Seismic Soundoff

Roman Pevzner discusses his Honorary Lecture, "Surface and borehole seismic monitoring of CO2 geological storage." Geological carbon capture and storage (CCS) or sequestration is a critical component of CO2 emission reduction, which aims to alleviate global climate change. Geological carbon storage always requires a subsurface monitoring program, and seismic methods play an important role. In this conversation with host Andrew Geary, Roman explains why a subsurface monitoring program is necessary for geological carbon storage and the range of seismic methods used to monitor CO2 storage. He discusses how the Australian CCS projects featured in the lecture highlight the evolution of the seismic monitoring technology used for sequestration. He also explores the advantages and disadvantages of permanently mounted seismic sources and characterizes passive data analysis. This conversation explores the goal of this lecture, the perfect audience for this talk, and the one question Roman hopes attendees take with

The seismic data set is a fundamental requirement for producing oil and gas fields. Reservoir modeling utilizing seismic interpretations drove insights into reservoir quality and performance, helping to understand the communication between reservoir units and wells, particularly in fields with many wells. Over time, technological advancements led to a reduction in the cost of reservoir modeling, while increased acquisition, processing, and utility of seismic data provided the means to drive innovation toward incorporating seismic. Today, 3D and 4D seismic data play pivotal roles in defining and updating reservoir models where hundreds to thousands of simulations can be realized in a reservoir model to explore history matching and model uncertainties. In this conversation with host Andrew Geary, guest editor Katie Baker explores seismic reservoir modeling as highlighted by five papers in The Leading Edge. Katie showcases the key technological advancements that unlocked seismic in defining and updating reservo

Leo Eisner discusses his Honorary Lecture, "Mapping pore pressure with beach balls." The stress field of the Earth's crust has been studied for many decades as a part of seismology and geomechanics. Traditional stress inversion methods utilize focal mechanisms of earthquakes as this is typically the only data available at a regional scale and lower crust. With earthquake mechanisms, it's possible to reconstruct principal stress directions and a ratio of principal stress magnitudes but not the full stress tensor. However, combining data from reservoir injections and focal mechanisms from induced microseismicity overcomes this limitation. In this talk, Leo will show how they applied joint stress inversion to a geothermal and unconventional dataset and illustrate how microseismicity can be used to map pore pressure. In this conversation with host Andrew Geary, Leo breaks down the perfect audience for this lecture and the insights attendees will take away. Leo highlights how the bad attitude of a manager inspir

Paul Bauman discusses the inaugural Global Sustainability Lecture series, "A Strategy for Improving Rural Water Supply Development in Sub-Saharan Africa." Though 98% of the available freshwater in the world is groundwater, groundwater resources are not easily available in much of the world, where subsurface water is the only option. Today, more than 400 million people in sub-Saharan Africa live in water insecurity, meaning they lack reasonable access to either sufficient quantities of water or water of acceptable quality. For rural populations, a direct consequence of water insecurity is food insecurity. In the Horn of Africa alone, more than 60% of the population is food insecure, with more than 20 million people approaching famine conditions. In this conversation with host Andrew Geary, Paul highlights how water impacts all 17 of the United Nations Sustainable Development Goals. He outlines the impact of two billion people living with water stress and how it could reach over five billion in the next ten y

Professors Kirsten Nicholson and Klaus Neumann lead a Geoscientists without Borders (GWB) project to find safe drinking water for two communities in the Sagarmatha National Park, Nepal. This country most famously is home to the world's favorite trekking destination - the Himalayans. Even though this area is popular with tourists, it struggles with adequate drinking water. Diseases due to unsafe water are some of the most common causes of death, with diarrheal disease accounting for 4.2% of the global burden of diseases. The situation is far worse in less economically developed, semi-arid mountainous regions where communities experience poor health due to contaminated drinking water. At the same time, these high-altitude regions face increasing pressure caused by climate variability, impacting precipitation patterns, seasonal snowpack, and glacial growth. The issues surrounding long-term resource management and the reduction of water-related vulnerability are complex and rarely involve simple solutions. Larg

Tim Johnson discusses his article in August's The Leading Edge about real-time electrical resistivity tomography (ERT). Time-lapse electrical imaging has been used for diverse scientific and engineering problems to monitor changes in the subsurface associated with fluid injections, fluid flow, solute transport, phase changes, and other physical and chemical processes. The burgeoning applications of time-lapse electrical imaging underscore its potential to provide valuable, qualitative insight to support the development of conceptual models of subsurface frameworks and processes. Tim and his co-authors posit that the next step in the evolution of time-lapse electrical imaging is autonomous, real-time monitoring, which has the potential to support real-time management decisions and feedback control of subsurface systems. Tim presents a framework for autonomous, real-time electrical imaging. He also shares two case studies of the framework in action and potential areas of development for this work. This forwar

Roel Snieder discusses his 2022 SEG-AAPG Distinguished Lecture, "Measuring variations in the seismic velocity as a diagnostic of rock damage and healing." Interferometric methods in seismology have made it possible to detect time-lapse changes in seismic velocity with an accuracy of about 0.1%. Combined with using noise as a seismic source, it is under the right conditions possible to detect such velocity changes on a near-continuous basis. In this conversation with host Andrew Geary, Roel shows surprisingly that the seismic velocity is not constant at all. It varies with the seasons, temperature, precipitation, and ground shaking. He also discusses how logarithmic healing in rocks is a widespread behavior that is akin in its generality to the Gutenberg-Richter law. Roel also provides insights into the role of spirituality in science and offers actionable tips on preventing burnout. This is a wide-ranging conversation with surprising insights into rocks, as well as how to live a successful life. RELATED L
