Natural or hydraulic fracture attributes such as planarity, path and connectivity affect fluid transport in reservoirs. Although many fracture models are based on two-dimensional approximations, accurately predicting fracture propagation geometry requires accounting for the three-dimensional aspects of fractures. We focus on the effects of fracture height on lateral propagation of vertical fractures using a 3-D displacement discontinuity model to investigate the curving path and the angle of intersection for overlapping fractures, and the evolution of stress intensity factor and energy release rate during propagation around the fracture periphery.
