Modeling propagation of multiple axially symmetrical hydrofractures

The article discusses growth of two successive axially symmetrical hydraulic fractures in line with a 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 cal...

Description
Summary:The article discusses growth of two successive axially symmetrical hydraulic fractures in line with a 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.
