... The pseudo-skin function is defined: (3) f=ln ζ ∞ + Δ S f where ΔS f – finite conductivity fracture skin. The parameter ΔS f describes the skin factor of a fracture with finite conductivity, i.e. additional filtration resistance of the fracture due to its final...

... fracture conductivity, and skin factor are sensitive to variations in pumping schedule design and pulsing strategy. We perform fracturing simulations using an advanced high-resolution multiphysics model that includes coupled 2D hydrodynamics with geomechanics (pseudo-3D, or P3D, model), 2D transport...

... Abstract Production history fitting in Weiyuan shale gas shows that the length and height of supporting fractures are short, which limits the long-term conductivity of fractures. Due to the limited volume of reconstruction, the production decreases rapidly, which makes it difficult to achieve...

...-based fracturing fluids to synthetic ones. Highly viscous friction reducers find wider application in the new concept of modern industry development. Unlike traditional guar-borate-based fluids, these fluids have a number of advantages - they provide higher residual fracture conductivity, are less...

... Abstract Fluid flow in fractures is of great interest in the oil and gas industry due to its numerous applications in naturally and hydraulically fracture reservoirs. In order to resolve a fracture's conductivity, its structural and hydraulic properties must be analyzed extensively...

However, even in this case retained fracture conductivities are typically not higher than 60-70%, especially in cases when hybrid fluid systems are used - linear...

... Abstract Predicting naturally fractured carbonate reservoir behavior is associated with fluid flow modeling of two and more mediums. Presence of highly conductive faults and fractures complicates the process. These complications are generally addressed by common approaches using DPDP models...

... Abstract Hard-to-recover reserves, including low and ultra-low-permeability reservoirs, where conventional high-conductivity hydraulic fracturing approaches are not applicable, require revision of standard fracturing design approaches. The Vinogradova field in Beloyarsky district, Russia...
