A model of hydraulic fracturing with fracture plugging mechanizm
Petr Vladimirovich Karnakov, Vasily Nikolayevich Lapin, Sergei Grigoryevich Cherny

Abstract
One-dimensional model of hydraulic fracturing with proppant transport is proposed. Proppant transport is simulated in one velosity approach. Viscosity of the mixture is written as a function of proppant concentration to take influence of proppant on fluid flow into account. Viscosity supposed to be equal to infinity if proppant concentration reaches the critical value. In order to simulate inequality of fluid and proppant velocity fields the original submodel of fluid filtration is introduced. The developed model allows to simulate the effect of fracture plugging that is observed in fields. Submodel of fluid filtration shows that proppant concentration in the plug at fracture tip decreases because of fluid filtration from the plug vicinity. The influence of pump schedule on fracture length is investigated using developed model.

Key Words
hydraulic fracturing, proppant transport, PKN-model, plug at fracture tip
