Fracture Spacing and Orientation Estimation from Spectral Analyses of Azimuth Stacks
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2005)
Discrete, vertically aligned fracture systems impart one or more notches in the spectral ratios of stacked reflected seismic traces. This apparent attenuation is due to the azimuth dependant scattering introduced by the ...
Spatial Orientation And Distribution Of Reservoir Fractures From Scattered Seismic Energy
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2005)
We present the details of a new method for determining the reflection and scattering characteristics of seismic energy from subsurface fractured formations. The method is based upon observations we have made from 3D finite ...
Fracture Density Estimation Using Spectral Analysis of Reservoir Reflections: A Numerical Modeling Approach
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2003)
We use a 3-D finite difference numerical model to generate synthetic seismograms from a simple fractured reservoir
containing evenly spaced, discrete, vertical fractures. The fractures are represented using a single column ...
Spatial Orientation and Distribution of Reservoir Fractures from Scattered Seismic Energy
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2006)
We present the details of a new method for determining the reflection and scattering characteristics of seismic
energy from subsurface fractured formations. The method is based upon observations we have made from 3D ...
Spatial Orientation And Distribution Of Reservoir Fractures From Scattered Seismic Energy
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2004)
Expanded details and additional results are presented using a new method (Willis et al, 2003) for determining the reflection and scattering characteristics of seismic energy from subsurface fractured formations. The method ...
Characterization of Scattered Waves from Fractures by Estimating the Transfer Function Between Reflected Events Above and Below Each Interval
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2003)
It is important to be able to detect and characterize naturally occurring fractures in reservoirs using surface seismic
reflection data. 3D finite difference elastic modeling is used to create simulated surface seismic ...
