Announcement from CSH-SEG: The symposium will be held over two days and will consist of a keynote address, multiple speakers each day, and two exciting lunchtime events. The first will be our traditional SEG Student Challenge Bowl competition. This will be held online and will feature the traditional battle between student geophysicists to be crowned the winner of the GSH Challenge Bowl and to earn a place at the Challenge Bowl finals at the SEG Annual Meeting in the fall! The second event will be the announcement of the winners of the Machine Learning Competition being run by the Data Science & Machine Learning SIG and will include an overview of the competition challenge, the announcement of the winner, and a presentation by the winning entry.
Keynote Speaker: Jake Umbriaco, Digital Platform and Services Manager, Subsurface – Chevron Confirmed speakers and topics include: Aria Abubaker, Schlumberger Machine Learning for Geoscience Applications Satinder Chopra, SamiGeo Some Machine Learning Applications for Seismic Facies Classification Hugo Garcia, Geoteric Automated Fault Detection from 3D Seismic using Artificial Intelligence Elive Menyoli, Emerson Wavefield Separation via Principle Component Analysis and Deep learning in the Local Angle Domain Tom Smith, Geophysical Insights The Scientific Universe from Square One to SOM Yuting Duan, Shell Estimation of Time-lapse Timeshifts using Machine Learning Jon Downton, CGG Predicting Reservoir Properties from Seismic and Well Data using Deep Neural Networks Wenyi Hu, AGT & UH Progressive Transfer Learning for Low Frequency Prediction in FWI
We are pleased to have our next technical luncheon on Thursday, April 8th at noon. This virtual luncheon will be held through Zoom.
This month is a special session featuring three speakers from the graduate geology program at Cal State Bakersfield. Typically, our society hosts an annual poster session with CSUB’s geology students. With the Covid-19 restrictions still in place, the society has decided to invite a handful of Master’s candidates to present brief virtual talks on their current research. The speakers and titles of their talks are listed below.
Additionally, the society will be awarding our annual field camp scholarship to this year’s CSUB Outstanding Geology Student.
Kari Hochstatter – “X-ray Diffraction Mineralogic Analyses on Core Samples of the San Joaquin Basin, California: A Pilot Study for Kaolinite to Dickite Diagenesis”
Please join us for the PCS-SEG monthly luncheon on Wednesday, March 10th. This will be a virtual meeting held using the Zoom meeting platform.
The meeting will feature Christof Stork of Land Seismic Noise Specialists. The title of his talk is “Addressing land seismic data quality issues that cannot be easily fixed by huge fold”.
Abstract Interpreters can be frustrated by that land seismic data is often 10-100x noisier than marine data. There is room for optimism since source and receiver counts for land seismic data are each recently going up by about 10x. This increases total fold by about 100x, which is a revolution. But, there are still some significant noise issues the huge fold does not fix well: 1) consistent wavelet distortion of the near surface, 2) near surface scattering, 3) guided waves, 4) 3C noise, and 5) acquisition access issues. Because of the competitive & heuristic nature of land seismic acquisition and processing, these topics have been R&D starved. I will demonstrate the issues and show there is potential for significant technology improvements that are complementary with the new high fold data.
Christof Stork graduated with a Ph.D. in geophysics from Caltech in 1988 and then a Postdoc at Stanford. He has been involved with 5 startup companies, of which 4 1/2 were successful. Christof has been a leader in reflection tomography, wave equation migration, FWI, and land acquisition considerations. Christof has twice had a measurable impact of greater than $1 billion on the industry with Wave Equation migration and RTM.

Please join us for the PCS-SEG monthly luncheon on Thursday, February 4th. This will be a virtual meeting held using the Zoom meeting platform.
The meeting will feature Dan Hollis, Chief Executive Officer of Sisprobe SAS. The title of his talk is “Use of Ambient Noise Surface Wave Tomography for Petroleum Exploration in the Lowlands of West Papua, Indonesia”.
Please join us for the PCS-SEG monthly luncheon on Thursday, January 14th. This will be a virtual meeting held using the Zoom meeting platform.
The meeting will feature Andres Chavarria, Oilfield Services Technical Director at OptaSense. The title of his talk is “Geophysical Distributed Sensing within Instrumented Assets”.
Abstract Reservoir monitoring with distributed acoustic sensing has proven an effective cost saving tool for various assets in a wide range of basins. Using fiber optic that often times is deployed for production monitoring purposes provides geoscientists with low cost tools to conduct measurements like seismic, microseismic and strain.
Here we show recent examples of DAS seismic projects where fiber for monitoring different assets was used to monitor reservoir changes. We focus on time lapse applications including steam and water injection, CO2 storage as well as passive microseismic and earthquake monitoring.
Bio Andres Chavarria is OptaSense’s Oilfield Services Technical Director. His current focus is the use of distributed sensing fiber optic data for engineering and geoscience applications.
He has a background on borehole seismology (MS and VSP) and was previously the Geophysical Processing Manager at OptaSense, SR2020 and Paulsson. He has conducted work in other areas of geophysics including geothermal, mining and groundwater. He holds an Engineering Degree on Geophysics from the National University of Mexico and a PhD Degree on Geophysics from Duke University.
