Catastrophic failures of drillpipes have to be prevented from occurring during drilling operations of oil and natural gas wells. The National Energy Technology U.S. Department of Energy and DNV are investigating mechanisms of crack propagation in ultra-high strength low alloy (UHSLA) martensitic steel drillpipe under cyclic stress as functions of pH H2S concentration and temperature in simulated production fluids. These fluids are deaerated 5%NaCl solution buffered with NaHCO3/Na2CO3 or CO2 in contact with 0.83 kPa H2S. Microscopic investigations of the pre-cracked sample surfaces after corrosion fatigue tests in neutral pH solution at 20 and 200°C respectively revealed that the environment temperature affected not only the crack propagation mode but also a general corrosion behavior. This paper discusses effects of the production fluid temperature on susceptibility of the UHSLA steel to environmentally assisted cracking. Post-corrosion fatigue surface characterization methods such as optical and scanning electron microscopies were used in this study.
