A Method for Correcting Dimensionless Fracture Conductivity for Non-Darcy Flow Effects (SPE 20710)

It is often assumed that a fracture should be designed to achieve a dimensionless fracture conductivity (CfD) of 10 to optimize economic potential of the fracture treatment. However, unless the fracture conductivity is corrected for non-Darcy effects, this guideline will provide a serious deficiency in fracture conductivity and a well that falls short of the expected productivity.

This paper provides a method for adjusting the fracture conductivity to compensate for non-Darcy flow. The correction requires knowledge of the expected producing rate and calculation of a Reynolds number characterizing flow in the fracture near the wellbore.
