PLANNING, CONFIGURATION AND USEFULNESS OF MICROSEISMIC MONITORING ON EASTERN-EUROPE PLATFORM – EXAMPLE FROM EAST POMERANIA
Last modified: 2017-09-11
Abstract
The microseismic monitoring is a method of monitoring of fracture propagation during hydraulic fracturing process.The method uses array of geophones to localize micro tremors induced by liquid pumped underground at high rate andpressure. The acquired information helps to optimize fracturing process and prevents fracture growth to aquifer levels. It wasproved to be useful on several unconventional hydrocarbon reservoirs in the USA. Conducted investigation was aimed atevaluation of the possibility of using the technology on Polish unconventional reservoirs. In order to stand better chances ofsuccess the analysis of several variants of monitoring was made. East Pomerania geological structure was compared to similarstructures in the USA. With this knowledge, financially feasible configuration was selected. The array of geophones wasdispatched around the drilling site and data acquisition was performed. The present paper is mainly focus on geologicalstructure, hardware selection, damping factor and noise level analysis. The usefulness of used receiver configuration is alsoassessed.
