Abstract
The authors analyze numerically growth of a cross fracture between two existing fractures under multiple directional hydrofracturing using chemically active mixtures. The scope of the studies embraces effect exerted by problem parameters, such as value and orientation of external compression field, rate of healing of fractures, size and intermediate spacing of fractures, on deviation of a fracture from its initial orientation. The results are meant for optimization of the local hydrofracturing method for steam-distribution and producing wells in low-gravity oil reservoirs.
