..., there is a continuous decrease in the During the fracturing test of siltstone samples, the expansion of vertical fracture leads to the presence of 3 horizontal fractures in the middle of samples, consistenting with the tensile fracture models (see Figure 5 (a) and (b Unlike the nearly homogenous siltstone, shale...

... the sensing assembly detected the initiation and growth of fractures as pressure was incrementally increased. The distributed nature of the measurement allowed for detecting a pre-existing horizontal fracture between formations, detecting new bi-wing vertical fractures in each of the two formations...

... plane where the laterals lie and forms a fracture network with one main horizontal fracture connecting multiple vertical fractures; the breakdown and injection pressure decrease with the lateral length and count increasing; increasing the lateral length enlarges the horizontal fracture area...

... on the interaction between hydraulically induced fractures and pre-existing natural fractures. The fracture interaction and propagation geometry within pre-existing fractures is still not well studied in laboratory-scale experiments. hydraulic fracturing Simulation horizontal fracture fracture propagation...

... interface fracture curvature horizontal fracture diffusion-limited aggregation hele-shaw cell interface ABSTRACT: We consider the use of a modified diffusion-limited aggregation.(DLA) process to model immiscible viscous displacements in rough-walled fractures. We include the effects of local...
