RESEARCH: Pushing the limits of seismic resolution

In the past decade, efforts have increased to search for hydrocarbons in difficult areas and in unconventional and fractured reservoirs. This search prompted acquisition of multi-azimuth and wide-azimuth datasets and development of processing algorithms using more complete physics of wave propagation. Currently the primary focus of EDGER is on advancement in quantitative seismic interpretation (QSI). This involves development of advanced techniques for high-resolution estimates of reservoir properties by integrating disparate datasets observed at multiple scales. The scope of research encompasses three major themes:

  • Development of new techniques for seismic imaging and inversion
  • Development of new rock physics models and adaptation of existing rock physics models to a particular field under investigation
  • Integration of seismic inversion and rock physics models using novel statistical approaches and validation with field datasets.

Our imaging and inversion efforts include development of new theory and numerical algorithms for forward seismic modeling that are computationally efficient and accurate. These are used in full waveform imaging and inversion. Inversion for reservoir parameter estimation will be carried out using hybrid Markov Chain Monte Carlo methods. Effective medium models are being tested by computing the seismic responses of realistic rock models based on distributions of rock properties. We are developing new data integration techniques using geostatistical methods and Bayesian analysis.

    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.

    HIGH-ORDER FINITE ELEMENT METHODS FOR SEISMIC WAVE PROPAGATION

    Purely 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.

    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.

    methods exhibit less dispersion, for a xed sampling ratio, and closely
    approximate the analytic solution.
