Converted Phase Elastic Migration Velocity Analysis
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
Multi-component elastic seismic data collected at large offsets have the potential to be used in seismic imaging and velocity analysis. In this study, we present an approach for converted-phase elastic-transmission migration ...
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, ...
Joint microseismic event location with uncertain velocity
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
We study the problem of the joint location of seismic events using an array of receivers. We show that locating multiple seismic events simultaneously is advantageous compared to the more traditional approaches of locating ...
A unified Bayesian framework for relative microseismic location
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
We study the problem of determining an unknown microseismic 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 ...
Full-waveform Based Microseismic Event Detection and Signal Enhancement: The Subspace Approach
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
Microseismic monitoring has proven to be an invaluable tool for optimizing hydraulic fracturing stimulations and monitoring reservoir changes. The signal to noise ratio (SNR) of the recorded microseismic data varies ...
Full-waveform Based Microseismic Source Mechanism Studies in the Barnett Shale: Linking Microseismicity to Reservoir Geomechanics
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
Microseismic moment tensor (MT) contains important information on the reservoir and fracturing mechanisms. Difficulties arise when attempting to retrieve complete MT with conventional amplitude inversion methods if only ...
