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 ...
A Bayesian framework for fracture characterization from surface seismic data
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
We describe a methodology for quantitatively characterizing the fractured nature of a hydrocarbon or geothermal reservoir from surface seismic data under a Bayesian inference framework. Fractures provide pathways for fluid ...
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 ...
Nonlinear Frechet derivative and its De Wolf approximation
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
We introduce and derive the nonlinear Frechet derivative for the acoustic wave equation. It turns out that the high order Frechet derivatives can be realized by consecutive applications of the scattering operator and a ...
Efficient Double-Beam Characterization for Fractured Reservoir
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012-06)
We proposed an efficient target-oriented method to characterize seismic properties of fractured reservoirs: the spacing between fractures and the fracture orientation. Based on the diffraction theory, the scattered wave ...
