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 ...
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 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 ...
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 ...
Estimation of fracture compliance from tubewaves generated at a fracture intersecting a borehole
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
Understanding fracture compliance is important for characterizing fracture networks and for inferring fluid flow in the subsurface. In an attempt to estimate fracture compliance in the field, we developed a new model to ...
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 ...
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 ...
Fracture characterization from attenuation of Stoneley waves across a fracture
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
Fractures contribute significantly to the permeability of a formation. It is important to understand the fracture distribution and fluid transmissivity. Though traditional well logs can image fractures intersecting the ...
Experimental Studies of Reflections from Single and Multiple-Fractures Using Lucite Models
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
Laboratory acoustic measurements are performed with Lucite fracture models to understand the reflection characteristics of a seismic wave in a fracture zone. The fracture models include single fracture, dual fracture, and ...
