Numerical Modeling of Proppant Embedment in Viscoelastic Formations with the Fractional Maxwell Model [PDF]
ACS Omega, 2021 Hydraulic fracturing is often used to exploit unconventional hydrocarbons, and proppants are usually added during hydraulic fracturing to keep the fractures induced open. Nevertheless, time-dependent proppant embedment has often been neglected in previous studies.

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 ...

Studies of Fracture Damage Caused by the Proppant Embedment Phenomenon in Shale Rock [PDF]
Applied Sciences (Switzerland), 2019 This paper concerns the effect of proppant embedment related to hydraulic fracturing treatment. This phenomenon occurs if the strength of a dry reservoir rock is lower than that of proppant grains.

Influence of Proppant Size on the Proppant Embedment Depth. [PDF]
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-

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.

Preliminary Studies on the Proppant Embedment in Baltic Basin Shale Rock [PDF]
Rock Mechanics and Rock Engineering, 2021 AbstractProppant embedment is a serious issue that reduces fracture width and conductivity. The paper presents the results of experiments on embedment phenomena on a shale rock from the region of the Baltic Basin, which is regarded as an unconventional gas deposit.

Proppant embedding-based optimal design method for fracturing coalbed methane wells in Qingshui basin [PDF]
Scientific ReportsFracturing design needs to consider the effect of proppant embedding as the production decreases rapidly due to proppant embedding after fracturing of coalbed methane wells.

Study on the evaluation method and influencing factors of fracture conductivity of hydraulic fracturing support in shale reservoir [PDF]
E3S Web of Conferences, 2021 The conductivity of supporting fractures is an important parameter to evaluate the hydraulic fracturing effect of shale reservoirs, and its size is affected by many factors. In this paper, the proppant is optimized and evaluated on the basis of real rock

Mechanical behavior of hollow proppants based on finite element model
Energy Science & Engineering, 2021 Proppants are being increasingly used in hydraulic fracturing, which keep the fractures open. Progress has been made in developing hollow proppants that can be transported to the far end of the fractures to improve propped fracture conductivity.
