The article presents the results of the variable or non-uniform conductivity (width, permeability or both profiles) in the fracture. This allows predict performance of damaged fracture, and so on. Usage the average conductivity of fractures to represent an equivalent constant value has shown that it works well for high conductivity, reduces conduction (i.e ellipsoidal or wedge-shaped fractures) with maximum conductivity in the wellbore. For inverted wedge cracks (conductivity in the well is less than an average) the fracture efficiency will be significantly reduced, and the average conductivity will greatly overestimate the effective value. Moreover, for low-conductivity fractures in the well the equivalent conductivity is weighed more relative to the value of the well than the average. Also the article presents the optimal conductivity of fractures (and fracture sizes) for a given amount of proppant to maximize productivity.
