Supercomputers for Beginners - Part III. GPU-Accelerated Computing

Many TOP500 supercomputers today use both CPUs and GPUs to give the best of both worlds: GPU processing to perform mathematically intensive computations on very large data sets, and CPUs to run the operating system and perform traditional serial tasks. CPU-GPU collaboration is necessary to achieve high-performance computing.

Broadband Seismic Technology and Beyond PART VII: CGG’s BroadSeis - A Change of Thinking

As geophysicists, we learnt and believed that seismic deghosting through ghost notches in pressure-only recordings was impossible when the sensors were deep. CGG changed that way of thinking. Instead of fighting the ghost in acquisition, they made a different set of rules to fully exploit ‘notch diversity’ in data processing and imaging.

Broadband Seismic Technology and Beyond PART X: IsoMetrix - Isometric Sampling

IsoMetrix is more than broadband seismic. It goes beyond, by reconstructing the deghosted wavefield in 3D, and performs fine spatial sampling in all directions. In this article we ask: how did the idea come about? What is the story behind a ten-year R&D project in Schlumberger – its largest single engineering investment ever? The result was a great innovation: IsoMetrix, a technology that can ‘read between the streamer lines’. The project not only delivered the new seismic acquisition technology, but also the algorithms and workflows needed to manage the unprecedented amount of data it produces.
