Resumo: | Oil recovery using waterflooding has been until now the worldwide most
applied method, specially for light oil recovery, its success is mainly because
of the low costs involved and the facilities of the injection process. The Toe-
To-Heel Waterflooding TTHWTM method uses a well pattern of vertical injector
wells completed at the bottom of the reservoir and horizontal producer wells
completed at the top of it. The main producing mechanism is gravitational
segregation in short distance. This method has been studied since the early
90´s and it had been applied in Canada with positive results for light heavy
oils, nevertheless it hasn´t been used in Brazil yet. In order to verify the
applicability of the process in Brazil, a simulation study for light oil was
performed using Brazilian northwest reservoirs characteristics. The simulations
were fulfilled using the STARS module of the Computer Modelling Group
Software, used to perform improved oil recovery studies. The results obtained
in this research showed that the TTHWTM well pattern presented a light
improvement in terms of recovery factor when compared to the conventional 5-
Spot pattern, however, it showed lower results in the economic evaluation |
