Sensitivity of time lapse seismic data to the compliance of hydraulic fractures
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
We study the sensitivity of seismic waves to changes in the fracture normal and tangential compliances by analyzing the fracture sensitivity wave equation, which is derived by differentiating the elastic wave equation with ...
Joint flow-seismic inversion for characterizing fractured reservoirs: theoretical approach and numerical modeling
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
Traditionally, seismic interpretation is performed without any account of the flow behavior. Here, we present a methodology to characterize fractured geologic media by integrating flow and seismic data. The key element of ...
Finite Difference Elastic Wave Modeling Including Surface Topography
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
Surface topography and the weathered zone (i.e., heterogeneity near the earth’s surface) have great effects on elastic wave propagation. Both surface waves and body waves are contaminated by scattering and conversion by ...
Modeling of acoustic wave scattering from a two-dimensional fracture
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
In this paper, we model the acoustic scattering from a two dimensional fracture that is simulated by two different physical models. We calculate the scattering from the fractures with different properties based on these ...
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 ...
SH Wave Scattering from Fractures using Boundary Element Method with Linear Slip Boundary Condition
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
A boundary element method (BEM) combined with a linear slip boundary condition is proposed to calculate SH wave scattering from fractures. The linear slip boundary condition was proposed by Schoenberg (1980) to model elastic ...
