3-D seismic interpretation with deep learning: a set of Python tutorials

alt text

Here we are sharing our code, tutorials and examples used to interpret geological structures (e.g. faults, salt bodies and horizones) in 2-D and/or 3-D seismic reflection data using deep learning. The repository is organised in a series of tutorials (Jupyter notebooks) with increasing degree of difficulty. We show step-by-step how to: (1) load seismic data, (2) train a model and (3) apply the model to map different geological structures. You can find a few visual examples on our poster and more technical details in our preprint.

To get started, you don't need any special hardware, software, data or experience - just a bit of time. Check out tutorial-1/tutorial-1.ipyng.

Tutorials

Salt

  • This tutorial shows you how to map salt in a 2-D seismic image using a 2-D convolutional neural network for pixel-wise classification.
  • This tutorial describes how to speed up our mapping using U-Net type convolutional neural networks.

Faults

  • This tutorial shows you how to map tectonic faults in a 3-D seismic volume.
  • This tutorial will explain how to translate our fault mapping workflow to 3-D.
  • This tutorial will hows you how to quantify uncertainty during fault mapping (not ready yet)

Horizons

  • This tutorial introduces you to mapping horizons in a 3-D seismic volume.
  • This tutorial shows you how to improve horizon mapping using a 2-D CNN
  • This tutorial will explain how to translate our horizon mapping workflow to 3-D.

Acoustic impedance

  • This tutorial will show how to invert synthetic seismic data for rock properties (not ready yet)
