Hydraulic fracture and microseismicity in unconventional formations using a coupled stress-fracture-flow model
conference contribution
posted on 2023-05-23, 10:41 authored by Hongyuan LiuHongyuan Liu, Andrew ChanAndrew ChanHydraulic fracturing is the most important method of stimulating conventional oil and gas wells and unconventional shale gas and geothermal energy formations. In this paper, a stress-fracture-flow coupled model is developed on the basis of damage mechanics and Biot's seepage mechanics. The coupled model is first calibrated against a closed-form solution for hydraulic fracturing in a continuous rock mass and then used to simulate hydraulic fracturing stimulation of a discontinuous shale gas reservoir. It is concluded that the coupled model may shed new lights on hydraulic fracturing and associated microseismicity in stimulating the unconventional formations.
