Effect of data sampling on the location accuracy of high frequency microseismic events
نویسنده
چکیده
Data sampling and its effect on the microseismic events locations and in particular azimuth measurements is the objective of this study. The study focuses on how Principal Component Analysis efficiency [2] depends on the relationship between dominant frequency and sample rate using synthetic events with white noise. Moreover, the resistance of event location methodology to the sampling rate and to the number of geophones is studied for different dominant frequencies. The results show that higher sampling rate allows for the usage of higher frequency harmonics, leading to improved location accuracy for microseismic events.

There is substantial debate over the mental representation of regular past tense forms in both first language (L1) and second language (L2) processing. Specifically, the controversy revolves around the nature of morphologically complex forms such as the past tense –ed in English and how morphological structures of such forms are represented in the mental lexicon. This study focuses on the resul...

In the Iranian economy, which has experienced various sanctions, it was necessary to anticipate macroeconomic variables when imposing new sanctions. On the other hand, in the context of sanctions, it is possible to make a more accurate assessment of economic policies in order to be able to respond in a timely manner to these shocks and the need for appropriate planning and security against them...
متن کاملAutomated microseismic event location using Master-Event Waveform Stacking
Accurate and automated locations of microseismic events are desirable for many seismological and industrial applications. The analysis of microseismicity is particularly challenging because of weak seismic signals with low signal-to-noise ratio. Traditional location approaches rely on automated picking, based on individual seismograms, and make no use of the coherency information between signal...

In the present study, an investigation was carried out on Parvadeh coal mine in Tabas, Iran, to survey the effect of fractures on unusual methane gas emission in coal mines. This coal mine was chosen for investigating because of its high methane gas content in the coal body and available data from sensors in desired locations. Gas concentration monitoring programs were carried out at the mine s...
