Dipping your Toes – Machine Learning for Geoscientists

My fellow students know this and I hope recruiters will never read this: I was never good at math in university. It was only later when it came to the application in actual geophysical problems that tensors, linear algebra, and differential equations clicked. Personally, I don’t recommend this, as it makes life unnecessarily hard. Machine […]

Getting started with the SEG Machine Learning contest

The Society for Exploration Geophysicists (SEG) started a contest to predict facies from wireline logs via machine learning. Get your Buzzword Bingo cards ready, we’re about to dive deep. The October 2016 issue of The Leading Edge had a geophysics tutorial of a special kind. Brendon Hall explains how we can use machine learning to […]

The European Subsurface Hackathon – Hacking (before) the EAGE

We did it! We hi-jacked the weekend before the EAGE conference, called it the “subsurface hackathon” and the theme was games. It was the first time Matt Hall from Agile Geoscience tried it in Europe. He has some experience with these events already at the SEG, where gems like pickthis.io were created. But having a […]

Big Data in Oil and Gas – Fuzzy Classification

Data in oil and gas has always been large, but is it also big? Big data is more than Petabytes of seismic data or well logs. Big data is a buzzword in modern technology that isn’t clearly defined, yet used to sell expensive hard and software. What is big data all about? Big data is […]

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 […]

EBCDIC punch card from 1964.

How punch cards helped me get to know my data – EBCDIC

Today I learned something interesting. Old habits die hard and seismics is a pretty old business. There are a couple of standards for storing seismic data in file formats. One of them is the so-called SEG-Y standard. It starts with information about the data set called header and then the actual seismic data is written. […]
