Modeling and Inversion of Microseismic Sources

Understanding the flow and deformation that occurs in a reservoir during fluid injection for enhanced oil and gas recovery is critical for maximizing the efficiency of production from unconventional reservoirs. A one-way coupled model for flow and deformation simulation is used for microseismic nucleation and subsequent wavefield modeling of the elastic emissions from the microseismic events. Full waveform inversion accurately estimates the full spatial and temporal description of a microseismic source which includes not only the location and origin time of the source but also the elastic waveform itself. This is joint work with Jordan Kaderli, Matt McChesney, and George McMechan.
