Calibração de modelos para escoamento bifásico aplicado em engenharia de petróleo

Abstract

Computer simulations accelerate the project development cycle and allow to acquire greater knowledge about the simulation model and about the model development process for system improvements. However, making predictions of physical systems is not simple, as there are many uncertainties related to model inputs, parameters and observations. In the oil industry, computer simulations are usually used to predict the performance of oil reservoirs in different extraction scenarios. The computational model parameters are adjusted to the petrophysical properties of the reservoir and the production data to predict the production profiles. However, some key features of these models, such as relative permeabilities, are difficult to measure experimentally. This work proposes a workflow to calibrate the relative permeability parameters from a two-phase flow model.
