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 >
