.... Often carried out at depths of kilometers, the fracturing process cannot be observed directly. Early analyses of the hydraulic fracturing process assumed that a single fracture developed symmetrically from the packed off-pressurized interval of a borehole in a stressed elastic continuum. It is now...

... shows that the main reason for the poor progress is the exploitation concept being applied in all major projects since the early 1980´th. Until than the basement had been regarded as a competent rock mass and the leading exploitation scheme was to connect two inclined boreholes by a number of parallel...

... the conglomerate from vertical boreholes drilled from the surface. The measurements and trials were designed to determine the in situ principal stresses, the hydraulic fracture orientation and growth rate, and whether the fractures could be extended as essentially parallel fractures to a radius of at least 30 m...

... (typical) Table 1. Adelaide Black Granite material properties. Four hydraulic fractures were grown in each block, as shown in Figure 1. The fractures were grown one at a time beginning with the deepest fracture and working incrementally towards the top of the borehole. The experimental setup used CSIRO s...
