Monitoring hydraulic stimulation using telluric sounding
The telluric sounding (TS) method is introduced as a potential tool for monitoring hydraulic fracturing at depth. The advantage of this technique is that it requires only the measurement of electric fields, which are cheap and easy when compared with magnetotelluric measurements. Additionally, the transfer function between electric fields from two locations is essentially the identity matrix fo...
متن کاملBis(homopiperazine-1,4-diium) cyclotetraphosphate–telluric acid (1/2)
The title compound, 2C(5)H(14)N(2) (2+)·P(4)O(12) (4-)·2Te(OH)(6), involves doubly protonated homopiperazinium cations, cyclo-tetra-phosphate anions and telluric acid mol-ecules. The framework possesses very large channels wherein the organic cations reside. A network of O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds consolidates the crystal packing.
متن کاملMinimizing Strong Telluric Absorption in Near Infra-red Stellar Spectra
We have obtained high resolution spectra (R ∼ 25000) of an A star over varying airmass to determine the effectiveness of telluric removal in the limit of high signal to noise. The near infra-red line He I at 2.058μm, which is a sensitive indicator of physical conditions in massive stars, supergiants, H II regions and YSOs, resides among pressure broadened telluric absorption from CO2 and water ...
متن کاملAn Effective Evaluation Function for Ica to Separate Train Noise from Telluric Current Data
Irregular changes of electric currents called Seismic Electric Signals (SESs) are often observed in Telluric Current Data (TCD). Recently, detection of SESs in TCD has attracted notice for shortterm earthquake prediction. Since most of the TCD collected in Japan is affected by train noise, detecting SESs in TCD itself is an extremely arduous job. The goal of our research is automatic separation...
متن کاملSeparation of Train Noise and Seismic Electric Signals from Telluric Current Data by Ica
Recently, detection of seismic electric signals (SESs) in telluric current data (TCD) observed using the VAN method has attracted notice for short-term earthquake prediction. However, since most of the TCD collected in Japan is affected by train noise, detecting SESs in TCD itself is an extremely arduous job. The goal of this research is to derive a method for detecting SESs, which is difficult...
