Shear-wave splitting and attenuation analysis of downhole microseismic data for reservoir characterization of the Montney Formation, Pouce Coupe, Alberta
Two microseismic waveform analysis methods were performed for reservoir characterization of the Montney Formation at Pouce Coupe, Alberta. Microseismic events recorded on two downhole arrays during the hydraulic fracture stimulation of three production wells formed the dataset for both methods. The first method involved the calculation of shear-wave attenuation factors through a comparison of observed and expected P/Sh amplitude ratios. The method was anticipated to help infer the presence of fluid-filled fractures however a number of limitations were identified. The assumption of a single ...
