Influence Evaluation of Sensor Coordinate Error on Microseismic Source Location
Frontiers in Earth Science, 2022 In microseismic (MS) source localization, it is usually assumed that the sensor coordinates are accurate. However, there are generally measurement errors for the sensor coordinates in practical engineering, which severely affect the location accuracy of ...

Effect of Velocity Anisotropy in Shale on the Acoustic Emission Events Matching and Location
Frontiers in Earth Science, 2022 Accurate source event location is important in fracturing monitoring and characterization. Velocity anisotropy has a great influence on both events matching and events location. Failure to take into account the velocity anisotropy can lead to huge errors

Transfer learning for self-supervised, blind-spot seismic denoising
Frontiers in Earth Science, 2022 Noise is ever present in seismic data and arises from numerous sources and is continually evolving, both spatially and temporally. The use of supervised deep learning procedures for denoising of seismic datasets often results in poor performance: this is

Coalescence microseismic mapping [PDF]
Geophysical Journal International, 2013 Earthquakes are commonly located by linearized inversion of discrete arrival time picks made from signals recorded at a network of seismic stations. If mis-picks are made, these will contribute to the location, therefore causing potential bias. For data recorded by a dense seismic array, direct imaging methods can be applied instead.
