Numerical Investigation of the Effect of Partially Propped Fracture Closure on Gas Production in Fractured Shale Reservoirs

Energies, 2020
Nonuniform proppant distribution is fairly common in hydraulic fractures, and different closure behaviors of the propped and unpropped fractures have been observed in lots of physical experiments.

Investigating the Impacts of Nonuniform Proppant Distribution and Fracture Closure on Well Performance in Shale Gas Reservoirs

Frontiers in Earth Science, 2022
The nonuniform distribution of proppant in hydraulic fractures is an essential factor determining the accuracy of well performance evaluation in shale gas reservoirs. In particular, unpropped and propped parts hold distinct closure behavior. To study the

An optimization model for conductivity of hydraulic fracture networks in the Longmaxi shale, Sichuan basin, Southwest China

Energy Geoscience, 2020
Shale gas is an important unconventional resource. The economic recovery of shale gas is only possible when a fracture network with sufficient conductivity is created by hydraulic fracturing, that, if effectively propped, connects fracturing fractures ...

The effect of combined proppants upon the fracture conductivity in tight gas reservoirs

Energy Reports, 2020
Sand and ceramic proppant are the most commonly used materials to keep fractures open during hydraulic fracturing. Ceramic proppant has higher hardness and sphericity than sand, but it is much more expensive.
