Converted Phase Elastic Migration Velocity Analysis
Shabelansky, Andrey Hanan; Malcolm, Alison E.; Fehler, Michael; Shang, Xuefeng; Rodi, William L. (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 ... -
Data-Driven Estimation of the Sensitivity of Target-Oriented Time-Lapse Seismic Imaging to Source Geometry
Shabelansky, Andrey Hanan; Malcolm, Alison E.; Fehler, Michael (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 ... -
Monitoring Seismic Attenuation Changes Using a 4D Relative Spectrum Method in Athabsca Heavy Oil Reservoir, Canada
Shabelansky, Andrey Hanan; Malcolm, Alison E.; Fehler, Michael (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 ... -
Seismic imaging of hydraullically-stimulated fractures: A numerical study of the effect of the source mechanism
Shabelansky, Andrey Hanan; Malcolm, Alison E.; Fehler, Michael; Bakku, Sudhish Kumar (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 ... -
Visibility Analysis using Reverse Time Wave Sensitivity for Time-Lapse Target-Oriented Imaging
Shabelansky, Andrey Hanan; Malcolm, Alison E.; Fehler, Michael (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 ...
