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 […]

My Interview with the EAGE about the Way of the Geophysicist

The European Association of Geoscientists and Engineers (EAGE) interviewed me. It appears in the 2015 edition of their student newsletter. My fellow students already asked me about it and now you can read it online! I enjoyed talking in the interview with Kirsten Brandt and I do hope more opportunities like this may arise. Interview: Blogging his way […]

Seismic Image with Hydrocarbon Indicator Interpretation

The subjective science of seismic interpretation

The final step in the work with seismic data is seismic interpretation. In a scientific field called geophysics, interpretation sounds highly subjective; Very different from the usual statistics, ray and wave phenomenae. This can’t be right, right? I’d love to say it’s very clear and seismic data reveals a perfect image of the subsurface. But […]

New on StackExchange: Temporal Resolution of Seismic data

Radius of the Fresnel zone is given by [math]Rf=(v/2)(t_0/f_\mathrm{dom})^{1/2}[/math] where v: velocity of layer [math]t_0[/math]: two way travel time [math]f_\mathrm{dom}[/math] :dominant frequency in the spectrum This shows that high frequencies give better resolution than lower frequencies and resolution deteriorates with depth and increasing velocities. However I found some text in “Seismic Data Analysis- Yilmaz” which […]

Do we even need math? – Calculus in geophysics and geology

The amount of calculus in geophysics and geology degrees varies throughout every university and even in uni itself, there seldomly is a consensus on how much math is actually needed. Jascha Polet from Cal Poly Pomona asked a very interesting question on Twitter: Should every student who graduates from a Geology (not Env Sciences) MSc […]

Lifesavers – Two tools in my daily worklife

Today I’d like to share two tools that I have found indespensible in the course of my studies. Ironically, these have nothing to do with geophysics or seismic at all. But they’re out to save you. Git Git is a very low-key version control tool. At certain points in the process of creating you can […]

Lying with statistics

Lying with statistics.

You can see it quite often today, that an essential part of an axis is missing. I usually think highly critical of not showing your entire plot. Finally someone has made the appropriate visualization about lying with statistics. Baseline matters via Flowing Data from Reddit
