The computer is named PGS Galois after the French mathematician Évariste Galois (1811-1832), and comes in addition to the Cray XC supercomputer PGS Abel delivered last year.

Expanding its supercomputing platform allows PGS to continue to innovate and increase the Company's ability to further build on its industry-leading imaging inversion capabilities.

'Today's most advanced seismic survey datasets encompass many hundreds of terabytes, and gaining insight from this data lies squarely at the convergence of supercomputing and big data,' said Barry Bolding, chief strategy officer at Cray. 'The Cray supercomputers allow PGS to quickly process this data into an accurate, clear image of what's lying underneath the sea floor, through kilometers of varied geology. This is an extraordinarily complex computational challenge, and is where PGS excels. We're thrilled PGS continues to rely on Cray supercomputers to power the next generation of seismic processing and imaging.'
