Fracture Conductivity Prediction Based on Machine Learning. [PDF]

open access: yesACS Omega
Hydraulic fracturing technology is the main method to develop low-permeability reservoirs. Fracture conductivity is not only the basis of fracture optimization design but also one of the key parameters to determine the effect of hydraulic fracturing.

The effect of combined proppants upon the fracture conductivity in tight gas reservoirs

open access: yesEnergy Reports, 2020
Sand and ceramic proppant are the most commonly used materials to keep fractures open during hydraulic fracturing. Ceramic proppant has higher hardness and sphericity than sand, but it is much more expensive.

Hydraulic conductivity of rock fractures [PDF]

open access: yesTransport in Porous Media, 1996
The flow of a single-phase fluid through a rough-walled rock fracture is discussed within the context of fluid mechanics. The derivation of the ‘cubic law’ is given as the solution to the Navier-Stokes equations for flow between smooth, parallel plates - the only fracture geometry that is amenable to exact treatment. The various geometric and kinematic
