報告簡介：
This talk will present a development of CO2 sequestration. I’ll start to review the condition of CO2 sequestration. I’ll talk about the status of seismic time-lapse seismic monitoring. Then I will show the research progress my group made of advancing time-lapse waveform data processing algorithms to quantify the CO2 plume from a single indicator to full 3D image. To achieve full 3D geological image, I will show a newly developed time-lapse full waveform inversion for estimating seismic velocity and attenuation, and their uncertainty. The accuracy of the inverted model is increasing over time by assimilating more time-lapse data while the standard deviation is decreasing over lapsed time. Finally, I will discuss possible future topics of real-time seismic monitoring for continuously imaging the distribution of subsurface gas and fluids in the future large-scale CO2 sequestration experiments and reservoir management.
報告人簡介：
Tieyuan Zhu is an Associate Professor in the Department of Geosciences at Penn State. Dr. Zhu received his PhD degree from Stanford University in 2014, and MS degree from Chinese Academy Sciences Institute of Geology and Geophysics, and BS degree from China University of Geosciences. He received Best Student Paper from SEG 2013, and J. Clarence Karcher Award from SEG 2018 for his contribution in advancing seismic attenuation theory and practice in seismic exploration.
Dr. Zhu’s research interests include to use seismic waves to study energy and environmental problems (e.g. CO2 sequestration, geohazards, and critical zone science). His recent studies were deriving a new seismic wave equation in attenuating media and using seismic attenuation to improve seismic imaging. His recent projects are about real-time seismic monitoring of geological stored CO2 plume, and develop the understanding of fiber optics seismology for sensing earth and environment dynamics.
