Differences between downhole and surface micro-seismic monitoring

Publikováno v: Mining Science, Vol 22, Pp 65-73 (2015)

The article presents usage of microseismic monitoring for location of microseismic events in polish geological conditions. For location of one synthetic microseismic event, two methods of acquisition were applied: surface and downhole monitoring arra

Correlation analysis of petrophysical parameters within the main dolomite sedimentation zones on the Grotów peninsula

Autor: Paweł Wandycz, Eryk Święch

Publikováno v: Mining Science, Vol 22, Pp 45-54 (2015)

The study area in geological sense is located on the Grotów peninsula within Gorzów Block in north-western part of Poland, on the border of Fore-Sudetic monocline and Szczecińska Through. In that area two generalized sedimentary zones were recogni

Determination of seismic wave attenuation based on acoustic full waveforms

Autor: Eryk Święch, Paweł Wandycz

Publikováno v: Mining Science, Vol 22, Pp 55-63 (2015)

The loss of elastic energy to the medium can be quantified by the quality factor Q. Acoustic full waveforms log from Winna Góra1 borehole were used to estimate P-wave quality factor. Data used in this paper were analyzed with usage of GeoWin softwar

Estimation of the quality factor based on the microseismicity recordings from Northern Poland

Autor: Eryk Święch, Tomasz Maćkowski, Andrzej Pasternacki, Miłosz Wcisło, Leo Eisner, Paweł Wandycz

Publikováno v: Acta Geophysica. 67:2005-2014

We use the peak frequency method to estimate effective P- and S-wave quality factors (QPandQS) based on the recorded waveforms of microseismic events. We analyze downhole datasets recorded during the hydraulic stimulation of the two unconventional ga

Aggressive mimicry in a coral reef fish: The prey's view

Autor: Michele E. R. Pierotti, Paweł Wandycz, William T. Wcislo, Juliana H. Tashiro, Anja Rebelein, W. Owen McMillan, Anna Wandycz, Armando Castillo, Vitor H. Corredor, Ellis R. Loew

Publikováno v: Ecology and Evolution

Since all forms of mimicry are based on perceptual deception, the sensory ecology of the intended receiver is of paramount importance to test the necessary precondition for mimicry to occur, that is, model‐mimic misidentification, and to gain insig

Estimating microseismic detectability of the surface-monitoring network using downhole-monitoring array

Autor: Denis Anikiev, Tomasz Maćkowski, Andrzej Pasternacki, Leo Eisner, Eryk Święch, Paweł Wandycz

Publikováno v: Interpretation

We have analyzed microseismic monitoring data sets obtained from the surface and downhole-monitoring arrays recorded during the first experiment of hydraulic fracturing in Poland. Using the downhole-monitoring network, we were able to record and loca
