Simulação da injeção de bancos de agua com polimeros na recuperação de petroleo

TL;DRAbstract

In this presentation we work on the problem of the injection of water banks with polymers in enhanced oil recove:ry. The mathematical model consists of a system of conservation laws with appropriate initial conditions and of boundaries. We have used the solutions of the Riemann problem ( [ISA] and [JOH] ) associated to this system to propose an algorithm which calculates the profiles of saturation of water s(x,t). The outlining conditions are given through the size of the water banks ( or water whit polymers ) and the polymer concentration used in the injector well. The difficulties found are due to the treatment of the discontinuities that appear due to the interaction among rarefaction and shocks that are formed because of the solution o f the Riemann problem and the discontinuities in the outlining conditions. We have made program computer which calculates the interaction among the shocks, the solution of the Riemann problem and the solution of the banks injection problem. Cases wit
