A unified framework for relative source localization using correlograms
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
We study the problem of determining an unknown event location relative to previously located events using a single monitoring array in a monitoring well. We show that using the available information about the previously ...
Analysis of location uncertainty for a microearthquake cluster: A case study
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
In many reservoirs, an increase in permeability and conductivity is achieved by hydraulic fracturing/stimulations which open cracks and fractures that then act as pathways for fluids to navigate in the subsurface. Mapping, ...
Detecting medium changes from coda by interferometry
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
In many applications, sequestering CO[subscript 2] underground for example,
determining whether or not the medium has changed is
of primary importance, with secondary goals of locating and
quantifying that change. We ...
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. ...
