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 ...
Efficient characterization of uncertain model parameters with a reduced-order ensemble Kalman filter
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
Spatially variable model parameters are often highly uncertain and di fficult to observe. This has prompted the widespread use of Bayesian characterization methods that can infer parameter values from measurements of related ...
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 ...
Finite-Difference Simulations of Time Reversed Acoustics in a Layered Earth Model
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2007)
Traditionally an earthquake is located by using the arrival times of P and S phases. This uses only a limited portion of the information on a seismogram. A large part of the information carried by the waveform is not used. ...
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 ...
