... and the effect of non- planar fracture growth (e.g. fracture turning) is not considered in these models. In addition, the presence of pre-existing natural fractures in the reservoir and the interaction between a propagating hydraulic fracture and pre-existing natural fractures is ignored in their analysis...

... as designed is vital for an effective preconditioning program. Monitoring hydraulic fractures growth and shape can be completed using surface based tiltmeters (Griffin et al. 2000; Lecampion et al. 2005). Tiltmeters are sensitive ground deformation devices that can measure tilt angle change to nanoradian...

However, fracture growth is relevant to a range of other applications, including hydro-geo-mechanical modeling of processes occurring in or near reservoirs, mines, and nuclear waste repositories. Fracture growth within quasi-brittle rocks involves propagation and interaction across scales. Growth...
