SVD enhanced seismic interferometry for traveltime estimates between microquakes
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
In general, Green’s functions obtained with seismic interferometry are only estimates of the true Green’s function, introducing uncertainties to the information recovered from them. However, there are still many cases in ...
Microquake seismic interferometry with SVD enhanced Green's function recovery
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
The conditions under which seismic interferometry (SI) leads to the exact Green’s function (GF) are rarely met in practice, resulting in errors in the recovered GF. To alleviate this problem, we employ additional information ...
Interferometric hydrofracture microseism localization using neighboring fracture
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011-05-19)
Hydraulic fracturing is the process of injecting high-pressure fluids into a reservoir to induce fractures and thus improve reservoir productivity. Microseismic event localization is used to locate created fractures. ...
Carbon sequestration monitoring with acoustic double-difference waveform inversion: A case study on SACROC walkaway VSP data
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
Geological carbon sequestration involves large-scale injection of carbon dioxide into underground geologic formations and is considered as a potential approach for mitigating global warming. Changes in reservoir properties ...
Visibility Analysis using Reverse Time Wave Sensitivity for Time-Lapse Target-Oriented Imaging
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
Identifying the relationship between surface seismic data and a particular region in the earth, referred to as visibility analysis, is important because it facilitates the optimization of the quality and speed of the imaging ...
