#46: How science can protect infrastructure and homes

Olga Nedorub and Diana Sineva preview IMAGE 2022 and the upcoming panel, "Changing The Dynamics Of Energy Use." Olga starts with a brief overview of the technical program at IMAGE and how Diana reached out to her to host this panel. Next, Diana explains how energy efficiency is the glue to the current energy transition, the difference between energy conservation and energy efficiency, and why attendees should attend the panel. Diana also highlights why 40% of the current energy is wasted, why this estimate is low, and how to improve this number without sacrificing comfort or the bottom line. In Q3/Q4 2022, SEG will also host a short course on this topic. Details will be announced soon. Olga Nedorub is G&G Team Lead - Legacy Assets (Permian, Gulf Coast, Gulf of Mexico) at Apache Corporation and SEG 2020 Technical Program Chair. Diana Sineva is a small business and energy efficiency consultant with over 20 years of experience in the International O&G Exploration industry, focusing on emerging technologies, process optimization, and corporate sustainability.

Arnab Dhara discusses his paper, "Physics-guided deep autoencoder to overcome the need for a starting model in full-waveform inversion," in the June issue of The Leading Edge. In recent years, physics-driven machine learning applications have been proposed wherein physics is integrated into the data-driven model to improve the ability of the machine learning methods to generalize and potentially overcome gaps in the physical theories. Solving geophysical problems by using hybrid physics-based and data-driven solutions has the potential to address simplifications in the physical models as well as overcome shortcomings with training data sets. Ultimately, they may refine and improve our understanding of the physics underpinning data sets. In this conversation, Arnab proposes employing deep learning as a regularization in full-waveform inversion. He explains why physics-based solutions with machine learning are challenging to develop, how he made it possible to train the network without known answers, and why he tested his approach with the Marmousi and SEAM models. Arnab also shares why this research took over 20 years to build on the initial idea and how he used full-waveform inversion without a starting model. This is a cutting-edge conversation that may represent the future of FWI. RELATED LINKS * Arnab Dhara and Mrinal K.

Yanlong Niu discusses his paper, "In-situ physical properties of reclaimed lands in Singapore," from the May issue of The Leading Edge. Reclaimed land construction is crucial for the sustainable development of the land-scarce city-state of Singapore. To characterize the physical properties of two different types of reclaimed lands, Yanlong and his co-authors conducted both active and passive seismic surveys. Yanlong explores the value of multichannel analysis of surface waves to investigate these lands and shares what they discovered with these pioneering tests. These in-situ measurements are crucial for civil engineering constructions and the redevelopment of reclaimed lands in the future. So he also offers tips on how other geophysicists can build upon this study in their communities.

Ariel Lellouch discusses his upcoming Middle East and Africa Honorary Lecture, "Applications of fiber-optic sensing to borehole seismology." Distributed Acoustic Sensing (DAS) is an emerging technology that leverages optical fibers to record the seismic wavefield with an unprecedented spatial resolution. In this conversation with host Andrew Geary, Ariel makes a case for geophysicists to utilize DAS data in their work and why it's essential to look at data without any pre-made ideas. He also outlines the significant benefits of vertical DAS arrays and how to know when to use vertical or horizontal DAS. This is an excellent primer on DAS and a convincing case for why every geophysicist would benefit from engaging with this technology.

Mojtaba Rajabi discusses his upcoming Pacific South Honorary Lecture, "Present-Day Crustal Stress Across Spatial Scales." The present-day crustal in-situ stress field is of extreme importance for understanding both natural processes (e.g., understanding neotectonics, earthquake, and seismic hazard assessment) and anthropogenic activities (e.g., exploration and production of geothermal energy, groundwater, hydrocarbon, mineral resources, CO2, and hydrogen geo-storage). Analysis of the present-day stresses in numerous basins from across the world reveals that significant and complex variations in the present-day stress orientation are commonly observed at different scales. Mojtaba's lecture aims to investigate the pattern of crustal stress at different spatial scales to better evaluate the causes and consequences of contemporary stress in the earth’s crust. In this conversation with host Andrew Geary, Mojtaba shares why it's necessary to understand the present-day crustal in-situ stress field, the impact of investigating crustal stress at different scales, and the causes and consequences of contemporary stress in the earth’s crust. He also goes over the concept of stress mapping and what his years of experience studying basins have taught him.
