SEG Seismic Working Workshop - Reproducible Tutorials - August 9-13, 2017

Working Workshops as opposed to "talking workshops" are meetings where the participants work in pairs or small teams to develop new software code or to conduct computational experiments addressing a particular problem. In this workshop participants will work in small groups to create short, reproducible, geophysical tutorials. These tutorials are inspired by The Leading Edge geophysical tutorial articles. Groups will make lightning talks (a five minute presentation) at then end of the workshop. An open repository will be created to share presentations and code after the workshop.


Groups of two or three participant were formed at the working workshop to create reproducible tutorials. The tutorial should be on a topic of interest to seismic interpreters, applied geophysicists, and general earth scientists. It should be about 1500 words, two or three figures, and code to makes the figures. Groups used any system to create and share the code that allows the tutorial figures to be reproduced by readers after the workshop. The tutorials may be candidates for publication (eg The Leading Edge geophysical tutorial articles or the software section of Geophysics). groups came up with their own ideas or read previous TLE tutorials, Geophysical Image Estimation by Example (http://sepwww.stanford.edu/sep/prof/), Seismic Unix demos, Madagascar reproducible documents, or Geophysical Society of Houston “Tutorial Nuggets”. Study, extend, or translate some of this material to another system. Collaborate and share your experience in a lightning talk (a five minute presentation).

Participants used their own laptops and software to create a tutorial during the workshop. Wifi internet access was available.

This working workshop provided a forum for geophysicist to learn, contribute, and network.

Synopsis of results with links

Overview Presentation of Results

Karl Schleicher completed a report of the highlights of the working workshop. view Schleicher's overview presentation

Keynote Presentation by Matt Hall

Matt Hall made a presentation via Skype at the beginning of the workshop describing his experience in participatory meetings. He has organized several Geophysics Hackathons. He provided an overview of the Tutorials in The Leading Edge. view Hall's Keynote presentation.

Luke Decker, Matt Sexton, Will Sanger

This group created tutorial material on Kirchhoff migration. Started with an SEP tutorial from the Madagascar source code repository they implemented least squares migration in Madagascar and Kirchhoff migration and modeling in a Jupyter notebook. A seperate accomplishment was to identify a web site that describes how to install Madagascar using Docker. view Sanger's presentation

Pongthep Thongsang, Lian Jiang, Hoa Li

This group created a Madagascar modeling and processing tutorial. Starting with a modeling and processing papers in the Madagascar source code repository they created a beginners tutorial for the Madagascar software package. Their tutorial demonstrates finite difference modeling of cary of there Marmots 2 model and simple processing including NMO, stack, and post stack depth migration. The paper will soon be added to the Madagascar repository and the online reproducible papers. view paper by Thongsang et al

Wenyuan Zhang

Wenyuan Zhang encounterred problems running parallel Madagascar programs on the University of Houston Cluster. These are due to onitereaction between Madagascar patella options, the cluster configuration, the slum queueing system, and the scons environment. He was able to make small updates to Madagascar source code files api.c and config.py and his scripts now run. These updates have been included in the Madagascar distribution repository.

Karl Schleicher

Reproduces one to "The Leading Edge Tutorials", Linear Inversion. The Jupyter notebook must be changed if you want to run using Python 2.7 instead of 3.5. This work lead to a new tutorial for :The Leading Edge" on the Conjugate Gradient Method. This tutorial is tentatively scheduled to be published in April 2018. view schleicher's tle tutorial
