...) hydraulic fracture model to simulate fracture propagation under a production-disturbed stress field. The underlying effects of horizontal and vertical offsets on child-well fracturing and stimulation efficacy were analyzed through a detailed characterization of interwell fracture networks. Case studies...

... heterogeneity influences the rock mass stiffness and fracture propagation rates and thus needs to be considered. In this paper we focus on the role of overburden and underburden mechanical properties and toughness contrast on growth of a hydraulic fracture. In view of the 3D problem complexity, we use a fully...

Under different in-situ stress configurations and initial fracture orientations (flaws around wellbores are represented by the initial fractures), several patterns of hydraulic fracture propagation around the wellbores are recognized. It is found that the stress...
