This paper describes an extended-well-test campaign using intelligent completions in a presalt reservoir. To understand reservoir behavior during production better, several options were analyzed for the first extended well test. Drilling wells provides valuable rock and formation knowledge; however, this information is not sufficient to simulate formation-flow behavior during the field life cycle and reduce production uncertainties. A triple-zone intelligent completion was envisioned as the optimal solution to understand how each interval would behave under production or injection.
Introduction
Presalt represents an important driver of the oil industry in Brazil because it is responsible for a large percentage of the total oil being produced in the country.
