Full-waveform Based Microseismic Event Detection and Signal Enhancement: The Subspace Approach
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
Microseismic monitoring has proven to be an invaluable tool for optimizing hydraulic fracturing stimulations and monitoring reservoir changes. The signal to noise ratio (SNR) of the recorded microseismic data varies ...
An improved method for hydrofracture induced microseismic event detection and phase picking
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
The ability to detect small microearthquakes and identify their P and S phase arrivals is a key issue in hydrofracture downhole monitoring because of the low signal-to-noise ratios. We apply an array-based waveform ...
