A subsea oil production system allows simultaneous production of several wells with different flow rates when the system has a subsea manifold. In order to balance the different flow rates, the higher production wells have their flow rates reduced via a choking system. As a result, the total flow is lower than the summmation of all individual well flow rates. But, this combined and lower production has a very attractive economics, as it requires lower capital expenditures, mainly due to the shorter overall length of flowlines and lower number of risers and, also due to the expected lower operational costs. Nowadays, however, with the availabity of the technology of subsea multiphase pumping system, which enables the transfer of energy to multiphase mixtures (oil, gas and water) under production, becomes possible to achieve an even higher and more attractive plateau in these petroleum production systems. This new equilibrium plateau, made possible by the technology of subsea multiphase pumping, will lead to production levels that will attempt to take benefit of all reservoir allowance and then extending the primary production limit imposed by the production system characteris tics (e.g., flowline length, water depth, produced fluid properties etc.). This novel scheme that allows obtaining a now and higher production level is being called in the literature as Positive Choking. Therefore, based on the resultant aspects of production flow rate increase - production anticipation - and on the potentially higher recovery factors - larger produced volumes - is what drives the belief that such technology can be economically attractive to new production systems being installed or even in those already in operation. The purpose of this work is to contribute in the technical and economical evaluation of Multiphase Pumping System application on a subsea production system equipped with a manifold.
