We have evaluated arrival-time picking algorithms for downhole microseismic data. The
picking algorithms that we considered may be classified as window-based single-level …

We have developed three methods for the automatic picking of first breaks that can be used
for marine, dynamite, or vibroseis shot records: a modified Coppens's method, an entropy …

Arrival time picking is a critical step in the analysis of geophysical data. This study aims at
improving the standard short-term-average/long-term-average (STA/LTA) method using soft …

Manually picking regularly and densely distributed first breaks (FBs) are critical for shallow
velocity-model building in seismic data processing. However, it is time consuming. We …

Featured Application Acoustic emission signal detection, seismology, ultrasonic inspections,
non-destructive condition monitoring. Abstract A novel methodology is proposed to enhance …

A discrete wavelet transform (DWT) and short time average to long time average (STA/LTA)-
based Kurtosis algorithm (WS/LK method) is proposed to pick the arrival time of the P-phase; …

Picking the first breaks from seismic data is often a challenging problem and still requires
significant human effort. We have developed an iterative process that applies a traditional …

The application of neural networks to seismic first break (FB) picking research has been
developed for many years. Numerous multitrace FB picking methods based on convolutional …

ABSTRACT A novel approach is presented to identify first breaks on shot gathers, using a
combination of machine learning and traditional attribute based computation. A modern …

Micro-seismic P-phase arrival picking is an elementary step into seismic event location,
source mechanism analysis, and seismic tomography. However, a micro-seismic signal is …
