... networks for various loading conditions. We propose a method enabling the calculation of hydraulic fracturing fluid injection pressure from the obtained numerical conditions of loading and regional stress in the target reservoir rock. Results of numerical simulation and recalculation of the obtained...

... of flow rate/permeability have been achieved on both samples through fracture shear slip induced by elevating injection pressure. It is shown that ∼100 times increase in flow rate was induced by a ∼0.1 mm scale of shear slip on the two cylindrical shale samples (with ∼38 mm diameter). The permeability...

Three different cyclic injection treatments are carried out: (1) Pre-breakdown cyclic injection fracturing where fluid is injected in cyclic manner till breakdown, (2) Post-breakdown cyclic injection which...

..., an injection pressure equal to the initial reservoir pressure is recommended. Using low injection pressure, S hmin is found out to be lowest in fractures, which may make infill well fractures tend to propagate into and hit the parent well fractures. However, if injection pressure is increased to larger than...

.... This indicates that shear slippage along weak lamination interfaces does not help propagate hydraulic fractures. Instead, it dissipates energy and elevates injection pressure, in some cases well above the overburden. Perforation patterns play important roles in formation breakdown and fracture geometry near...

In addition, fluid flow through shale fractures under different values of confining stress and injection pressure were examined to investigate the stress-dependent permeability of shale fractures. The hydrostatic flow tests show that flow rate linearly rises with the increase of injection, while...

Estimation of pressure losses along the well for the common casing diameters and fracturing fluids indicates that a high pressure gradient develops along the well during refracturing. It results in significantly higher injection pressures at the heel than...
