Shapes of Hydraulic Fractures in the Vicinity of Borehole-and-Branch Hole Junction

The authors describe numerical investigations of hydraulic fractures in boreholes with branches (intersecting boreholes). The directions of growing fractures were determined in the static problem solution by the criterion of maximum tangential stresses and in the quasi-static three-dimensional formu...
