Time-Lapse Monitoring of Earths Interior Posters

Submit an Abstract to this Session



Session ID#: 26600

Session Description:
Earthquake mechanisms and the effects of hydraulic fracturing are major subjects of research in global- and exploration-scale geophysics, respectively. The analysis of repeated measurements of seismic, gravitational, and electromagnetic wavefields probing Earth’s dynamic interior leads to better subsurface models. This session is focused on studies concerning the monitoring of earthquake zones, oil and gas fields, reservoirs, and engineering structures. In particular, we are interested in works on stress-induced anisotropic effects on elastic and electromagnetic properties. Theoretical developments in the analysis of wave phenomena and computational approaches that enhance resolution, quantify uncertainty, and better constrain the dynamically evolving properties of the subsurface in pre-stressed areas, such as fault zones or fractured reservoirs, and related case studies are welcome. Finally, we invite presentations on microseismic and nonlinear methods, and studies in rock-physics with a focus on multiparameter evolution.
