	==SEG Working Workshop - Python and Julia for Geophysics - August 8-11, 2018==		==SEG Working Workshop - Python and Julia for Geophysics - August 8-11, 2018==

			In late August, 16 participants from 12 organizations collaborated at the University of Houston to learn how program geophysical applications using Python and Julia. These languages are good for prototyping and applying selected geophysical algorithms. Our goal was to promote more widespread use of these languages.

			[[Working Workshops]] as opposed to "talking workshops" are meetings where the participants work in small teams to develop new software code or to conduct computational experiments addressing a particular problem.

	~~[[Working Workshops]] as opposed to "talking~~ workshops~~" are meetings~~ where ~~the participants work in~~ small ~~teams~~ to develop ~~new~~ software ~~code~~ or to conduct computational experiments addressing a particular problem. This ~~workshop asks~~ participants ~~to create small groups to identify~~ and ~~address obstacles to~~ more ~~widespread use of Python and Julia in the geophysical community~~. ~~Results will be shared in lighting talks and code repositories~~.		This is the sixth year that TCCS has organized working workshops where small groups collaborate to develop software or conduct computational experiments addressing a particular problem. This year participants were students, academic staff, and industry professionals. Projects included machine learning, 3D plotting, parallel processing, wave equation modeling, and well log analysis. For more information visit http://www.ahay.org/wiki/HoustonWW2018.

	~~This is the sixth year we have organized a working workshop. Information about previous events is at this [[http://www.ahay.org/wiki/Working_Workshops website]].~~

			===Rafael Pinto and Thu Nguyen===
			Rafael and Thu processed wells from the Poseidon project in the NW Shelf Australia. They used lasio to read the data into a Panda data frame, then loaded the data into an sql database. Lasio processes logs from a single well. The sql database is good to manipulate multiple wells on a project. They visualized cross plots in matplotlib and datashader. Datashader plots were better. Their jupyter notebook can be downloaded from this link [https://drive.google.com/open?id=16Ul7r32VZRbrs7JxMIuv0ip0a0AG3JoV].<br>

	Participants ~~brough~~ their ~~own~~ laptops and formed small groups. ~~These groups~~ picked projects and started to make examples of geophysical applications written in Python and Julia. About once a day we all checked in to talk about progress. Sometimes participants collaborated with different groups. After two and a half days we shared results in a lightning talks (five minute presentations). ~~I think everyone~~ left the workshop with some new skills, ideas, and acquaintances.

			Derek and Mark created Jupyter notebooks with Python to read the Teapot Dome 3D segy final volume and displayed using Matplotlib and Mayavi. They also read horizon data which they used to flatten horizons and display stratal slices. They created the amplitude envelope and spectral decomposition volumes and displays.
