Title: Seismic resolution, progresses and challenges
Speaker: Dr. Zhou Yu
Geophysicist and Data Scientist, BP Upstream Technology, Houston, TX.
Bio: Zhou received a B.S. in marine geophysics from Ocean University of China in 1983, a M.S. in geophysics from MIT in 1996, and a Ph.D. in geophysics from The University of Texas at Dallas in 2001. Zhou has pioneered several wavelet-transformed seismic data processing and non-intrusive corrosion detection techniques over his 30+ year career in both industry and academia. He has worked in BP’s Advanced Seismic Imaging group of the Upstream Technology for the past 20+ years. Zhou’s interests lie in innovative solutions to various signal processing and analysis problems. These include Kirchhoff migration operator anti-aliasing, 3D/2D land/VSP/DAS/OBN/ISS data denoise processing, 3D multiple attenuation, 3D/4D/5D conditioning data for AVO analysis, 3D inverse-Q process, 3D high-resolution (inverse-Q) seismic processing and 4D seismic processing.
Abstract: Seismic is the dominant geophysical technique for searching for and assessing, developing and producing hydrocarbon resources. It is also true for unconventional reservoir, geothermal energy and CCUS (carbon capture utilization and storage), where detailed high-quality subsurface image is required. Seismic resolution is a product of acquisition, processing and analysis. We can make significant steps forward by considering them as a whole. While seismic data processing advances have been very successful, it is still too common that we are not acquiring the data that we really need. Therefore, besides the processing technology advances, a key part of my presentation will be to advocate for continued investigation into how to acquire seismic data more safely, more efficiently and with dramatically improved sampling.
