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 […]
