    Abstract Refracturing has become an important technique for increasing hydrocarbon production due to the low oil prices. During refracturing, the granular diverter materials are injected to temporarily seal old fractures in subsurface. These diverter materials are usually carried by the fracturing fluid, which is a typical solid-fluid flow in the fracture [1-3]. Therefore, we need to thoroughly understand the flow mechanism of diverter materials in hydraulic fractures, which is the key to the success of refracturing treatment.
    Using the Euler-Lagrange method, this paper presents a multiphase model to numerically simulate the flow process of diverter materials in… More >
