The EDGER forum historically has focused on interpretation of multicomponent data, direct shear vs. P-SV data, effects of fluids on seismic response, direct inverstion of p-p and p-sv data, imaging with a focus on p-p and p-sv data, and reservoir monitoring with seismic observations. In the last five years, the research has centered on seismic characterization of unconventional reservoirs, emphasizing shales and fracture zones, inversion of 3D and 4D seismic data for rock properties, rock physics modeling of heterogeneous and anisotropic materials, computational methods for wave propagation in complex media, and advanced imaging techniques. Recently published papers and abstracts are on this page.

TWO-WAY TRAVEL TIME ANALYSIS
FOR SEISMIC RESERVOIR CHARACTERIZATION
Two-way traveltime (TWT) is one of the most important seismic attributes for reservoir characterization. Erroneous analysis of TWT can lead to incorrect estimates of velocity models resulting in improper structural interpretation of the subsurface. TWT analysis starts with the most fundamental step of seismic data processing, namely, Normal Moveout (NMO) correction. NMO correction is generally performed in the offset-time (X-t) domain, by fitting a hyperbolic curve to the observed traveltimes corresponding to each reflection event. The commonly used NMO equation is valid within small offset and does not consider anisotropy - an effect commonly observed in fractured media. The performance of NMO correction depends on the quality of the data in the prestack domain and the underlying geology. In the plane wave (Tau-p) domain, the estimation of layer parameters can be done using exact equation for delay-time free from the approximation errors present in the X-t domain. In this domain a layer striping approach can also be used to account for the presence of multiple anisotropic and isotropic layers.
The primary goal of this thesis is to develop techniques for seismic data analysis that can be used for developing fractured reservoir models together with their uncertainties.
Main contributions of this research include:- Development of au-p domain NMO correction equation for VTI, HTI and orthorhombic media; a general equation is identi ed which reduces to VTI, HTI, elliptic anisotropy and isotropic media.
- Development of a critical angle re ectometry scheme in the Tau-p domain. This method analyzes critical slowness at each azimuth and relates it with the anisotropy parameters.
- Estimation of fracture attributes from reflection traveltime residuals for a reservoir from the Gulf of Mexico.
- Estimation of structural uncertainty in a Gulf of Mexico reservoir by combining traveltimes from seismic data and well log derived marker depths. We used a Markov-Bayes stochastic simulation to estimate structural uncertainty. Occurrence of signi cant uncertainty in several parts of the subsurface model may be attributed to using erroneous velocity model, presence of faults and fractures in the subsurface, and ignoring seismic anisotropy during data processing.

medium. Our developed method (red star) matches the exact
traveltime (green line) better than any other published method.

domain. This method is easy to implement for critical angle analysis
and anisotropy detection (when multi azimuth data is used)
Fig 3: Map of Structural uncertainty of a reservoir estimated in the time
domain (Traveltime uncertainty). Uncertainty is derived from standard
deviation of multiple realizations of the reservoir architecture.
Fig 4: Stochastic fracture simulation using RMO analysis. RMO is due to
processing anisotropic data (Fracture induced anisotropy) using isotropic
model. The map shows fracture strike direction at di erent spatial locations.

HIGH-ORDER FINITE ELEMENT METHODS FOR SEISMIC WAVE PROPAGATIONPurely numerical methods based on the Finite Element Method (FEM) are becoming increasingly popular in seismic modeling for the propagation of acoustic and elastic waves in geophysical models. These methods offer a better control on the accuracy and more geometrical exibility than the finite difference methods that have been traditionally used for the generation of synthetic seismograms. However, the success of these methods has outpaced their analytic validation. The accuracy of the FEMs used for seismic wave propagation is unknown in most cases and therefore the simulation parameters in numerical experiments are determined by empirical rules. The focus here is on two methods that are particularly suited for seismic modeling: the Spectral Element Method (SEM) and the Interior-Penalty Discontinuous Galerkin Method (IP-DGM).
The goals of this research are to investigate the grid dispersion and stability of SEM and IP-DGM, to implement these methods and to apply them to subsurface models to obtain synthetic seismograms. In order to analyze the grid dispersion and stability, I use plane wave analysis to obtain a generalized eigenvalue problem. I show that the eigenvalues are related to the grid dispersion and that, with certain assumptions, the size of the eigenvalue problem can be reduced from the total number of degrees of freedom to one proportional to the number of degrees of freedom inside one element.The grid dispersion results indicate that SEM of degree greater than 4 is isotropic and has a very low dispersion. Similar dispersion properties are observed for the symmetric formulation of IP-DGM of degree greater than 4 using nodal basis functions. The low dispersion of these methods allows for a sampling ratio of 4 nodes per wavelength to be used. On the other hand, the stability analysis shows that, in the elastic case, the size of the time step required in IP-DGM is approximately 6 times smaller than that of SEM. The results from the analysis are confirmed by numerical experiments performed using an implementation of these methods. The methods are tested using two benchmarks: Lamb's problems and the SEG/EAGE salt dome model.
Fig1: Superconvergence of SEM with respect to the sampling ratio. The slop
e of each curve represent the convergence rate of the method for a given degree. Similar superconvergence behaviors are observed for FEM with a consistent mass matrix and the symmetric formulation of IP-DGM.
Fig 2: Numerical results for Lamb's problem. The higher-degree
methods exhibit less dispersion, for a xed sampling ratio, and closely
approximate the analytic solution.
