... and about 33% of clusters are ineffective and do not contribute to production (Miller et al., 2011; Wheaton et al., 2014). Besides, detection of frac hits and well inference also imply non-uniform fracture growth (Rimedio et al., 2015). To improve fracturing efficiency and promote more uniform fracture...

A cohesive zone model is used for fracture propagation along with a dynamic and adaptive meshing procedure. We investigate the effect of fluid...

... ABSTRACT: Controlled fracture geometry is one of the most important criteria that measure the success of a hydraulic fracturing treatment. Typical stress conditions often lead to generation of a planar vertical fracture. Even for this simple geometry, fracture growth in a multilayered rock...
