Seismic I/O, Open Source, and Deep Double Descent – Friday Faves

This week in our Friday Faves, we have a new Python package for seismic compression and input/output, a conversation on the merits and caveats of open source and the confirmation that more data sometimes hurts machine learning models. Seismic Compression and I/O Equinor anounced the Python version of a compression algorithm for seismic data that […]

SEG-Y sucks! Or does it?

Many a times I have been cursing, when I got a new seismic file. Be it a 2D line, 3D cubes or pre-stack data, the standard is seldomly adhered to by most companies. The Standard SEGY as defined by the standard is now in revision 2. Most standards will likely be rev1 in these days. […]

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 […]

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 […]

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 […]

Seismics Introduction

We send sound into the ground and listen what comes back to the surface. There are a lot of sources we can use to make this sound. A very basic but effective approach is to use a sledgehammer and bang it on a steel cap on the ground. This works well to get some acoustic […]
