2021.9.1 Abstract. Proppant transport is a critical physical process in hydraulic fracturing which has been extensively used for reservoir stimulation in petroleum engineering. Proppants injected together with fracturing fluid provide structural support to the stimulated fracture network and prevent them from closing after flowback.

In order to analyse elucidate the factors controlling the phenomenon of proppant transportation, volume percent of sand (proppant), proppant density, fluid viscosity, fluid velocity, and proppant diameter have been examined in this study.
Read More2020.11.17 The experimental results showed that proppant transport occurred under a combination of fluidization and sedimentation in both nonviscous fluids and viscous fluids, primarily dragged by fluidization. The proppant neither penetrates the full length of the fracture nor completely fills it but forms a sand dune in the fracture.

Proppant is small granular material, which is placed into hydraulic fractures during geothermal and hydrocarbon reservoir stimulation.

Proppant flowback and pack rearrangement in the fracture. Downhole proppant scaling. Most proppant choices are currently based on which one has the highest baseline conductivity, cost,
Read More2023.2.8 Conventional proppants have the problem of proppant flowback and the inability to fully distribute along long fractures. To solve these problems, coated proppants have emerged and have been successfully used in many oilfields. Polymers are widely used in the petroleum industry, and one of their functions is for proppant coatings.

Read More2022.2.3 Proppant is often used during the well stimulation operations to keep the fractures open after the fracturing process is complete. If you are not familiar with fracturing, it is a process that involves pumping fluid, chemicals, and proppant at high pressure down the wellbore to create fractures in the formation and allow hydrocarbons to flow more

Read More2023.9.25 Hydraulic fracturing, a highly efficient well-stimulation technique, can be utilised to significantly increase production from unconventional low-permeability rocks like shale. This is achieved through creating fractures in the formation by injecting a solution of water, sand, and chemicals. These fractures may make it easier for the hydrocarbons to
