Study of seismic activity in the Haiyuan-Liupanshan region using automated microseismic detection techniques

Geomatics, Natural Hazards & Risk
Using continuous waveform data from 27 fixed seismic stations in Ningxia spanning nearly a decade from 2013 to September 2022, the automatic detection matching method (PALM) was employed to capture 34,373 seismic events across the region, which is twelve

Real time identification of microseismic events based on ridge regression improved normative variable analysis

Gong-kuang zidonghua
The identification of microseismic events is the foundation of microseismic monitoring in coal mines. Most existing microseismic monitoring technologies are developed based on the variation law of single physical quantities, which can easily lead to ...

Microseismic reflection imaging

, 2013
Das Ziel dieser Arbeit ist es das Repertoire der Anwendungsmöglichkeiten mikroseismischer Daten zu erweitern und für die reflexionsseismische Abbildung zu nutzen. Hierbei werden mikroseismische Ereignisse als äquivalent zu aktiven seismischen Quellen behandelt sowie die korrespondierenden Wellenfelder als seismische Reflexionen.

Microseismic moment-tensor inversion

, 2011
It is common practice in the oil and gas industry to use a single vertical well with limited number of geophones to monitor the microseismicity induced by hydraulic fracture treatment. In this thesis, I have employed a synthetic and stochastic modeling approach to investigate the effects of monitoring geometry and noise on inverting recorded P- and S ...
