RESUMO

The oil field industry has been drilling in different scenarios, subjected to high pressures and high temperatures in deep wells located in deep and ultradeep waters. The well control study in these scenarios demands a kick simulator capable to do precise predictions of the pressure behavior inside the wellbore during a kick situation. Regarding this scenario, a kick simulator has been implemented. The simulator is based in a mathematical model that solves a set of three conservation equations using the finite difference approach. The effects of the frictional pressure losses, the gas slip and expansion have been incorporated to the model. The model is capable of simulating a single kick in a vertical or horizontal hole, onshore or offshore, with water-based drilling fluid. The simulator results have been compared with experimental data and the effect of some important parameters in well control has been studied
