Abstract Hydraulic fracturing is regarded as an effective tool to stimulate the reservoir and ensure economic production of gas. The process of exploitation of these resources is largely influenced by small spheres called proppants. The main goal of hydraulic fracturing is to generate a wide fracture network in the medium.

Influences of Proppant Embedment and Deformation on Micro-Sized Graded Proppant Injection Scheme
SPE Asia Pacific Oil & Gas Conference and Exhibition, 2020Abstract The method of micro-sized graded proppant injection has been proposed in the industry to increase the size of the stimulated zone in naturally fractured reservoirs, especially CBM. However, big discrepancies between the modelling results of graded proppant injection and the experimental results have been observed.

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.

New Experimental Methods to Study Proppant Embedment in Shales
Rock Mechanics and Rock Engineering, 2021Productivity in fractured wells typically declines when severe proppant embedment shrinks the fracture aperture and creates conductivity clogging fines. However, the mechanisms linking embedment to decline are poorly characterized. In the absence of this understanding, very few models take proppant embedment into account when predicting production ...

Abstract The method of micro-sized Graded Proppant Placement (GPP) has been proposed in the industry to increase the size of the stimulated zone in naturally fractured reservoirs. The models of determining the Optimal Proppant Packing Ratio (OPPR) and the optimal injection schedule have also been established.

The influence of proppant breakage, embedding, and particle migration on fracture conductivity
Journal of Petroleum Science and Engineering, 2020Abstract Many studies that aim to reduce the damage to fracture conductivity caused by proppant breakage and embedding have been conducted. Few studies, however, have addressed the damage to conductivity caused by proppant particle migration, which is often neglected in practical design.

Experimental Analysis of Proppant Embedment Mechanism
Chemistry and Technology of Fuels and Oils, 2018Proppant embedment in hydraulic fracturing can reduce remarkably the fracture width and thus damage the fracture conductivity. This paper describes a study of the proppant embedment mechanism. Two groups of experiments were carried out. A proppant embedment mechanism was proposed. An analysis showed that proppant embedment is not an elastic process but

Mechanism of Single Proppant Pressure Embedded in Coal Seam Fracture
Energy & Fuels, 2021The strength and rigidity of proppant and coal are quite different. Proppant is easily embedded in coal, resulting in the decrease of fracture aperture and conductivity. The mechanism of proppant embedded in the coal fracture surface needs further study.

New Mathematical Models for Calculating Proppant Embedment and Fracture Conductivity
SPE Journal, 2012SummaryProppant embedment plays a significant role in decreasing fracture aperture and conductivity, especially for weakly consolidated sandstones, shale (oil and gas) rock, and coalbeds. Empirical and semiempirical models were usually used to calculate the embedment of proppants.
