Evaluation of numerical schemes for capturing shock waves in modeling proppant transport in fractures
Proppant transport Hyperbolic partial differential equations Frac pack Hydraulic fracturing
2018/4/2
In petroleum engineering, the transport phenomenon of proppants in a fracture caused by hydraulic fracturing is captured by hyperbolic partial differential equations (PDEs). The solution of this kind ...
