190: The unique power of combining GPR and FWI
15/06/2023 Duración: 22minAnja Klotzsche discusses her Near-Surface Global Lecture, "Unlocking the potential of GPR for subsurface characterization by using full-waveform inversion." The heterogeneous near-surface consists of the complex interactions between rock, soil, water, air, and living organisms, which determine the availability of life-sustaining resources such as water. This environment has been increasingly exploited for human needs, such as water supply, to store our waste and food production. To assess the environmental risk associated with such exploitation and exploration, the near-surface must be investigated and characterized with high-resolution methods to enhance our understanding of hydrological and biogeochemical processes. In this conversation with host Andrew Geary, Anja describes the recent developments in FWI that have impacted how to apply GPR. She outlines a few of her favorite GPR applications, the impact of AI on GPR, and the role GPR and FWI can have in improving management decisions. Anja also shares t

184: Water is Life - GWB Ghana Water Project
20/04/2023 Duración: 27minDr. Elikplim Abla Dzikunoo and Abdul Rashid Seidu discuss their Geoscientists without Borders project, "Provision of potable water to communities in northeastern Ghana." This GWB project will directly help the inhabitants of two communities (Zagsliari and Salinwia) located within the Nasia river basin in the West Mamprusi district – Northeastern region of Ghana. In Zagsliari, men, women, and children will all benefit from potable water. Children will especially benefit as the current water supplies in the community expose them to diseases like cholera and dysentery. In Salinwia, families will profit greatly from the provision of boreholes, enabling them to engage in year-round irrigation farming to improve their economic fortunes and sustenance for themselves and their livestock. This was done by using Electrical Resistivity Tomography techniques to define and interpret geo-electric sections and models to show the subsurface lithology distribution and provide scientific data that will inform groundwater man

175: Searching for the perfect digital twin of the seismic reservoir
19/01/2023 Duración: 14minThe 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.

174: From the beach to the reservoir - the power of microseismicity
12/01/2023 Duración: 15minLeo 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
