Study on Initiation Mechanisms of Hydraulic Fracture Guided by Vertical Multi-radial Boreholes

The conventional hydraulic fracturing fails in the target oil development zone (remaining oil or gas, closed reservoir, etc.) which is not located in the azimuth of maximum horizontal in situ stress of available wellbores. The technology of …

Über diese Zeitschrift

Rock Mechanics and Rock Engineering covers the experimental and theoretical aspects of rock mechanics, including laboratory and field testing, methods of computation and field observation of structural behavior. The journal maintains the strong link between engineering geology and rock engineering, providing a bridge between fundamental developments and practical application. Coverage includes case histories on design and construction of structures in rock such as underground openings, large dam foundations and rock slopes.

Fields of interest include rock mechanics in all its varied aspects including laboratory testing, field investigations, computational methods and design principles. The journal also reports on applications in tunneling, rock slopes, large dam foundations, mining, engineering and engineering geology.
