Sensitivity analysis of production parameters in multiphase flow simulations

Resumo

With the development of oil fields in ever deeper water depths, the costs involved in exploration and
production have grown drastically. Thus, to make projects more economically attractive, it is necessary to
understand the factors that contribute to maximize production. In hydrocarbon production management, there are
several parameters that involve fluid flow through the production system that can significantly impact field
productivity. The value of these parameters may contain uncertainties that interfere in the platform's short-term
decisions, such as: well opening and closing strategies, choke valve opening, injection parameters, among others.
In this context, the proposed paper aims to evaluate the well test parameters and perform a sensitivity analysis to
verify which parameters have the most impact on the well productivity, through a correlation matrix. The analyzed
parameters are reservoir pressure, productivity index, gas-oil ratio, water cut and gas lift injection rate.
