Pressure characteristics and performance of multi-stage fractured horizontal well in shale gas reservoirs with coupled flow and geomechanics

摘要

Multi-stage hydraulic fracturing is a crucial well completion strategy in unconventional reservoirs to improve hydrocarbon production. Reservoir performance and pressure characterization in multi-stage fracture development considering elastic rock mechanics are not systematically discussed in the literature. This work considers effects of elastic rock mechanics and hydraulic fractures in unconventional reservoir development scenarios using a numerical model with coupled fluid flow and geomechanics.
