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.

Gas Hydrates - Part V: The Resource Potential

The gas hydrate resource is a function of geology, technology, policy, and market conditions. As we have seen, the commercial resource and recovery potential of gas hydrate strongly depends on the type of gas hydrate accumulation. In Part V of our series on gas hydrates, we discuss the resource potential.

Broadband Seismic Technology and Beyond Part IV: PGS’s Geostreamer – Mission Impossible

In 2007, PGS took the industry by surprise with the launch of the GeoStreamer, the dual-sensor towed streamer that kick-started the broadband revolution. But how did they solve the riddle of combining the hydrophones and geophones into broadband measurements? For most geophysicists, it was seen as ‘a mission impossible’. It turned out to be so simple, so elegant, and so brilliant. It was a fantastic journey, of course with setbacks, but with persistence, a culture of innovation, and outstanding geophysical work, they won. Their achievement represents maybe the largest single step in the technological development of the marine seismic streamer.

Broadband Seismic Technology and Beyond - Part III: The Interaction Between Ocean Waves And Recorded Seismic Data

Broadband seismic technology is designed to reduce the influence of the ocean waves on seismic data. To understand and appreciate this, we need an understanding of the interaction between the mighty ocean and the seismic streamer beneath the ocean surface. How quiet is life below the waves?
