- Stochastic Modeling of Discrete Fracture Networks

- Microseismic processing

- Inversion for seismic source mechanisms

Research Summary:

My current research focuses on developing efficient numerical methods to optimize seismic wave propagation applying the Finite Element Method. The approach relies on implementing special basis functions, in addition to the traditional Lagrange polynomials, that are extracted from known analytical solutions. The main application focuses on capturing the behavior of seismic waves with small wavelengths without the need of excessive mesh refinement, as in the case of media with high velocity contrast (ex. karstic environments) and high frequency sources (ex. microseismicity). This application is being developed in C++, Linux environment, using the open source library Deal.II.

Other research experience includes stochastic modeling of Discrete Fracture Networks (DFN) constrained by field data, application of inversion techniques to estimate source mechanisms (rapture mode) for microseismic events, as well as studies on the effect of fracture characterization uncertainties on fluid production. These projects were developed in MATLAB and Mathematica. The main goal of the stochastic DFN modeling was to create possible realizations of fracture systems induced by hydraulic fracturing. The modeling was constrained by the location of microseisms and core data analysis. The goal of the source mechanisms estimation was to further constrain the generation of DFN by finding rapture parameters (strike, dip and rake) of induced fractures. In this case, inversion of P-S amplitude by least squares was performed. For the uncertainty analysis, several DFN realizations were created to obtain a cumulative density function of DFN area, from which different percentiles of fluid production were estimated. In this case, to improve the computational efficiency, an optimized sampling technique, Latin hypercube, was implemented
