Abstract
The article describes numerical modeling of growth of five successive hydraulic fractures in the direction transverse to the well, in plane and axisymmetric elastic problems, under assumption of perfect breakdown fluid. The zone of influence of the existing created fractures on the newly initiating hydrofractures is defined, and the pressure for a new fracture to grow is evaluated. Parameters governing distortion of fractures are determined. The calculations in the framework of the plane and axisymmetric problems are compared.
