Shear-wave splitting analysis of downhole microseismic data for reservoir characterization of the Montney Formation, Pouce Coupe, Alberta

摘要

Following the symbiotic emergence of hydraulic frac-ture stimulation and microseismic monitoring, the phenomenon of shear-wave splitting is now being measured from completions operations. This study focuses on the downhole microseismic survey acquired at Pouce Coupe during the hydraulic fracture treatment of three horizontal wells. Microseismic shear-wave splitting analysis was performed to better constrain the physical rock properties of the Montney Formation. A strong temporal correlation was also observed between shear-wave splitting measurements and completion data providing insight into the response of the reservoir during hydraulic stimulation.
