Full-waveform Based Microseismic Source Mechanism Studies in the Barnett Shale: Linking Microseismicity to Reservoir Geomechanics [PDF]

, 2013
Microseismic moment tensor (MT) contains important information on the reservoir and fracturing mechanisms. Difficulties arise when attempting to retrieve complete MT with conventional amplitude inversion methods if only one well is available.

Injection Induced Seismicity in Complex Fault Zone Architecture

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Modeling of injection‐induced seismicity plays a significant role in understanding the seismic risks associated with different anthropogenic activities including sub‐surface energy harvesting and CO2 ${\text{CO}}_{2}$ sequestration. Here we investigate multi‐cycle modeling of induced seismicity in a complex fault zone hosting a primary fault ...

Denoising method and application of microseismic signals for coal seam hydraulic fracturing based on deep neural network mode

Meitan xuebao
To address the challenges of low signal-to-noise ratio and difficulty in phase picking of microseismic signals induced by coal fracturing during hydraulic fracturing in coal seams, a deep neural network model based on a masking strategy is proposed (Mask

Goodbye Noise, Hello Signal! Improving Microseismic Monitoring in Noisy Environments

Proceedings, 2009
Over the last decade, Petroleum Development of Oman have deployed several microseismic monitoring systems. Due to the maturity of many of the oilfields in Oman, anthropogenic noise is in abundance. Given that the magnitude of some of the microseismic events can be as low as M = -3, noise can seriously hamper the detection and/or processing of such ...

Distinct Crustal Structure Across the Alpine Fault, New Zealand: Seismic Imaging of a Through‐Going Vertical Fault Beneath Its Central Section

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Alpine Fault (Aotearoa New Zealand) is a major plate boundary transform fault, that quasi‐periodically hosts large (M7‐8) to great (M8+) earthquakes. The fault is thought to be segmented with sections rupturing both individually and in combination.

Methods for Large Scale Hydraulic Fracture Monitoring

, 2013
In this paper we propose computationally efficient and robust methods for estimating the moment tensor and location of micro-seismic event(s) for large search volumes. Our contribution is two-fold.

Downhole microseismic signal denoising via empirical wavelet transform and adaptive thresholding

Journal of Geophysics and Engineering, 2018
Downhole microseismic data have the characteristics of low signal-to-noise ratio and high frequency, which pose a major challenge to noise attenuation.

Estimating Ice Cover on the Great Lakes Using Seismic Ambient Noise

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Lake ice impacts seismic noise on nearby seismometers, and therefore seismic observations can be used to monitor ice changes. However, the transfer function describing how lake‐microseism noise covaries with ice cover has not been quantified.

An improved empirical green function method to extract microseismic signals

Geodesy and Geodynamics, 2019
In mining, reservoir impoundment and hydraulic fracturing exploitation, the induced microseismic clusters may present complex waveforms at receivers since the individual events generally arrive very close. And the routine methods for arrival picking are insufficiently efficient due to these strong influences.
