Study of Alternative Technology for Increasing Oil Recovery Factor on Mature Oil Fields

Abstract:

A determining factor in the development of mature oil fields is the natural depletion suffered by the reservoirs as a function of time. The use of technologies that allow the increase or sustainable maintenance of oil production is essential to achieve the development of these mature oil fields. Technologies such as polymer flooding, which allows to increase the energy of the reservoir, and increase the oil sweep. The objective of this work is to determine the best polymer injection scenario, if any, through the application of numerical reservoir simulation, in the mature oil field of the Ecuadorian coast, to increase the oil recovery factor. The scenarios will be simulated with data from level B of the Socorro formation of the mature oil field, partially hydrolyzed polyacrylamide polymers (HPAM) and sulfonated polyacrylamide AN125VHM will be used, at different concentrations and injection rates. Finally, the economic analysis will be carried out with the net present value (NPV) and the internal rate of return (IRR).
