Abstract
The paper presents results of the experimental study of hydraulic fractures formed by viscous liquid, which is initially generated from an initiating disk crack under compression stress conditions. Experimental dependences of crack geometries on injection velocity and viscosity of working fluid are obtained. The influence of working fluid properties on parameters of the developing cracks is analyzed.
