Sensitivity analysis indicated that in a reservoir with more natural fractures, hydraulic fracture length plays a more significant role, and in a reservoir with fewer natural fractures, both hydraulic fracture length and opening are highly influential.
The rectangles in yellow signify the hydraulic fracture length and location in the model (invisible due to local grid refinement).
The goal was to investigate the effect of hydraulic fracture length and aperture on the production rate from both reservoirs.
The second is the viscosity dominated PKN case, wherein the minimum input power when the hydraulic fracture length is much greater than both the fracture height and spacing occurs when the spacing is around 2.5 times the fracture height.
Hydraulic fracture half length, ft. Gas density, g/cm3.
Radial well drilling by hydraulic jetting, whose length is up to 100 m and diameter is 25 50 mm, has been widely applied and has achieved positive effects,(Ma et al. 2005).
A global catalytic kinetic step provides excellent agreement (at temperatures below 950 K) between the measured and predicted fuel conversion, over a wide range of parameter variation (channel hydraulic diameter and length, pressure, and inlet temperature).
Based on the third type HEM, which has an inertia track, decoupler and disturbing plate, the influences of the three hydraulic mechanisms, the length of the inertia track or the diameter of the orifice on the dynamic properties were studied experimentally.
Open image in new window Fig. 6 Production performances for different values of hydraulic fracture half-length.
The stilling basin works have been evaluated by the determination of its depth, the hydraulic jump, jet lengths and the combined depths of the hydraulic jump.
