The rising demand for energy combined with our depleting natural oil and gas reserves has led to oilfield operations being conducted in environments which were formerly considered too harsh. Consequently, there has been a constant demand for improved materials and processes to allow operation in these hostile conditions. Low alloys steels have limited corrosion resistance in CO2 environments and Stainless steels have limited resistance in chlorides, hence nickel based alloys are recommended. Embrittlement, the loss of ductility of a metal due to absorption of H2S or hydrogen, resulting in catastrophic failures, has posed a significant challenge to those designing microstructures capable of surviving such environments. In this presentation, technological advancements in materials from new superalloys, coatings and grain-refined nanocrystalline materials to survive extremes of temperature, pressure and corrosive fluids in the oil and gas industry are highlighted. Surface modifications to refine surface morphology to increase corrosion resistance are also discussed.
