Characterization of a carbonate geothermal reservoir using rock physics-guided deep neural networks

The Leading Edge | Fabien Allo, Jean-philippe Coulon, Jean-Luc Formento, Romain Reboul (CGG) ; Laure Capar, Mathieu Darnet, Benoit Issautier, Stephane Marc, Alexandre Stopin (BRGM) ©2021 SEG

Deep neural networks are used to characterize the porosity and permeability of the Dogger formation north-east of Paris, France, that already hosts a number of geothermal plants and is set to become even more important with the transition toward renewable energies. Due to the ...

Multiwave Inversion: a key step for depth model building - examples from the Sultanate of Oman

The Leading Edge | Daniela Donno, Mohammad Farooqui, Mostafa Khalil, David Mccarthy, Didier Solyga, Jillian Courbin, Anthony Prescott, Laurie Delmas, and David Le Meur ©2021 SEG

The near surface in the Middle East is characterized by the presence of very shallow fast carbonates and anhydrites interleaved by slow-velocity clastic layers, resulting in sharp velocity inversions. We present here examples from two case studies in the Sultanate of Oman using Multi-Wave ...

Geothermal Energy: A new frontier for energy – and petroleum geoscientists

Geo Expro | Ellie Macinnes ©2021 GeoPublishing Ltd

While the subsurface geoscience skills required for geothermal exploration and development differ from those required for oil and gas, there are existing skills and technologies that are highly transferable. Moreover, as the shift for geothermal resources moves away from high-enthalpy areas and towards sedimentary ...

Full-waveform inversion for full-wavefield imaging: Decades in the making

The Leading Edge Journal | Rongxin Huang, Zhigang Zhang, Zedong Wu, Zhiyuan Wei, Jiawei Mei, and Ping Wang © 2021 SEG

Seismic imaging using full-wavefield data that includes primary reflections, transmitted waves, and their multiples, has been the holy grail for generations of geophysicists. To be able to use the full-wavefield data effectively requires a forward modeling process to generate full-wavefield data, an inversion scheme ...
