PGS further strengthened one of the most powerful computer platforms in the oil service industry by adding another Cray XC supercomputer to its Houston Mega Centre.

The company said this will allow it to run larger jobs, image more complex data, while at the same time reduce lead time and get higher quality results.

“We are very pleased to see the advances achieved by implementing the PGS advanced Imaging algorithms and workflows using the Cray supercomputers,” said 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.

“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 kilometres 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.”
