Proppant embedment in rough fractures considering shale hydration
Energy Reports, 2023 Shale reservoirs are significantly hydrated owing to the presence of large amounts of clay minerals. However, the mechanical properties of the hydration layer on the rock surface decline, resulting in severe proppant embedding.

Calculation method of proppant embedment depth in hydraulic fracturing
Petroleum Exploration and Development, 2018 For the issue of proppant embedment in hydraulic fracturing, a new calculation method of embedment depth considering elastic-plastic deformation was proposed based on the mechanism of proppant embedment into rocks by combining proppant embedment constitutive equations and contact stresses on the rock-proppant system.

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-
