In 2008 the Optowave fibre-optic seismic sensor cable was trenched at the StatoilHydro-operated Snorre field with the aim of achieving insight into installation, data acquisition and monitoring procedures. The Snorre pilot demonstrated ‘real time' data transfer and quality control - the fundamental requirement for reservoir monitoring ‘on demand'.
Part I: The Drive For Better Bandwidth And Resolution
Once a new technology rolls over you, if you’re not part of the steamroller, you’re part of the road. One such technology is broadband seismic. Want to be part of the steamroller or the road? In a series of articles, we give you an introduction to what broadband seismic has to offer.
Most oceanic gas hydrates are mapped using seismic data. How much do key seismic parameters vary from a hydrate rock to a water-saturated rock? Should the hydrate be considered as part of pore fluid fill or a part of the rock itself? To answer such questions, we need to understand the rock physics of sediments containing gas hydrates.
Scientists have known and studied natural gas hydrates for decades. Vast deposits of hydrates have been found, both in the permafrost and the continental shelves of the oceans of the world. Natural gas hydrates also exist in the universe. Hydrates have played an important role during formation of planets, and our atmosphere and hydrosphere. Want to know more? Read on!
Of the 31,900 species of fish living today we know that more than 1,000 make sounds, ranging in frequency from 50 to 8,000 Hz. For most fishes, the sonic mechanism is a muscle that vibrates its swim bladder not unlike our vocal cord. For many other species, the sonic mechanism remains a mystery.

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.
