Influence of Proppant Size on the Proppant Embedment Depth
ACS Omega, 2022 Hydraulic fracturing is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid, in which proppants are added to keep the fracture open after the fracturing operation. The scale discrepancy between the rock specimen and the proppant may bring deviations in the analysis of proppant embedment depth if the fluid-

Numerical simulation of multi-cluster proppant distribution in horizontal wells
Shenzhen Daxue xuebao. Ligong ban, 2022 For the staged multi-cluster fracturing of horizontal wells, the distribution of fracturing proppant inside different perforations directly affects the placement of proppant in the fracture, which in turn affects the fracturing performance.
