Abstract
The article discusses development of two successive axially symmetric hydraulic fractures in line with well. Shapes of the surfaces of the second hydrofracture that propagates in the stress field initiated by the first hydrofracture are modeled, and the pressure for the second fracture to grow is calculated. The authors assess impact area of the first hydrofracture, analyze options of the second hydrofracture curving and derive formula of the second hydrofracture curving.
