Geysers in Slow Motion

Geysirs are a force of nature. Even as a kid I knew about Old Faithful and mind you it’s across the Atlantic for me. A natural system that produces a clock like massive effect just seems magical. Luckily, the YouTube channel “Slow Mo Guys” went to Iceland and filmed a Geysir. The name may give […]

Keynote Bonanza and No Coffee – The EAGE / PESGB ML Workshop

Last month EAGE and PESGB organized the first machine learning workshop in geoscience in Europe. Clearly, I had every intention of going. And obviously, I met many of my favourite co-conspirators there, when I did. The workshop was divided between a day of keynotes and a day of technical talks. The keynotes accompanied the PETEX […]

The Good, The Bad, The Weird – 2018 SEG Meeting

The SEG Annual Meeting 2018 in Anaheim, California has concluded. This was my first SEG and I can only compare it to the EAGE Exhibition and Conference I attended. There was light. There was shade. There were oddities. The Light Let’s talk about the light. You may have noticed that I am fully riding the […]

Cheaper Deep Learning by Transfer Learning Cats to Seismic [SEG Conference 2018]

This years SEG I got the opportunity to present some of my work on transfer learning. In automatic seismic interpretation, progress is preceived as incremental already, although the field has only been established fairly recently. It was shown with new deep neural networks, usually convolutional neural networks, that reproducing human seismic interpretation is possible. This […]

Preprints – What’s the worst that could happen?

Early career scientists are laying the building blocks of their career. Giving away your best ideas for free and everyone to read can seem risky. Pre-prints, on the surface, may look just like that, but are they? Pre-print servers like EarthArXiv are sprouting in many scientific disciplines. They proclaim the benefits of research being cited […]

I placed 1300th on Kaggle and it’s amazing!

I placed 1360 in a deep learning competition and here’s why that is a win in my book. I spend too much time on social media, but this time I was lucky. I checked my feed on LinkedIn quickly and saw an announcement from TGS a seismic contractor. They had teamed up with Kaggle, a […]

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. […]

Data Is Not Neutral

  I like data driven processes. You’ve seen me drum on about CRS and Full-Waveform Inversion. Sometimes we like to pretend that data is pure. Well , it’s noisy and full of kinks but if we process it just right, we extract the truth. Turns out that is a little bit wrong. The data collection […]

Steal my CV!

Recently, I have updated my CV. Problem is, when I see the MS Word templates for resumes and CVs, I repulse. Few things scream 80s as much as these do. Now, let me get one thing out of the way, I have had feedback that some recruiters may prefer the 80s style. They’re used to […]

Geophysical Assumptions

If you assume you make an ASS of yoU and ME. That may be true in personal connections, but assumptions are necessary in physics. Particularly, geophysics needs all the assumptions it can get. The subsurface isn’t exactly nice, giving us data. We can only look from one side (mostly). The Earth itself filters our signal, […]
