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  

Promax 2D Multiple Reduction

I am at a point, I could use some help with the program Promax 2D from Landmark Corp. I have posted in a LinkedIn group and this way I hope I may get some signal boost for my question. Do you have some experience with the following? Help a fellow Masters student out? I am […]

Miles vs Kilometer – Easy conversion with Fibonacci

Measurements are important. Even the little one’s want to know how much they grew in the past month. It’s a frame of reference. However, especially in geophysics we have not agreed on the same frame of reference. When you look at your data, you better make sure if it’s meters or feet or miles. It’s […]

Gain traction in the Geoscience community

The internet is a wonderful place. I am one of the lucky people who does not have to wait for weeks to get a hold of a paper I might need for my thesis. As a scientist this international network has become indispensible. Not just for retrieving papers, but also the review process and colaboration. […]
