Time-lapse studies of seismic data are often to detect subtle seismic waveform differences between baseline and monitor surveys (Lumley, 2001). These differences are typically caused by the changes in localized areas, such as gas or fluid volumes in conventional reservoirs, or stimulated reservoir volumes (SRV) in unconventional hydraulic fracturing. To identify these changes in the elastic properties, full-waveform inversion (FWI) is obvious an interest of the studies because of its capability to produce a high resolution velocity model (Bian et al., 2017; Kotsi and Malclm, 2017; Maharramov et al., 2016; Peng et al., 2018; Tarantola, 1984; Watanabe et al., 2004; Zhang and Huang, 2013). There are five FWI schemes in time-lapse studies: a) parallel, b) sequential, c) central-difference, d) double-difference, and e) joint inversion workflows. These methods are illustrated in Figure 1.
Speaker Biography: Weizhong Wang, GeoTomo
Weizhong Wang received his Ph.D. in Automation from Tsinghua University, China in 1989. After graduation, he joined the Geophysical Lab at the University of Toronto as a postdoctoral fellow, working on Canada’s national research project LITHOPROBE. In 1993, he was employed at Veritas Seismic in Calgary as a research geophysicist, then GeoCenter, and PGS before joining GeoTomo in 2005. He currently is the vice president of GeoTomo, leading the efforts in technology development at GeoTomo LLC.
