Seismic characterization of fractured reservoirs using 3D double beams
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
We propose an efficient target-oriented method to characterize seismic properties of fractured reservoirs: the spacing between fractures and the fracture orientation. We use both singly scattered and multiply scattered ...
Predicting stress-induced anisotropy around a borehole
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
Formation elastic properties near a borehole may be altered from their original state due to the stress concentration around the borehole. This could result in a biased estimation of formation properties but could provide ...
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 ...
Seismic characterization of reservoirs with variable fracture spacing by double focusing Gaussian beams
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
Fractured reservoirs account for a majority of the oil production worldwide and often have low recovery rate. Fracture characterization is important in building reservoir flow models for enhanced oil recovery. Information ...
Fluid Flow Property Estimation from Seismic Scattering Data
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
We present a methodology for relating seismic scattering signals from fractures to the fluid permeability field of the fracture network. The workflow is used to interpret seismic scattering signals for the reservoir ...
Reservoir fracture characterizations from seismic scattered waves
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
The measurements of fracture parameters, such as fracture orientation, fracture density and fracture compliance, in a reservoir is very important for field development and exploration. Traditional seismic methods for ...
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 ...
Sensitivity analysis of fracture scattering
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
The understanding of seismic scattering of a finite fracture
is very important in reservoir fracture characterizations, but
the analytical solution of this problem is not available. Thus,
in this paper, we present an ...
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 ...
A robust method for fracture orientation and density detection from seismic scattered energy
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
The measurements of fracture parameters, such as fracture orientation, fracture density and fracture compliance, in a reservoir is very important for field development and exploration. Traditional seismic methods for ...
