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.

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.

Theoretical Analysis of Proppant Embedment and Fracture Conductivity in Fractured Reservoir [PDF]
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Proppant embedment mainly accounts for diminishing fracture aperture and conductivity. The conductivity decrease could greatly restrict fluid flow, thereby affecting the well performance. In this paper, new mathematical models are derived to calculate the proppant embedment and fracture conductivity after hydraulic fracturing ...

Influence of proppant embedment on fracture conductivity
IOP Conference Series: Earth and Environmental Science, 2020 Abstract Using the national invention patent equipment, the proppant embedment experiment was carried out on the formation coal seam. The effects of proppant embedment on the conductivity of cracks under different proppant types, different proppant particle sizes, different sanding concentrations and different closing pressures were ...

Comparison of mechanical characteristics of different types of shales in the Ordos Basin
Frontiers in Earth Science, 2023 Shale gas is a very important unconventional energy. The mechanical properties of the three types of shale (laminated shale, sandwich shale and foliated shale) are different, and the difference in fracturing effectiveness is very significant.
