Noise CC-BY Kevin Dooley

What’s with the noise?

We often only look at reflection data in a stack. But, along the way a lot of “noise” has been processed out of the seismic data to chisel out the “signal”. It’s all about signal against noise. However, one person’s noise may just be another person’s signal. Let me elaborate. If you’ve been around during […]

Challenges in Machine Learning

Geoscience and Machine Learning – EAGE 2017 Workshop

Is it data science? Machine learning? Big Data? Deep learning? Fancy math? Or just chalked up statistics with enough data? This Monday marked the start of the EAGE 2017 in Paris for me. If you have read this blog or the EAGE Student Newsletter before, you may have seen that I am some sort of […]

What is 4D seismics?

4D seismics is hype. It’s the new stuff. But 4D is also somewhat obscure, so when I started telling people telling that I had landed a job in 4D seismics, the most common question was: So, Jesper, what’s the fourth dimension. The answer always causes some disappointment. “It’s time.” They were hoping for some obscure […]

Cascading Earthquakes – Seismic waves can trigger another earthquake

Earthquakes teach us about the interior workings of Earth. Without them, we would not know about the core or any layering deeper than a couple kilometers. Researchers from the Los Alamos National Laboratory, MIT and Earthquake Research Institute Tokyo have now proposed a new triggering mechanism for earthquakes. Triggered earthquakes happen due to a certain […]

Geophysyfus - A geophysicist doing always repeating their task.

Geophysyphus

Here at the way of the geophysicist. We love neologisms. How do you like this one?   The Story of Sisyphus Sisyphus is a figure from Greek mythology. He was a pretty smart fellow, tricking death several times. However, in the end he is punished with the eternal task of pushing a boulder up a hill. […]

Code your way to the Common Reflection Surface

Build a Common Reflection Surface Workflow in 6 easy steps

This article aims to be an in-depth article about building a workflow suited for proper use of the Common Reflection Surface. This resource is aimed at a specialist audience, however maybe this is a rare insight into the intricacies of seismic processing for some of our readers. The processing package for CRS is often regarded […]

Rethinking the Common Reflection Surface Processing Tool

I worked with the seismic processing algorithm Common Reflection Surface for the past years. During this time I have come to the following conclusion: CRS has a marketing problem. I have worked with CRS in university, at Fugro Seismic Imaging and Wester Geco, respectively Schlumberger. Its development is closely tied to advanced concepts like the […]
