The use of wirelines in the operation of sour gas and oil wells is a common and needed activity. These wirelines must be high strength, and they must resist corrosion by the environments of such wells, environments that cause stress-corrosion cracking (SCC) of many alloys. Specially prepared samples of 17 alloys, including austenitic stainless steels, a duplex stainless steel, nickel-base alloys, a cobalt-base alloy, a nickel-cobalt and a titanium alloy, were tested in seven environments in the laboratory to measure their resistance to SCC. Simulated sour well environments were included among the tests. Mechanical properties also were measured. A system was devised to rank the alloys based on the corrosion test results. The authors report that, considering also the mechanical properties requirements, the Ni-Cr-Mo-W-Fe alloys rate highest and best for sour well wireline applications.
