PESA NSW March Technical Meeting (cancelled)

Tuesday, 31 March @ 12:00 pm - 2:00 pm (Australia/Perth time)

$15 – $75

Guest Speaker: Sergey Fomel

Sergey Fomel is Wallace E. Pratt Professor of Geophysics at The University of Texas at Austin and the director of the Texas Consortium for Computational Seismology (TCCS). At UT Austin, he is affiliated with the Bureau of Economic Geology, the Department of Geological Sciences, and the Oden Institute for Computational Engineering and Sciences. Sergey received a PhD in geophysics from Stanford University in 2001. For his contributions to exploration geophysics, he has been recognized with a number of professional awards, including SEG’s J. Clarence Karcher Award in 2001 and the EAGE Conrad Schlumberger Award in 2011. He has served SEG in different roles, most recently as the Vice President, Publications. Sergey also serves as the project manager for “Madagascar,” an open-source software project for geophysical data analysis.

Dear members,

Due to COVID-19 concerns this event will be cancelled.

However, SEG DL Sergey Fomel will present live, virtual lectures. Details will be available soon at https://seg.org/Education/Lectures/Distinguished-Lectures/2020-DL-Fomel.

PESA and ASEG apologise for any inconvenience.

PESA NSW invites you to a technical lunch on Tuesday 31st March Co-hosted with ASEG

Automating seismic data analysis and interpretation

Recent developments in artificial intelligence and machine learning can automate different tasks in data analysis. I will discuss the quest for automation by tracking the development of automatic picking algorithms, from velocity picking in seismic processing to horizon picking in seismic interpretation. We will search for the limits of automation to discover the distinguishing qualities that separate human geophysicists from machines.

The automatic picking algorithm follows the analogy between picking trajectories in images with variable intensities and tracking seismic rays in the subsurface with variable velocities. Picking trajectories from local similarity panels generated from time shifts provides an effective means for measuring local shifts between images, with practical applications in time-lapse and multicomponent image registration, matching seismic with well logs, and data compression using the seislet transform. In seismic interpretation, automatic picking finds additional application for tracking fault surfaces, salt boundaries, and other geologic features.

The power of automatic picking is further enhanced by novel deep learning algorithms. The deep learning approach can use a convolutional neural network trained on synthetically generated images to detect geologic features in real images with an unmatched level of performance in both efficiency and accuracy. The lessons to learn from these developments include not only the potential for automation, harvested through artificial neural networks and modern computing resources, but also the potential for human ingenuity, harvested through professional networks.
