Abstract
The authors analyze numerically propagation of hydraulic fractures from a circular hole boundary under viscous fluid injection in plane deformation condition, considering influence of the fluid viscosity and elastic characteristics. The approximate solution is compared with the recent numerical calculations of exact formulated problem. Effect of configuration of incipient hydraulic fractures on development of the overall hydrofracturing pattern is analyzed, and stable growth conditions for several long fractures are found.
