Radon transform-based microseismic event detection and signal-to-noise ratio enhancement
(Elsevier Science, 2015-02)
We present an adaptive filtering method to denoise downhole microseismic data. The methodology uses the apex-shifted parabolic Radon transform. The algorithm is implemented in two steps. In the first step we apply the ...
Microseismic event location using global optimization algorithms: An integrated and automated workflow
(Elsevier Science, 2018-02)
We perform the location of microseismic events generated in hydraulic fracturing monitoring scenarios using two global optimization techniques: Very Fast Simulated Annealing (VFSA) and Particle Swarm Optimization (PSO), ...
A simple energy-based strategy for sensor orientation in borehole microseismic monitoring
(IOP Publishing, 2019-02)
Accurately determining the orientation of borehole sensors is of paramount importance for microseismic monitoring applications. We calculate the relative bearing angle that allows the orientation of borehole receivers for ...
Inversion of Seismic Anisotropic Parameters Using Very Fast Simulated Annealing with Application to Microseismic Event Location
(Asociación Argentina de Mecánica Computacional, 2016-11)
The study and interpretation of hydraulically stimulated regions, such as certain unconventional hydrocarbon reservoirs (e.g. Vaca Muerta Formation, Neuquén, Argentina), requires the accurate location of the induced ...
