Numerical simulation of proppant transport in hydraulic fractures with length-dependent variable aperture [PDF]
Scientific ReportsHydraulic fracturing is vital for enhancing oil and gas production. Proppant transport governs fracture conductivity and is therefore critical. Most studies simplify fractures as constant-width structures, inconsistent with real variable-width fractures ...
