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 array. Downhole microseismic monitoring is a technique of recording induced seismicity using receivers placed in the monitoring well near to the treatment well. In case of surface monitoring receivers are placed at the surface. For determination of hypocenter location probability density function was used. Based on provided analysis it is concluded that for polish conditions it is better to use downhole microseismic monitoring. Event located with usage of this technique was located correctly and uncertainty of this location was lower.
