Monitoring Seismic Attenuation Changes Using a 4D Relative Spectrum Method in Athabsca Heavy Oil Reservoir, Canada
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
Heating heavy oil reservoirs is a common method for reducing the high viscosity of heavy oil and thus increasing the recovery factor. Monitoring these changes in the reservoir is essential for delineating the heated region ...
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 ...
Seismic imaging of hydraullically-stimulated fractures: A numerical study of the effect of the source mechanism
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
We present a numerical study of seismic imaging of hydraulically stimulated fractures using a single source from an adjacent fracturing-process. The source is either a point force generated from the perforation of the ...
Data-Driven Estimation of the Sensitivity of Target-Oriented Time-Lapse Seismic Imaging to Source Geometry
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
The goal of time-lapse imaging is to identify and characterize regions in which the
earth's material properties have changed between surveys. This requires an effective deployment of sources and receivers to monitor the ...
Comparison of microearthquake locations using seismic interferometry principles
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
Mapping, localization, and general characterization of problems in reservoir fracture systems is one of the most important in oil, gas, and geothermal energy production. One way to study and monitor these fracture systems ...
Advanced 3D Geophysical Imaging Technologies for Geothermal Resource Characterization
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
We describe the ongoing development of joint geophysical imaging methodologies for geothermal site characterization and demonstrate their potential in two regions: Krafla volcano and associated geothermal fields in ...
Scholte waves generated by seafloor topography
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
Seafloor topography can excite strong interface waves called Scholte waves that are often dispersive and characterized by slow propagation but large amplitude. This type of wave can be used to invert for near seafloor shear ...
