Seismic Soundoff

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 reservoir models and the historical connection between seismic data sets and reservoir modeling. She also explains the power and future of ensemble modeling and spotlights an alternative to the arduous training libraries for machine learning and seismic. Katie Baker is the Longui Subsurface Lead - Angola Blk0 at Chevron and President-Elect at the Geophysical Society of Houston. Listen to the full archive at https://seg.org/podcast.

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 inspired this talk and what it means to measure data the right way. And Leo explains why improving the understanding of induced seismicity is important. This conversation will showcase the value of asking the right questions and how to maximize the value of microseismicity for geophysical workflows.

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 years. Paul also shares why every geoscientist needs to be aware of this crisis, how it impacts their work, and what actions to take to address the issue. This is an inspiring, humbling, and necessary conversation. Listen to the full archive at https://seg.org/podcast.

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. Large-scale environmental problems usually involve a mixture of science (geology, hydrology, geophysics, ecology, etc.), applied science (engineering, natural resource management), and human dimensions (politics, economics, culture, etc.). Governments often struggle with these problems, and researchers usually deal with a single aspect, two or three at most. Kirsten and Klaus lead a GWB project to solve the water problems of two communities in Nepal - Phortse and Lobuche. These communities sought help to determine the placement and capacity of a water filtration and storage facility that would provide potable water to the community members year-round. The placement of the system is essential so that it is resistant to the impacts of climate change and earthquakes. In this episode, you will hear exclusively from Kirsten and Klaus as they take you on a journey from discovering the need for this project to what they hope they will contribute to these communities. Along the way, they highlight the meaningful contributions of students from the U.S. and Nepal, how the local communities have taken leadership in this project, and share the most enriching experiences for them. This is a powerful example of the significant contribution geoscientists can make when focused on a meaningful project for a local community. Listen to the full archive at https://seg.org/podcast.
