Patent ID: 7231331

Claim:
A method of determining crack locations associated with a tubular member, the method comprising: locating a set of stress corrosion cracking indicators associated with a tubular member; locating a set of low-level corrosion indicators associated with a tubular member; comparing locations of the set of stress corrosion cracking indicators with locations of the set of low-level corrosion indicators; establishing a subset of stress corrosion cracking indicators and a subset of low-level corrosion indicators when the location of any of the set of stress corrosion cracking indicators is located within a first preselected distance from any of the set of low-level corrosion indicators; locating a set of soil characterization indicators associated with the tubular member; comparing locations of the set of soil characterization indicators with locations of the subset of stress corrosion cracking indicators and locations of the subset of low-level corrosion indicators; establishing a plurality of predictor stress corrosion cracking indicators, a plurality of predictor low-level corrosion indicators, and a plurality of predictor soil characterization indicators when the location of any of the set of soil characterization indicators is located both within a second preselected distance from any of the subset of stress corrosion cracking indicators and within a third preselected distance from any of the subset of low-level corrosion indicators; and predicting at least one of a plurality of locations associated with the tubular member susceptible to stress corrosion cracking responsive to at least two of the plurality of predictor indicators.
