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 ...
Downhole microseismic monitoring of hydraulic fracturing: a full-waveform approach for complete moment tensor inversion and stress estimation
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
Downhole microseismics has gained in popularity in recent years as a way to characterize hydraulic fracturing sources and to estimate in-situ stress state. Conventional approaches only utilize part of the information ...
