Resumen:
The use of glass fiber reinforced polymers pipes (FRP) has been explored by petroleum operators as an alternative to stainless steel, duplex/super duplex and chrome alloys mainly due to the resistance of FRP to electrochemical corrosion. Moreover, their relative light weight allows handling and installation that is particularly beneficial for retrofit applications. Mature reservoirs are characterized by increased water cut (i.e. increased produced water) and reservoir depletion which requires water injection to maintain reservoir pressure. The produced and injected water is highly corrosive, resulting in premature failure of traditional materials. As a result, the use of FRP based on epoxy seems to be an alternative for applications in those corrosive environments. Despite the advantages of FRP pipes, their application is still limited mainly due to inadequate knowledge of failure mechanism and unsatisfactory methods of evaluating the deterioration. Long-term durability of glass-epoxy composite pipeline in service is an industrial important issue mainly because the consequences of failure are severe in oil and gas applications; and it is also a scientific challenge because it includes many variables (resins, fibers, design, manufacturing, and environment). It is important to determine how the resin, fiber and interface are affected in terms of long-term property degradation by chemicals and downhole thermal conditions. In addition, the effect of hydrodynamic and complex multiaxial loads on degradation needs to be addressed.
