Steady state permeability is calculated using Darcy s equation, shown below in Eq. (1). Q=kAL) P (1) Where Q is the flowrate (cc/min...

... 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...

..., 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...

... polyacrylamide (HPAM) polymer was selected and the initial target viscosity was set at 45 centipoise. Polymer injection rate was set at 2200 bbl/day for one injector (J-23A) and 1200 bbl/day for the other (J-24A) based on production voidage. Injection pressure was controlled below or slightly higher than...

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.
