Abstract

Some results of laboratory simulation of microseismicity due to pore pressure change during an<br>oil-field development are considered. It was found that acoustic pulses registered during<br>injection have significantly lower frequencies than pulses registered during pore pressure<br>decrease. The relation between porosity and uniaxial strength of a model sample was found to<br>be exponential. The relation between slope of magnitude-frequency dependence and sample<br>strength was studied. The results can be used for estimation of a reservoir average<br>strength/porosity and for correct interpretation of passive seismic monitoring data during hydro<br>fracturing
