Resumo:
This paper makes the comparison between models of pressure drop during heavy oil
flow. Set up an analytical model from real data operation, where it is compared to
Brauner and Arney models and experimental data found in literature. In spite of current
crisis involving oil industry, it has grown significantly in face of its abundance in the
country. This industry offers various productive processes and elements ranging from
production to refining and distribution for consumer units. One of this is pumps that are
responsible for transporting crude oil to be processed into end products available to
consumers. By the foregoing, it is evident the need for advanced studies on energy
consumption dependence of pumps for heavy oils, physicochemical properties of fluids
involved and the contribution of water used as a vehicle for transport of such oil.
Seeking to meet this demand and from this idea, present work was developed to identify
theoretical models and to search empirical results with ultimate goal of evaluating water
optimal amount in a binary liquid water-heavy oil mixture for potiguar basin fields.
Data were obtained from literature surveys, meetings and technical visits on a Petrobras
SA workstation, located in Rio Grande do Norte state. Pressure reduction factor,
pumping power, energy consumption and water production reuse results are presented
and discussed for comparison between models. It was found that Brauner model was
one most suited to field actual profile, with a small difference for very poor or very rich
mixtures in oil.
