||The use of oil and gas as an energy source is and will be a major part of the energy consumed globally in the near future. The increase in the demand for energy is fueling non-conventional oil discoveries. For example, deep sea exploration and drilling present unique service conditions in which materials are exposed to complicated geological formations, complex stress/strain loading cycles and crude oil/gas products at elevated temperatures, high pressures and often with high sulfur and/or chloride contents. Components installed at the ocean floor are difficult to service and are expected to provide satisfactory performance for the life of service. Offshore platforms are expected to withstand all types of weather which can further complicate safe, uninterrupted operations. These demanding service conditions require high performance materials with unique property and performance characteristics. New and improved materials such as high strength structural steels, improved tool steels, duplex and super-duplex stainless steels, precipitation hardened (P-H) stainless steels and nickel-based superalloys are of particular interest along with more traditional materials such as carbon or low alloy steels and non-metallic materials. Surface treatments and coatings are also important in these applications to further improve the bulk material performance. This symposium will provide a forum to present recent developments in new alloys/materials, surface treatments, and characterization of microstructure-property relationships to further improve product performance for these demanding applications with a special emphasis on deep sea exploration and drilling. Degradation modes such as corrosion, environmental cracking, fouling, scaling, etc. are also of interest. Related developments in land based shale operations will also be discussed as the carbon foot print dominates the global energy requirements.
