2016 Working Workshop Attendees

Overview

Working Workshops as opposed to "talking workshops" are meetings where the participants work together (possibly divided into pairs or small teams) to develop new software code or to conduct computational experiments addressing a particular problem.

This workshop invited participants to extent the results of the 2015 SEG 3D Seismic Processing Working Workshop. The workshop 2016 report is here. Processing templates created in that workshop were incorporated in the reproducible processing flows and new programs in Madagascar. The objective of the 2016 working workshop were:

  • Use the scripts to develop seismic processing skills.
  • Reproduce and improve these results in other proprietry or open software
  • Extend Madagascar, Seismic Unix, or other open software packages.

The workshop was held August 17-20, 2016 at the Bureau of Economic Geology's Houston Research Center. It was attended by 21 participants from 9 organizations. The participants were students, post doctoral fellows, academic staff, and industry professionals. The meeting was sponsored by Rice University (TRIP), University of Texas at Austin (TCCS), and SEG.

Participants made final "lightning talk" presentations describing the programs, parameters, and data (input and output) in sufficient detail so the results can be reproduced after the workshop. The presentations, description of programs and parameters used, input data, and output data are archived and available for training and research.

Many participants started with existing reproducible Madagascar scripts from this link. Participants brought laptops with the software to use to process the seismic data during the workshop. We learned by comparing results from various software systems and archiving a set of processing templates. It was an opportunity for academics to pick up some of the "art" of seismic processing from seasoned industry processing staff. It was also an opportunity for industry to illustrate interesting problems in land processing and "set up" example scripts for university researchers to validate their theory.

Synopsis of lightning talks with links

John Gilstrap

John is a geophysical industry linux system administrator. He created a virtual Linux system with Madagascar and Seismic Unix for first time users of these open software packages. He ran most of a simple processing sequence on the Teapot Dome survey.processing sequence.

Mendez, Vergas, and Shukula

These undergraduate student and early career geophysicist configured their computers, installed Madagascar, and reproduced the basic processing sequence on the Teapot Dome 3D survey.

Dafni and Symes

Rice University post doctoral fellow and professor created a processing the teapot dome 3D survey with Seismic Unix. They observed traces with offset less than 2000 feet contained most of the worst bad amplitudes. They would like to continue work using surface consistent decon and scaling. They would ike to understand why sustatic applies a large constant shifts. They challenge others to recreate their processing using the sftah programs in Madagascar.

Xia, Gong, Kim, and Son

Early career geophysicists (PhD) and graduate students tried to image beneath a low velocity zone using far offsets. They wrote new code to rotate the processing grid. There was not time at the workshop to apply prestack depth migration, but they recommend continuing their strategy using depth migration.

Dmitrii Merzlikin

Dmitrii is a graduate student. He used the teapot dome to validate his new diffraction imaging program. He plans to continue developing his algorithm in Madagascar and test using the Teapot Dome dataset.

Chuck Andrews

Chuck is a senior industry geophysicist. His goal at the workshop was to provide processing oversight and learn Seismic Unix. He showed results of his hires decon (a competitor to Castagna and Geotrace) applied to the Teapot Dome 3D survey.

Post Working Workshop Evaluation

Six out of eight surveyed after the event said they would attend another working workshop. Seven out of eight would recommend the workshop to a friend. When asked to recommend a dataset, three recommended processing Teapot Dome again and three recommend processing a land 2D dataset. The survey said the best part of the workshop was collaborating with people from different universities and backgrounds.
