Experimental Study of Sand Distribution among Perforation Clusters in Horizontal Wellbore of Shale Gas Reservoir

Journal of Chemistry, 2020
Multistage horizontal fracturing is the key technique in developing shale gas reservoirs. In each stage, several perforation clusters will be placed to create complex fractures, and the parameters of perforation clusters are almost the same, so the ...

Sand-carrying thresholds of viscous slickwater: Weissenberg number–based prediction and field application

Natural Gas Industry B
The complex viscoelastic and shear-thinning behavior of slickwater fracturing fluids imposes competing effects on proppant transport, complicating the prediction of sand-carrying capacity and increasing the sand plugging risk.

A comprehensive review on proppant technologies

Petroleum, 2016
The main function of traditional proppants is to provide and maintain conductive fractures during well production where proppants should meet closure stress requirement and show resistance to diagenesis under downhole conditions. Many different proppants
